SECTION 1 INTRODUCTION The High Pressure-High Temperature Filter Presses are used for testing the filtration properties of drilling fluids, cement slurries, and fracturing fluids. High-pressure high-temperature filter presses provide an efficient means of evaluating the filtration properties of drilling fluids at high pressures and temperatures. The cells have a filtering area of 3.5 in.2 (22.58cm2). They can be operated at pressures up to 900 psi (6205 kPa) with the compact easily attached CO2 pressuring unit provided. Pressures up to 1200 psi (8274 Kpa) on the cell and 750 psi (5171 kPa) on the back pressure receiver may be obtained using the Nitrogen manifolds, with the nitrogen regulator assemblies. The nitrogen manifolds are provided with safety relief valves set at 1200 psi (8274 kPa) for the cell and 750 psi (5171 kPa) for the back pressure receivers. These filter presses may be operated at temperatures up to 200?F (93?C) using a graduate to collect filtrate. For temperatures above 200?F (93?C), a back pressure receiver must be used to prevent boiling of the filtrate. The standard back pressure receiver has a separate CO2 pressuring source to provide the standard 100 psi (689 kPa) back pressure. Larger volume and/or higher back pressure receivers also may be used. These are connected to the nitrogen manifold allowing for pressurizing up to 750 psi (5171 kPa) backpressure. (If an ion analysis is to be made of the filtrate, nitrogen should be used for the back pressure). The cell of all high-pressure high-temperature filter pressures is encased in a thermostated aluminum well during heating and filtration. The heating chamber completely encloses the filtering area. This assures filtration at the desired temperature. The 175 ml cell units can be operated up to 350?F (177?C), while the 500 ml cell units can be operated up to 500?F (260?C). Either the heating jacket temperature or the cell temperature can be measured using a metal stem thermometer. Insert the thermometer either into the well of the heating jacket or the well of the cell as desired. The temperature is adjusted by means of a knob on the thermostat. The dial has a reference scale of 1 to 10. After the desired temperature is once determined, it may be repeated by setting the thermostat knob to the same reference setting. For operation above 375?F (190?C), the filter paper should be backed with a glass fiber filter. An alternative is a stainless steel filter. Another alternative is the use of a cell adapted to accept a Ceramic filter disc. Power consumption of the 175 ml cell heating jacket is 400 watts, and of the 500 ml cell heating jacket is 800 watts. The standard cells for these filter presses are made of stainless steel. These cells have valves at top and bottom so they can be closed in for heat-up and cool-down. This design also allows the cells to be used for aging and agitation using the Roller Oven before filtration properties of the same sample are determined.

SECTION 2 SAFETY CONSIDERATIONS Safe operation of the High Pressure High Temperature Filter Presses requires the operator understand and practice the correct assembly and operation of the equipment. Improper assembly, operation, or the use of defective parts poses the possibility of cell leakage or failure which could result in serious injury and damage. The sample cell and the heating jacket are hot during operation. The operator should be aware of these hot areas and avoid contact with them. Burns can result from touching hot parts of the equipment during normal operation. These instruments are electrically heated, and as with any electrical device if the wiring is allowed to become faulty electrical shorts can occur causing damage to the instrument and possible injury to the operator. These instruments should always be used on a grounded circuit. Following is a list of suggestions that should be observed to assure safe operation and maintenance of the HPHT Filter Presses. A. Safe Pressurization 1. Always use either Nitrogen or Carbon Dioxide. Never connect the Filter Press to Compressed

Air, Oxygen or other non-recommended gas. If Nitrogen is used it must be supplied in an approved Nitrogen gas cylinder or the nitrogen supply system must be built into the laboratory. Nitrogen Cylinders must be secured to meet safely standards. Carbon Dioxide is normally supplied in small cartridges which contain about 900 psi (6206 kPa) pressure. They are primarily used for field operations. Do not allow these cartridges to be heated or exposed to fire. They can explode if overheated.

2. Maintain pressure regulators in good condition. Never use oil on pressure regulators. Leaking

pressurization systems should be repaired or replaced. Gauges, fittings and hoses should be kept in good condition and leaks should be found and corrected. Periodically test the safety relief valves on the pressurization manifolds to verify they will relieve if excessive pressure should occur. Never plug or bypass these safety valves.

3. When pressurizing the Cell and the Back Pressure Assemblies always open the supply

pressure first, then adjust the regulator. Do not attempt to pressurize higher than the equipment is rated or above the relief valve settings. Follow the procedure as outlined in Section 6-C. When de-pressurizing, shut off the supply pressure, bleed the system of pressure, then back out the regulator Tee screw following the procedures in Section 6E-9.

4

4. Cell assemblies are available which incorporate an indicator on the top of the cell assembly to

show when the cell is pressurized. This is an available and recommended optional safety device in case the normal pressure bleeding procedure does not operate due to plugging or other reasons. If this indicator can be depressed and will stay depressed, there is no pressure in the cell and it is safe to open. If it cannot be depressed or will not stay depressed, the cell has pressure in it and MUST NOT be disassembled. This device is installed in the solid end of single-ended cells, and in the top cap of double ended cells. For part numbers of cells and caps having this safety indicator refer to Section 10.

