Introduction:

Qatar: Qatar, also known as the country or State of Qatar or locally Dawlat Qaṭar, is a sovereign Arab

state, located in Western Asia, occupying the Qatar Peninsula on the northeasterly coast of the

much Arabian Peninsula. Its sole land border is with Saudi Arabia to the south, with the rest of its

territory surrounded by the Persian Gulf. A strait of the Persian Gulf separates Qatar from the

nearby island state of Bahrain.

Qatar has the world's highest per capita GDP and proven reserves of oil and natural gas. Qatar tops

the list of the World's richest countries by Forbes. In 2010, Qatar had the world's highest GDP per

capita, while the economy grew by 19.40%, the fastest in the world. The main drivers for this rapid

growth are attributed to ongoing increases in production and exports of liquefied natural gas, oil,

petrochemicals and related industries.

The Qatari government considers industry to be an integral part of its plan to diversify the economy

and maximise its huge natural gas reserves, which serve as the primary feedstock for the sector.

Accordingly, careful planning has gone into industrial development. With an eye towards exports,

development has been clustered around the ports of Ras Laffan and Mesaieed, which are also key

centres of energy. The result has seen considerable growth over the years. Industries Qatar (IQ), a

producer of petrochemicals, fertilizers and steel, is a regional powerhouse, surpassed only in size by

Saudi Basic Industries Corporation (SABIC), the Middle East’s largest chemical producer.

Page 2

Qatar Petrochemical Company (QAPCO): Qatar was the first Persian Gulf state to build its own petrochemical industry. Established in 1974,

Qatar Petrochemical Co. (QAPCO) is one of the leading petrochemical producers and suppliers in

the world, and began full commercial production in 1981.

As a global company with networks all around the world, QAPCO serves over 4000 customers

through its liaison offices which are strategically positioned in key countries across the globe.

The main products of QAPCO are Ethylene, Low Density Poly Ethylene, and Sulphur, which is an

additional sellable commodity generated as a byproduct in the production process.

TRAINING ACTIVITY

QAPCO Maintenance Department: Maintenance department of the QAPCO is responsible for the maintaining plants at the QAPCO

complex. Moreover maintenance department also implement and supervise the up gradation of the

plants at QAPCO, provided by the engineering services department, which under take study for up

gradation and provide maintenance department with the paperwork and plans required for the up

gradation at QAPCO. Maintenance department is broadly divided into following sections depending

upon the job they undertake:

Auto control and Electrical

Mechanical

Planning

Quality and Services

GSD

Maintenance department also have two workshops, one for mechanical works and other for the automation and electrical related tasks

Mechanical Workshop: The mechanical workshop has two major parts one for static mechanical and for rotatory mechanical. All the mechanical related tasks are performed in the mechanical workshop. The item to be repaired is de assembled from the plant; its backup is placed in the operation, the faulty part is brought to the workshop and repaired. Mechanical workshop also has the offices for the supervisors and also contains store where more than 3 thousands different parts are kept. Mechanical workshop also have regions for manufacturing the spare part if it is not available, there is also region for welding. The welding done at mechanical workshop is not any normal welding but in fact it is very high pressure and special kind of welding done by specialist. There is also region for testing the most important part of the process industry i.e. valves. Specialized equipment’s are present to check the values of all types i.e. electrical, pneumatic etc.

The Section Where I Was Assigned:

I was assigned with the auto control & electrical section of the maintenance department on basis of

my study course i.e. electronics engineering. A complete schedule was provided to me for the

entire 4 week training at the QAPCO complex. One the basis of course of studies I am undertaking

i.e. electronics engineering I was assigned with the Auto control & electrical section of the

maintenance department.

Page 4

Auto control & electrical section: As the name indicates auto control & electrical section is responsible for the automation and the

electrical related work at the plants. Like mechanical section there is also workshop for the auto

control & electrical section.

Auto control & Electrical workshop: The workshop contains the electrical diagrams for the entire plant. There is hall where the shift teams sits and discuss the problems and task they have to undertake. There is also space for dcs/ PLC supervisors along with other supervisors in separate region. Also there is room where the instruments required for auto control are kept in locker. The keys of the lockers are with the supervisors. The workshop also contains the instrument for calibrating different gauges and other transmitters present in the field.