B. Safe Heating 1. Caution should be exercised by all personnel working with, or working in the area where HPHT

Filter Presses are in operation to avoid accidental injury caused by touching the heating jacket or cell assembly while these are hot. The heating jacket can operate at a temperature where it will cause burns if touched. Safeguard the equipment after the test ends long enough for it to cool. It can still cause burns even after it has been turned off.

2. The practice of removing the cell and cooling it under water is a very dangerous procedure and

is not recommended because of the danger of severe burns if touched or accidently dropped. Also use extreme caution when placing a hot cell in water. Hot steam generated when the water hits the hot cell can cause severe burns. A cell removal tool is available for handling the cell assembly and removing it from the heating jacket. Refer to 10B. Its use will reduce the chances of accidently dropping the cell or being burned by it.

C. Safe Electrical Operation 1. Make sure the electrical source is fused and grounded. Verify the power cord on the Filter

Press is in good condition and has the proper ground connection. 2. Electrical problems in the wiring or heaters may not be obvious by looking at the equipment. If

a malfunction is suspected by the unit blowing fuses or tripping breakers, the heating time seems too long or the thermostat control does not repeat, electrical repair may be indicated. Refer to Section. 9-D or 9-E for repair of the heating jacket. Always disconnect the power cable before attempting any repair.

D. Safe Test Cell Maintenance The filtration Cell Assembly constitutes a PRESSURE VESSEL. The Safety Precautions listed

should be followed to assure safe operation. 1. Cell material should be compatible with the test sample. 2. Cell bodies that show signs of stress cracking, severe pitting, or have damaged set screw

holes must not be used. Refer to Section. 9,A-4. 3. Cell caps showing evidence of the set screw seat being pulled or deformed must not be used.

Refer to Section. 9,A-2. 4. Damaged or "Hardware Store" set screws must not be used. Refer to Sec. 9,A-2.

SECTION 3 DESCRIPTION OF EQUIPMENT High Pressure-High Temperature Filter Presses are available in two sizes, the 175 ml capacity sample cells shown in Fig. 1 and the 500 ml capacity cells shown in Fig. 2. Both series are available with either 115 volt AC or 230 volt AC heating jackets. A back pressure receiver of 15 ml capacity, such as is shown in Fig. 1 and Fig. 4A, is normally used with the 175 ml cells. It is available for use with either Carbon Dioxide or Nitrogen, Fig. 4B, as the pressurizing medium. These 15 ml back pressure receivers also may be connected to the 500 ml cells when a small receiver volume is desired. The 500 ml cells are normally connected to the 100 ml capacity back pressure receiver shown in Figs. 2 and 4C. Whenever test procedures require a larger volume back pressure receiver, either a 150 ml or a 250 ml receiver may be used. Any of these nitrogen pressurized back pressure receivers may be pressurized to a maximum of 750 psi (5171 kPa). All HPHT Filter Presses should be pressurized with either Nitrogen or Carbon Dioxide. Carbon Dioxide capsules, which are self contained and in many applications more convenient to use, normally are used with the 175 ml cells and the 15 cc back pressure receivers as shown in Fig. 1. It should be noted that the carbon dioxide capsules have a maximum pressure of about 900 psi (6205 kPa) and cannot be used if the test requires a higher pressure. In this case, one of the three nitrogen pressurization systems available must be used. Nitrogen pressurization is usually preferred for use with the 500 ml cells because of the greater volume of gas required to conduct the test. The nitrogen manifold commonly furnished has provisions for pressurization of the cell up to 1200 psi (8274 kPa) and to pressure the back pressure receiver to 750 psi (5171 kPa), as shown in Fig. 3A. An alternate available system allows pressurization of the cell to 1200 psi (8274 kPa), but supplies a lower pressure, 170 psi (1172 kPa) maximum, for the back pressure receiver shown in Fig. 3B. The third nitrogen manifold, shown in Fig. 3C, has provision for pressurizing the cell only. In this case the back pressure receiver would be pressurized with carbon dioxide or no back pressure would be used. The desired temperature is adjusted by means of a knob attached to the thermostat. Refer to Figs. 1 and 2. The heating jacket temperature or the cell temperature is measured by inserting a stem thermometer into the thermometer well in the heating jacket or the cell. The thermostat knob has a scale of from 1 to 10 so that after the thermostat has been adjusted using the stem thermometer, the desired temperature may be repeated by setting the knob to the same number. An optional electronic Temperature Controller is available for use with any High Pressure High Temperature Filter Press. Refer to Section 10B. It is used where the tests require precise control of the heat up and test temperatures. This controller controls from its Thermocouple placed in the Thermometer hole in the cell or heating jacket as desired. It controls by rapidly turning on and off the power to the filter press heaters. The relationship between to "ON" time and the "OFF" time per cycle determines the temperature. The option is used by connecting the controller into the power source, then connecting the HPHT Filter Press into the controller. The thermostat on the HPHT Filter Press is turned to maximum temperature (10 on the dial) and becomes a safety over-temperature monitor.

All high pressure-high temperature filter presses use one of two basic cells, one having a nominal 175 ml capacity (Exact capacity is 173.3 ml), and the other having a nominal capacity of 500 ml (Exact capacity of 493.0 ml). Note that if the cell has been modified for a ceramic filter, the volume will be reduced by 11.6 ml. Refer to Section 5-11. These cells are normally made of Type 303 stainless steel. Optional materials such as Type 316 stainless steel or Inconel 600 are also available. They are available in a single end opening style, and in both ends removable or double ended (DBL END) style. End caps with a permanently mounted 60 mesh screen or end caps with a separate removable screen assembly are both available for use with either capacity cell, and with either the single ended or double ended styles. Several screen mesh selections are available for use with the end cap for the removable screen assembly. These are tabulated in Section 5-7 and identified in the Parts Identification for Figs. 5 and 6. Two basic cell bodies are available for use with ceramic disc filters. These cells are available in both the single ended and double ended styles. Note that in the double ended style, only one end is used for the ceramic filter disc. The opposite end is standard and can accept any of the above described end caps. The ceramic filter disc end requires a ceramic filter disc cap. To use these single ended cells and caps for ceramic filter discs with any of the standard filter paper and support screen assemblies, an adapter ring and "O" ring must be assembled into the cell. An addition, any of the above described cell assemblies is available with similar cells which incorporate an indicator on the top of the cell assembly to show that the cell is pressurized. These cell assemblies are illustrated in 6. This is an optional safety device in case the normal pressure bleeding procedure does not operate due to plugging or other reasons. If this indicator can be depressed and will stay depressed, there is no pressure in the cell. If it cannot be depressed or will not stay depressed, the cell has pressure in it and MUST NOT be disassembled. This device is installed in the top end of single-ended cells. (Refer to 6A and 6C) and in the top cap of double ended cells. (Refer to 6B and 6D). Note no screen is used with this safety top cap. Core sleeve adapters are available for mounting cores into any of the standard cells or those adapted for the ceramic filter. Two types of core holders are available. One is a compression type and is designed for use with a 1 inch diameter core. The second type requires mounting the core into the core holder sleeve then assembling the core and sleeve into the cell. Core sleeves are available for 1" or 1 3/4" cores. Both of these core holders are usually used with one of the 175 ml cell, however with the addition of an adapter spacer either one can be used in the 500 ml cells. It is recommended the core holders be used with one of the double ended cells which allows for more convenient assembly. Refer to Section 10B. Certain tests may require the test sample not come in contact with the pressurization medium. This requirement can be met by the use of a free floating piston. The available free floating piston can be used with most cell combinations both the 175 ml and the 500 ml sizes. These pistons are furnished with a suitable installation and removal tool. Refer to Section 10B.

SECTION 6 TEST PROCEDURE The High Pressure-High Temperature Filter Press, if completely assembled, must have the pressuring assembly, the back pressure assembly, and the filtration cell assembly removed from the heating jacket before starting the test procedure as is described below. For easy identification of the several assemblies, reference is made to Figs. 1 and 8 for the 175 ml cell filter presses or Figs. 2 and 9 for the 500 ml cell filter presses. A. Preheating the Heating Jacket 1. Connect the power cord to the proper line voltage as indicated on the nameplate. 2. Turn the thermostat to near mid-scale. 3. Place a metal stem dial thermometer in the thermometer well of the heating jacket. 4. The pilot light will turn on when the heating jacket temperature has reached the thermostat setting. 5. Readjust the thermostat setting as necessary to obtain the desired test temperature. B. Loading the Filtration Cell SAFETY NOTE The filtration Cell Assembly constitutes a PRESSURE VESSEL. The SAFETY

PRECAUTIONS listed in Section 2 should be followed to assure safe operation. Cell material should be compatible with the test sample. Cell bodies that show signs of stress cracking, severe pitting, or have

damaged set screw holes must not be used. Refer to Section 9A-4. Cell caps showing evidence of the set screw seat being pulled or deformed

must not be used. Refer to Section 9A-2. Damaged or "Hardware Store" set screws must not be used. Refer to

Section 9A-2. 1. Loosen the six socket head set screws and remove the cell end cap by pulling it straight out of the

cell, using the valve stem as a handle. If the "O" rings are stuck, screw the cell cap removal tool into the cap valve stem hole then press downward on the handle to pull the cap out. Refer to 10. If the removal tool is not available, it usually can be freed by a rocking motion of the end cap and valve stem. Unscrew the valve stem out of the cap.

2. Check "O" rings on the valve stems, cell body and cap. Replace any damaged or brittle "O" rings.

Replacement of "O" rings is normally required after each test run above a temperature of 350?F (177?C).

28

3. If a double ended cell is being used, repeat 1 and 2 above for the other end cap. 4. If a double ended cell is being used, reassemble the end cap and valve stem which is going to be

the non filter end. Make sure the six socket set screws are securely tightened and the valve stem is tight.