Auto control & Electrical section is further broadly divided into two broad categories:

Auto control or Automation

Electrical

Electrical: Electrical part is responsible for the maintenance of electrical network and electrical related devices

such as motors, compressors, compressors etc. at the QAPCO complex. QAPCO is a big complex, so

electrical section is divided further into sub sections. These sub sections are divided based on the

plants and areas that are:

Logistics

QATOFIN

LDPE 1/2

LDPE 3

Ethylene

Utilities

QAPCO Electrical Network consist of 5 gas turbines generators, level at 33KV, and one Kahramaa

incomes, which is stepped down from 132 KV to 33KV.

Each gas turbine has a capacity of 25 MW and are running synchronous with the Kahramaa income

so that if one fail other can take over.

Page 5

Logistics: Logistics is responsible for the handling of the product produced by the production plants at

QAPCO. Products produced at QAPCO are low density polyethylene, ethylene gas and sulphur.

Other than these it is also responsible for loading QVC product that caustic soda, VCM and EDC to

the ships. There is also a salt belt required for unloading salt again for QVC.

Only LDPE is in solid form and packed in bags while other are loaded directly to the ships( sulphur

through belt and EDC, VCM, Caustic soda and ethylene through loading arm).

Logistics also have the two sulphur storage unit i.e. unit 27 & 28, and bagging lines for packing

LDPE.

There are three bagging lines C, D and E. LDPE is packed in form of 25KG, 5 packs per layer and 12

layers per pellet. Bags come in role, and a part of bagging line is assigned as bag making section.

Then come the bag filling section where the bags are filled with 25 kg of product, with margin of

25g. A weight and a metal detector is also present on the bagging lines. Then these bags are sent to

palletizing section where they are packed in form of pallets. The motors at palletizing are driven by

variable speed drives such as MOVITRAC & MOVIDRIVE by SEW and brakes to provide controlled

acceleration and deceleration.

Bagging lines C & D are controlled by Siemens S5 PLC and older model of MOVITRAC which are

programmable by console only.

Bagging line E is controlled by Siemens S7 PLC and with MOVITRAC which can be programmed

through laptop.

From here the pallets go the warehouse. Jetty team packs these pallets into the containers. Crane

team takes container from stuffing area to the loading area. Crane team is equipped with four

carrier cranes.

Then come the part of loading and unloading of product from the ships. For loading there three

cranes:

1. Reggiane: Completely electricity based crane. Controlled by Siemens S5 PLC. Moves on track

only. Takes input of 3.3KV through slip rings to the transformer. An Italian crane

2. Lieberr: Works on diesel. All the motions are based on hydraulic motors. The controlling PLC

for Lieberr is Letronic GE. A German made crane with wheels for to and fro motion.

3. Gottwald: a new crane still under commissioning process. Works on a diesel generator and

an electric input during stand by for cooling systems to run. Based Siemens S7 PLC for

control. Two motions are based on hydraulic motors while two motions are based on dc

motors. 12 cylinder diesel generator runs the crane producing a power of 630KVA. A

German made crane with wheels for to and fro motion.

Page 6

For liquids there are loading arms having many kinds of proximity sensors which imposes limit on its

motions.

There is also a salt discharging conveyor for salt imported for QVC plant. Salt belt has two 2

controlling cpu. 1 cpu is for back up.

There are also three hoppers for this salt conveyor. Each hoper has a two vibrator motors.

There are two sulphur storage units, where the granulated sulphur is stored until it is shipped

through Wharf conveyor.

Site Visit:

In logistics first visit was at bagging section. There I saw the working of D and E line. C line

was out of service as one of its motor was having winding fault. Also seen the controlling

PLC for both line as well as variable speed drives. Line E had almost double the capacity then

line C & D, as line E processes two bags during pelletizing part where they process only one.

After that went to observe the two warehouses and jetty area.

Next visit was at the loading area for liquids, salt and sulphur. Observed the different

sensors for the loading arms. For each product there where two loading arms except

ethylene which has two, one for vapors and other for liquid. Also observed the working of

conveyor and hoppers, as a ship from India was docked in unloading salt. One of the

hoppers out of order and being repaired. Went on two see the controls for salt conveyor,

sulphur loader and sulphur storage unit 27.

Lastly went two the container loading area. Here the carrier cranes position the container

for loading at the ship. At that time Gottwald crane was being commissioned and logistics

team where check listing its electrical parameters. Observed different sensors around the

crane, its control room, motor for its different motion spreader and the generator room.

Similarly went to the Reggiane crane also, which as its track made for its movement and gets

its electric supply through slip rings so that cables do not brake due twisting caused by

movement of the crane.