5. For a single ended cell, assemble and tighten the valve stem into the cell body. 6. With the filter end of the cell up, carefully fill the cell with the sample to be tested. Allow 1/2" (12.7

mm) to 3/4" (19 mm) from the top for the 175 cc cells, or the 500 cc cells if the test temperature will be 300?F (149?C) or less. Leave 1-1/2" (38 mm) to 1-3/4" (44.5 mm) from the top for the 500 cc cells for expansion when the sample is to be heated to temperatures between 300?F (149?C) and 500?F (260?C). The 175 cc cells are not recommended for these high temperatures.

7. Position the filter on the "O" ring in the cell body. a. If a permanently attached screen cap and standard filter paper are to be used, place a filter

paper disc on the "O" ring in the cell body. b. If the test is to be run at 400?F (205?C) or above, a backing disc of fiberglass should be placed

on top of the filter paper. c. If one of the removable screens is to be used, install it on the filter paper course side up. d. If a ceramic filter is being used install it directly into the cell omitting the filter paper and

screens. 8. Install the end cap making sure the set screw seats in the cap are aligned with the set screws in

the body. Tighten set screws firmly, then install and tighten the valve stem. (Refer to Section 5-6 "CELL CAPS" for compatibility of end caps).

9. Invert (turn 1800 or end for end) and lower the filtration cell assembly into the heating jacket (filter

end down) and rotate so that the pin in the bottom of the heating jacket will seat into the hole in the bottom of the cell. This prevents the cell rotating when the valve stems are opened or closed.

C. Pressurizing the Filtration Cell 1. For pressurization using CO2, install the pressure unit on the inlet valve stem and insert the locking

pin. a. Check to make sure the regulator "T" screw is backed out (counterclockwise) to release

diaphragm pressure. After the pressure has been released the "T" screw will turn more freely. b. Remove the barrel from the pressure unit and insert one CO2 cartridge into the barrel, blunt end

first. Screw the barrel onto the pressure unit, and tighten the barrel enough to puncture the CO2 cartridge. Do not adjust regulator at this time.

29

2. If a CO2 type back pressure receiver is being used, load a CO2 cartridge in it as described in Section

C1-a and 1-b above. Do not adjust regulator at this time. Refer to Fig. 4A. 3. For pressurizing with Nitrogen, one of the three optional manifolds is assembled onto a nitrogen

cylinder. The 38765 dual manifold is normally provided. Refer to Fig. 3A. The 38766 can be used if the tests will be conducted with 150 psi (1034 kPa) or less back pressure. Refer to Fig. 4B. If the 38767 manifold is used, either no back pressure receiver will be used or the CO2 receiver must be used. Refer to Fig. 3C for the manifold and Fig. 4A for the back pressure receiver.

a. Screw the gland nut into the cylinder valve and position the manifold with the gauges right side

up, then tighten the nut securely. CAUTION

HIGH PRESSURE CONNECTIONS ARE CAPABLE OF CAUSING INJURY IF NOT PROPERLY ASSEMBLED

b. Attach the opposite end of the high pressure hose connected to the 1500 psi (10342 kPa)

gauge side or (left side) of the manifold to the top cell valve stem. Slip the stem adapter manifold on the end of the hose over the valve stem. Secure by inserting the locking pin.

c. Close the bleeder valve on the valve stem adapter manifold. d. Check the "T" screws on the pressure regulators to be sure that they are unscrewed

(counterclockwise) and no pressure will be applied. e. Open the valve on the Nitrogen bottle slowly and carefully. The bottle pressure will be registered

on the middle manifold gauge. 4. Install the back pressure receiver, if used. One of four available Back Pressure Receivers can be

used. Normally the 100 ml receiver, Fig. 4C, is used with Nitrogen Pressurization, however, the 15 ml, the 150 ml or the 250 ml can be used. This depends on the amount of filtrate expected.

a. Install the selected Back Pressure Receiver onto the filter cell lower valve stem and insert the

locking pin. Make sure the drain valve on the back pressure receiver is closed. b. Attach the high pressure hose connected to the 1000 psi (6895 kPa) gauge side (right side) of

the manifold to the inlet of the back pressure receiver and tighten securely. c. If 150 psi (1034 kPa) maximum back pressure is to be used, this would indicate a 38766

manifold is being used. Refer to Fig. 3B which has a 200 psi (1379 kPa) gauge on the right side. NOTE: The 38765 Manifold, Fig. 3A can be used but it is difficult to accurately read the back pressure.

d. Turn the "T" screw on the left hand regulator clockwise until the desired cell pressure is

registered on the gauge.

30

e. Turn the "T" screw on the right hand regulator clockwise until the desired back pressure is

registered on the gauge. Refer to Table 1 below. f. If a CO2 type back pressure receiver is being used, adjust the regulator on it to the desired

back pressure. Refer to Table 1. TABLE 1 RECOMMENDED MINIMUM BACK PRESSURES

D. Conducting the Filtration Test 1. Filtration tests at temperatures below 200?F (93?C) may be performed without the use of a back

pressure receiver. a. Place a graduated cylinder under the cell lower valve stem. b. The time required to heat the sample to the test temperature will be between one half and one

hour, depending on the desired test temperature. The temperature of the cell should be checked by placing a metal stem dial thermometer in the thermometer well of the cell. As soon as the desired temperature is reached, the test may be started.

c. With an adjustable wrench, open the inlet valve stem 1/2 turn. If the pressure on the cell

pressure gauge (left gauge) of nitrogen manifold or gauge on CO2 pressuring assembly has changed from the desired setting, readjust the regulator. If the adjustment is to lower the pressure, momentarily open the bleed valve to reduce the pressure.