QATOFIN/LLDPE:

QATOFIN is a joint venture between QAPCO (63%), Total Petrochemical of France (36%) and Qatar

Petroleum (1%) and its designed to produce 450000 metric ton per year of linear low density

polyethylene (LLDPE).

Electrical network for LLDPE is different from Logistics and LDPE1/2. It receives supply from

Kahramaa at 132KV. Substation of LLDPE also supply to the new LDPE 3 plant at QAPCO.

The supply from Kahramaa is stepped down to 33 KV, used at QAPCO, through two feeders (oil

forced air forced transformers). The output buses from two feeders are connected through coupler

which is normally closed so that if one feeder goes down other can take its load.

Then it is further stepped down two 6.6KV, 690V and 380V.

The two main feeders have auto tap which adjusts the tap position automatically without going

offline.

6.6 KV supply is used to provide power to two extruder motors at QATOFIN plant (14 MW and 4.2

NW induction motors). To improve power factor capacitor banks are provided with each of these

two large motors.

Since there are no synchronous motors present at the QATOFIN plant two separate capacitors

banks present for rest of the entire QATOFIN electrical network.

Also the 6.6KV supply is then stepped up to 11KV and supplied back to Kahramaa, which requires it

for is some uses. Variable speed drives are used to run motors at plant controlled through DCS.

There is also diesel generator for emergency producing 690 V. Diesel engines start automatically

when the power fails. After when the power is restored a special type of meter which checks

voltage, frequency and phase of income and generator supply closes the bus tie between the two

then it senses the two input are synchronized. The diesel generator is then manually turned off.

The emergency generator is tested on monthly bases.

Also there are different UPS are installed for critical parts of the plants. A three phase supply is

converted to dc through rectifier and sent to battery. For some motors direct dc is applied and for

some the output is again converted to AC through invertors. The UPS can run the critical load for

around 20 hours.

Site Visit:

Went to the QAROFIN substation. Substation was divided into two parts, high voltage and

low voltage. High voltage deals with voltage at 33KV and 6.6KV. One of the main feeders

Page 8

from Kahramaa was under maintenance so other feeder was taking the load of the entire

plant. Substation was very compact as compared to other substation in the QAPCO as it uses

new technology Gas insulated systems insulated by SF6 gas.

Observed the different capacitors banks and saw the control for two big induction motors.

Also the automatics tap changer for the main feeders

Then at low voltages side software was used to link the PDS. Observed the drive monitoring

circuits for motor at QATOFIN. Also the VSD and UPS cabinet. AT plant firstly observed the

two big motors then other pumps and motors installed. On way back saw the main feeders

and other small transformers. Finally the battery room where batteries for UPS are kept.

Each cell of battery was 1.2V. they were connected in series two required voltage output i.e.

40V, 220V etc.

LDPE3:

LDPE 3 is the new plant at QAPCO which is still under commissioning process.

LDPE 3 has four incomers from LLDPE sub station, which receives its supply from Kahramaa. The

voltages level are at 11 KV, 6.6 KV, 690 V and 400 V.

Three big motors i.e. hyper compressor (25 MW), primary compressor (5 MW), extruder (3 MW)

are running from 11 KV supply.

LDPE 3 has latest technology installed including Sepam 80 protection relays etc. which are

controlled through SCADA while power is controlled by PDCS. Each relay has an IP address and is

connected to central control room through fiber optic cable.

LDPE1/2: For LDPE1/2 there are two 33KV to 3.3Kv incomers from Utilities. Voltages levels which are used are

3.3KV and 400V.

3.3KV is required by the main motors that are extruder and compressors, while 400V is required by

other small motors installed at the plant.

There are also two large motors i.e. 17MW & 17.9 MW, which works on 33KV. They are started

through gas turbines installed at logistics.

There is also a Diesel generator for emergency which checked on monthly bases. Apart from it UPS

is also present constant supply to critical equipment.

Page 9

Ethylene: There are 3 incomers from utilities (33KV to 3.3KV). then the voltages is further stepped down to

400V required by small motors.

In Ethylene Flywheel energy storage system is installed, which convert mechanical energy to

electrical energy. It can take load for only 30 sec, during which emergency diesel generator can be

started.

This ensures that no outage of power during emergencies.

Utilities: In utilities there are 5 gas turbines generators, producing 25MVA each. There is also line from

Kahramaa which in synchronous mode with gas turbines.