31

2. Filtration at temperatures above 200?F (93?C) requires the use of a back pressure receiver. The cell

and the back pressure receiver should both be pressurized to the back pressure value before the cell is heated.

a. With an adjustable wrench, open the inlet valve stem on the filtration cell 1/2 a turn to pressurize

the cell. Readjust the regulators if required. b. If a CO2 type back pressure regulator is being used, load a CO2 cartridge as described in

section C above and adjust the regulator to the desired back pressure. This will pressurize the back pressure receiver. If a dual Nitrogen manifold is being used, adjust the right hand regulator.

c. Allow the cell to heat until the cell is at the test temperature. d. Readjust the cell pressure regulator to the pressure to be used for the test. Note the differential

filtration pressure is the cell pressure less the back pressure. The test is now ready to be started.

3. Set a timer for 30 minutes or other desired filtration test time. Accurate test time is especially

important when the test temperature is above 300?F (149?C). 4. With an adjustable wrench, open the lower valve stem on the bottom of the filtration cell 1/2 turn.

This is the start of the test. 5. Periodically during the test, bleed filtrate from the drain valve on the back pressure receiver into a

graduated cylinder. Use care in collecting the filtrate not to collect all of it while pressure is still applied. This prevents the gas pressure from blowing the filtrate out of the graduated cylinder.

E. Test Conclusion and Disassembly 1. Disconnect the filter press heating jacket from the power source. 2. Close the filtration cell (upper) valve stem and back pressure (lower) valve stem. 3. Release the "T" screws (turn counterclockwise) of both the test filtration and the back pressure

regulators. This applies to either the Nitrogen or CO2 regulators. 4. Open the bleed valve on the test cell manifold and on the back pressure receiver to de-pressurize

the system. 5. The drain valve on the back pressure receiver now may be opened and the filtrate collected. 6. Remove the upper valve stem locking pin and remove the adapter manifold or the CO2 pressuring

assembly from the top valve stem. 7. Remove the lower valve stem locking pin and remove the back pressure receiver.

32

CAUTION

THE TEMPERATURE OF THE SAMPLE IN THE CELL MUST BE REDUCED TO LESS THAN 200?F (93?C) BEFORE THE CELL CAN SAFELY BE OPENED.

BE EXTREMELY CAREFUL IN REMOVING A HOT CELL FROM THE HEATING JACKET. IT CAN CAUSE SEVERE BURNS IF ACCIDENTLY TOUCHED. PLACING THE CELL IN A SINK AND LETTING WATER COOL IT CAN RESULT IN BURNS FROM THE STEAM CREATED WHEN THE WATER FIRST HITS THE HOT CELL 8. The pressurized cell assembly may be left in the heating jacket or it may be removed to another

location for air cooling, or it can be removed from the heating jacket and rapidly cooled with running water. A cell handling tool is available for removing a hot cell from the heating jacket. Refer to Fig. 10B. Attach this tool to the top valve stem using the valve stem locking pin.

9. After the cell and the sample in the cell are cool, the cell may be opened. a. Make sure the open end of the valve stem is pointed away. Then, using the adjustable wrench,

open the top valve stem (the one on the opposite end of the cell from the filter) about 1/2 turn and allow the pressure to bleed off. Make sure all pressure has bled off. If the optional pressure safety indication is on the cell, press the button toward the cell. It should depress to be flush with the cell or cap surface if no pressure exists. DO NOT ATTEMPT TO OPEN the cell if this button will not depress and stay depressed.

WARNING

DO NOT ATTEMPT TO REMOVE THE CELL CAP IF ANY PRESSURE REMAINS IN THE CELL. REMOVING THE CELL CAP WHILE THE CELL IS PRESSURIZED COULD RESULT IN SERIOUS INJURY

If it is suspected the cell may still be pressurized, completely remove the valve stem and

insert a small drill bit or wire into the cell or cell cap to remove the obstruction. Make sure the opening is pointed away from any body parts.

33

b. Once sure that all the pressure has been released, loosen the six socket set screws in the end

cap and using the valve stem as a handle, pull the end cap out of the cell. If the cell cap "O" rings are stuck, screw the end cap removal tool into the valve stem hole in the end cap and press down on the handle to pull the cap out. Refer to Fig. 10A. If the removal tool is not available, a rocking motion of the valve stem will help break them loose.

c. The sample may now be emptied and examined as desired. d. If a double ended cell is being used, remove the second cap as described above. e. The filter cake may now be removed and examined as desired.

SECTION 9 CLEANING, MAINTENANCE AND REPAIR Standard laboratory procedures apply to the cleaning of all models of High Pressure-High Temperature Filter Presses and Back Pressure Receivers. After each test, the cell and the back pressure receiver should be thoroughly cleaned and dried of all sample and other contaminants, with particular attention to "O" rings and "O" ring grooves. Wash and dry screens, or end caps with attached screens. Wipe spilled sample or other debris from the heating jacket and stand. Some sample materials may damage the finish of these parts if allowed to remain on them for a long period of time. A. CELL MAINTENANCE 1. "O" Rings Inspect all "O" rings as they are being cleaned for cuts or nicks and if the "O" rings have been

subjected to over 300?F (149?C). Check for hardening or brittleness. Replace any damaged "O" rings. Lubricate "O" rings before they are installed. For most applications, laboratory stop cock grease is satisfactory; however, since some "O" rings come into contact with the sample, care should be taken that the lubricant is compatible with the sample. "O" rings furnished with the instrument are suitable for testing up to 300?F (149?C). They may be used for one test up to 400?F (205?C). Special Viton "O" rings can be used for repeated testing up to 400?F (205?C), and one test up to 500?F (260?C).

2. Cell Set Screws CAUTION

USE ONLY P/N 38718 SET SCREWS. THESE ARE SPECIAL SET SCREWS FOR THE HTHP CELL.

DO NOT ATTEMPT TO SUBSTITUTE "HARDWARE STORE" SET SCREWS. Cells are assembled using six set screws to retain the cell cap (12 screws for double ended cells).

Safe operation requires the threads of these set screws be kept operating freely. Lubricate the threads with a high temperature lubricant such as Never-Seize®. Inspect the threads and taper points of these screws for damage. Refer to Figs. 5, 6, AND 7, item 2. Replace any screws that have damaged threads or flattened cone points. Inspect the set screw seats in the end cap to make sure the metal is not deformed. Deformed screw seats require replacement of the cap.

40

3. Valve Stems A metal to metal pressure tight seal is made between the valve stem and its seat. Leaks can occur

if either the valve stem or seat is damaged. The cone point of the valve stem may be inspected for damage by removing the valve stem from the cap or body. If the point is damaged, replace the valve stem. Refer to Fig. 11B. If the point appears to be in good condition, the seat in the cell or cap may be rough. A 5/16 inch drill bit can be used to resurface the seat. A tool composed of a 5/16 drill and handle, (Part No. 38717) may be used. Refer to Fig. 11A. Valve stems should be inspected for possible plugging of the passages by dried sample. A small drill or wire can be used to insure that both the cross bore and the main passage openings are clear.

4. Cell Corrosion CAUTION CORROSION PITTING AND CRACKING CAN CAUSE RUPTURE OF CELLS Sample fluids under the temperature and pressure conditions used in this type testing can, at

times, cause corrosion of the test cells and caps. Standard cells are made of Type 303 or Type 316 Stainless Steel. Cells are available in other materials for use where the stainless steels are not suitable because of corrosion problems. An inspection of the inside of the cell for evidence of corrosion should be made periodically. Light corrosion may be removed using 320 or finer wet or dry sand paper. Deeper corrosion pitting may be removed by sand blasting the area of the corrosion. More severe corrosion will require re-machining or re-surfacing the inside of the cell. If machining to 0.020" (0.5 mm) oversize does not remove all corrosion, it is recommended the cell be replaced. If corrosion cracks are evident, the cell should be replaced.

B. PRESSURIZATION SYSTEMS 1. Safety Considerations of Pressure Systems Safe operation of pressurized equipment requires the pressurizing system be properly maintained.

Specific procedures for the safe use of pressure regulators are listed below: a. Never subject a regulator to inlet pressure greater than its rated inlet pressure, as shown on the

regulator body. b. Never use the regulator for gases other than those for which it is intended. c. All connections to the regulator must be clean. Remove oil, grease, or other contaminants from

external surfaces of the regulator and metal connecting parts. d. Before attaching regulator to the cylinder, remove any dirt or foreign matter that may be in the

cylinder valve outlet by wiping with a clean, lint free cloth. CAUTION

THE VALVE ON THE CYLINDER MAY BE OPENED MOMENTARILY TO BLOW THE OUTLET CLEAN. MAKE SURE THE CYLINDER OPENING IS POINTED AWAY FROM PERSONNEL.

e. Never pressurize a regulator that has loose or damaged parts or is in questionable condition.

Never loosen or attempt to tighten a connection or a part until the gas pressure has been relieved. Under pressure, gas can dangerously propel a loose part.

f. Before transporting gas cylinders, remove regulator and recap cylinder. g. Keep cylinder hand wheel or wrench on open cylinder valve at all times, for prompt emergency

cutoff.

45

h. Check regulator and all connections for leaks after installation, periodically thereafter,

and after any service in which parts or connections were disconnected and reconnected, using a soap solution around fittings to find small leaks. Bubbles will indicate a leak.

Pressurization system Troubleshooting Two types of pressure systems are used on the High Pressure-High Temperature Filter Presses.

One is the CO2 system and the second is the Nitrogen system. The primary causes of pressurization system problems with either of these systems are caused by leaking fittings, dirt in the regulators, or faulty pins and seats in the regulator. . Rarely does a diaphragm rupture. If a regulator will not hold pressure:

a. Check for leakage around fittings. Pressure the system and look for escaping gas in the form of bubbles. This can be done by

applying soap suds to the possible leak areas. The regulator assembly, except for the gauge, may be submerged in water. Repair fitting leaks by disassembling, cleaning the threads, then applying a good thread sealant or teflon tape thread sealant before re-installing fitting.

b. Check for a faulty regulator. Check for a faulty pin and seat as evidenced by leakage through the regulator to the down

stream side as opposed to external leakage. Check for bubbles coming out of the regulator when the tee screw is backed out, screwed counterclockwise until the spring pressure is completely released.

c. Check for dirt or sample contamination in regulator. 3. Faulty Regulator Systems One or more of the following conditions will be evidenced when a Regulator is faulty a. Gas leaking at the regulator outlet when the adjusting screw is completely released. b. With no flow through the system (downstream valves closed and adjusting screw in), working

pressure increasing steadily above set pressure. c. Gas leakage from spring case (adjusting screw end of regulator). d. Gas leakage from any point. e. Excessive drop in working pressure with regulator flow open. f. Gas leakage from relief valve. 4. Regulator Repair If it is determined a regulator is faulty, it must be dissembled, cleaned, and repaired as determined

from the above symptom. For disassembly and reassembly Refer to Fig. 12 for the 33700 regulator and Fig. 13 for the 38411 regulator. These procedures are similar.

a. Using a wrench on the hex of the spring cap, unscrew the spring case. All parts down to and

including the diaphragm will remain in the spring case. b. Remove the thrust plate, then unscrew the retainer and remove the seat with the pin. c. Thoroughly clean all parts. Make sure that small orifices are open.

49

d. Inspect the regulator parts. Make sure diaphragm, gaskets, "O" rings and other non-metal

parts are not brittle, cracked or misshaped. Replace these parts as necessary. e. Do not use any oil on the internal parts of the regulator. f. Replace the seat and pin by installing the retrofit kit. g. Reassemble the regulator. Refer to Figs. 12 or 13. h. Pressure test the regulator. Use the list of symptoms above as a check list. i. Assemble required fittings, relief valve and gauges onto regulator. Use a good thread sealant on

all pipe threaded fittings as they are assembled.

14 - HEATING JACKET FOR 175 ML CELLS, EXPLODED VIEW

51

D. HEATING JACKET ASSEMBLY FOR 175 ML CELLS The stand and heating jacket contain the thermostat, cartridge heaters, and power cord used to heat the

cell. Most problems are caused by burned or broken wiring, mis-adjusted or defective thermostat, or burned out heaters.

1. Disassembly of the 175 ml cell heating jacket Refer to Fig. 14. a. Loosen set screw and remove thermostat knob (L7205). b. Remove the two 8-32 x 7/8 long screws holding the thermostat cover (38703) and remove the

cover. c. Remove one 6-32 x 1/4 long screw from the thermostat terminal connection board (38707) then

remove one wire from each heater and the white power wire. d. Remove the two terminal nuts and washers from the thermostat (L8260), then remove the pilot

light assembly (38704), the black power wire, the second heater wire from each heater, and the terminal board.

e. Remove two 6-32 x 1/4 screws holding the thermostat and the green ground wire then remove

the thermostat. f. If the heaters are to be replaced, refer to Section 2-c below. 2. Repair of the 175 ml Cell heating jacket. Refer to Section 11 Wiring diagrams 38700-WI for 115

volt or 38740-W1 for 230 volt. a. After disassembly, inspect all components and replace any burned or broken wires. b. Determine if the thermostat is faulty by connecting an ohmmeter, or continuity tester across the

two screw terminals and noting whether connection is made, then broken by the rotation of the stem. If rotation of the stem does not result in a change on the meter or tester, replace the thermostat.

c. Using an ohmmeter, test the heaters one at a time. An open circuit between the leads

indicates a faulty heater. A shorted heater will show continuity (no resistance) between the leads. Also, test from each lead to the heater sheath or the heating jacket for ground. If the meter shows other than open on this test, the heater is defective. Good heaters will show about 60-70 ohms resistance. Remove and replace any defective heater. If the heaters test good, do not attempt to remove them. If the heater tests defective, remove it by pulling it out of the heating jacket by its leads. It may be necessary to soak the surface between the heater and the heating jacket with penetrating oil or similar product.

3. Reassemble the heating jacket essentially in the reverse order of disassembly, taking note of the

following items. a. If new heaters were installed, the leads should be cut to the proper length to fit neatly onto the

thermostat. New high temperature wire lugs must be crimped onto the heater lead wires after fitting the length. Refer to Section 11, Wiring Diagram 38708-W3 for 115 volt or 38723-W3 for 230 volt for positioning of the wire terminals on the thermostat and terminal connection board.

52

b. When reinstalling the pilot light assembly, make sure the bulb is directly inside the hole in the

thermostat cover. c. Make sure all screws and nuts around the thermostat are tight and all wires properly routed

before replacing the thermostat cover. d. Make sure the insulating paper lining inside the thermostat cover is in good condition and

covers the entire inside front surface of the thermostat cover. If it is torn or missing, replace it using an adhesive to attach it or a new piece to the metal cover.

e. If the thermostat was replaced, it should be checked to see that the stop is properly set. The

stop is the washer shaped part with a tang on it that fits over the grooved stem of the thermostat. At room temperature, and the stem completely counterclockwise, the thermostat should show the heaters on when the heating jacket is plugged into power. As the heating jacket heats, the thermostat should stop the heating. The further clockwise the stem is set, the hotter the jacket be allowed to get. All the way clockwise, (the tang as far as possible clockwise), should be about 350?F (177?C). Should the thermostat stop require resetting, it may be removed from the stem and rotated one or two groves then reinstalled and re-tested.

f. Install the thermostat cover and knob. E. HEATING JACKET ASSEMBLY FOR 500 ML CELLS The stand and heating jacket assembly contains the thermostat, cartridge heaters, power cord, and

insulated cover used to heat the cell. Problems are usually caused by burned or broken wiring, mis-adjusted or defective thermostat or burned out heater or heaters.

1. Disassembly of the 500 ml cell heating jacket. Refer to Fig. 15. a. Loosen set screw and remove the thermostat knob (L7205). b. Turn heating jacket and stand on its side and remove the two 1/2 inch thin nuts (10678) from

the bottom of the base and remove the base (38775). c. Unscrew the two legs (38776) from the heating jacket. d. Remove six screws on front and five screws on top holding front and top sheet metal to the rest

of the case (38778) and remove the front /top sheet metal. e. Remove insulation from between case and heating jacket, then slide heating jacket (38777) out

through front of case. f. Remove one 6-32 x 1/4 long screw from the thermostat terminal connection board (38707), then

remove one wire from each heater and the power wire. g. Remove the two terminal nuts and washers from the thermostat (L8260), then remove the pilot

light assembly (38704), the power wire, the second heater wire from each heater, and the terminal board.

h. Remove two 6-32 x 1/4 screws holding the thermostat and the green ground wire then remove

the thermostat.

53

i. Determine the condition of the heaters. (Refer to Section 9D-2c). If they are to be replaced, remove them by pushing the two bottom heaters out through the bottom of the heating jacket then pulling the two top heaters down past the wiring groove and out the bottom of the heating jacket by their leads. It may be necessary to soak them with penetrating oil or similar product to aid in loosening the cartridge heater housings from aluminum heating jacket.

55

2. Repair of the 500 ml heating jackets is similar to that as outlined above for the 175 ml cell heating jackets. Refer to Section 9D-2 above and to wiring schematics 38770-W1 for 115 volt and 38771-W1 for 230 volt for troubleshooting and wiring layout 38770-W3 for 115 volt and 38771-W3 for 230 volt for positioning of the wire terminals on the thermostat and the terminal connection board.

3. Reassemble the heating jacket essentially in the reverse order of disassembly, taking note of the

following items. a. If new heaters are to be installed, first install the top two heaters. Assembled from the bottom leads

down. After the heaters are in place above the wiring grove, pull the leads into the wiring groove. Next, assemble the two bottom heaters with the leads in first. Pull the leads into the wiring groove as the heater is inserted into the jacket.

b. The leads should be cut to the proper length to fit neatly into the wiring groove and around to the

thermostat. New high temperature wire lugs must be crimped onto the heater lead wires after fitting them to the proper length.

c. When reinstalling the pilot light assembly, make sure the bulb is directly inside the hole in the

thermostat cover. This may require temporarily placing the heating jacket in its cover and positioning the front/top sheet metal in place to determine the position of the pilot light hole.

d. Make sure all screws and nuts around the thermostat are tight and all wires properly routed before

installing the heating jacket in its case. Refer to wiring layout No. 38770-W3 for 115 volt or 38771-W3 for 230 volt units.

e. Reinstall the insulation between the heating jacket and the case. New insulation is suggested if the

old has deteriorated or appears to be burned. f. Make sure the electrical insulating paper inside the front sheet metal cover is in good condition. If

it is torn, loose, or missing, repair or replace it. Use a suitable adhesive to re-attach this paper or to attach a new piece of paper to the inside of the front cover.

g. If the thermostat was replaced, it should be checked to see that the stop is properly set. The stop

is the washer shaped part with a tang on it that fits over the grooved stem of the thermostat. At room temperature, and the stem completely counterclockwise, the thermostat should show the heaters on when the heating jacket is plugged into power. As the heating jacket heats, the thermostat should stop the heating. The further clockwise the stem is set, the hotter the jacket be allowed to get. All the way clockwise, (the tang as far as possible clockwise), should be about 350?F (177?C). Should the thermostat stop require resetting, it may be removed from the stem and rotated one or two groves then reinstalled and re-tested.

h. Install the legs and base and tighten securely. i. Install the thermostat knob.