Turbines generators produce voltage at 11KV, which is then stepped up to 33KV. These generators

are also used for the startup of the hyper compressors. Other voltages level used are 3.3KV and

400V required by other motors at utilities

5 boilers are also present in utilities to provide steam to other plants.

There are 5 gas compressors and 2 nitrogen units. Apart from these salt desalination and sea water

pumps are also present in utilities.

Page 10

Auto Control: Auto Control is responsible for all the control devices installed at the QAPCO complex. Control

devices include field transmitters, control values etc. Since all the plants at QAPCO are controlled

automatically through control room, responsibility on auto control people increases greatly and

lower the burden on auto control people, it is further divided into sub sections. Following are the

sub sections of the Auto control section:

Field Instrumentation

Fire & Gas

Analyzers

PLC/DCS

Auto control is also called as Automation

All of the above listed sections of auto control are responsible for the control loops at the QAPCO

plants, through which operator controls the output of any plant. Below is detailed description of

each individual sub section:

Field Instrumentation: In Field Instrumentation include transmitters for four basic physical quantities:

Pressure

Flow (works on principle of differential pressure on two plates)

temperature (thermocouple, RTD)

level (differential pressure type, displacement type)

Apart from these, field instrumentation is also responsible for the pneumatic control value, other

transducers and convertors in the field.

Since there is a lot of instrumentation even at a single plant, field instrumentation personal are

divided into teams, each team responsible for their plant. Teaming for field instrumentation section

is as follows:

Utilities

Ethylene

LDPE1/2

LDPE3

QATOFIN

Page 11

LOGISTICS

Each team is responsible for the field instrumentation at their defined area. Field instrumentation

teams are responsible for maintenance for transmitters and even their calibration. Even Pneumatic

operated valves are also their responsibility.

Site visit:

In automation section firstly I was assigned with Field instrumentation team of utilities. On

the start of day I accompanied the technician to new boiler installed at QAPCO. One of the

differential pressure transmitters had to be recalibrated. The transmitter will be calibrated

by a device called field communication. The probes of communicator are connected at the

points, in parallel, where the transmitter gets its power supply. It then develops the soft link

with the transmitter and gives values on its screen, through which it can be calibrated. For

manual transmitters, it is calibrated through ammeter with 0% at 4mA and 100% at 20mA.

After this observed the different instrumentation at five boilers and 5 gas turbines installed

at utilities plant

In section of field instrumentation my second visit was with the team for ethylene. Firstly

accompanied them to the unit 26, sulphur processing unit. Production team complained

about the level transmitter not controlling the flow values from NGL and QP refinery. On

testing the transmitter with field communicator it was found the transmitter was working

perfectly and controlling one pneumatic value on NGL line. The other value on the QP

refinery line, motor operated value was out of order. Then they accompanied me to

ethylene plant. There I observed different transmitters and values installed on the plant.

EP1 is an old plant and there can be found transducer with only primary element with ni

transmitters. EP2 is a new plant with latest transducers with transmitters and pneumatic

values, with I2P converters (current to pressures converter which converts standard DCS

current value to standard pressure value, to operate the value).

Fire & Gas: Fire & gas team under the section of Auto control are responsible for the instruments related for

the detection of fire and gas leaks. These instruments include the transmitters for detection of

oxygen deficiency, hydrocarbon leak, smoke detector, heat detectors, flame detectors etc. They are

installed all around the QAPCO depending upon surrounding requirement. They also include gas

detectors for gas which toxic for human life.

Apart from these sensors and transmitters Fire & Gas team are also responsible for all other

equipment installed for emergency at the QAPCO. These include the public address system, sirens

and CCTV camera installed at critical locations in QAPCO plants.

Page 12

Fire & Gas team also maintains the gas detectors installed at the fence with QVC plant, as toxic

gases are present at QVC plant.

All the fire and Gas emergencies are coordinated through Fire & gas control room. Fire & gas

control also has incoming line for fire emergency telephone installed at different location in

QAPCO. Control also has a public address system for emergencies and communication system with

its team member in QAPCO and also at QVC, as QVC does not have Fire & Gas team.

Other than this one panel is of fire & gas is also installed with other control panels for each plant,

indicating fire & gas emergencies at that plant.

Site visit:

I assigned with a team member of the fire& gas who was on his way to the LDPE3 catalyst

storage room where one oxygen deficiency meter was giving alarm. On reaching the catalyst

room we found that the transmitter was installed in a room where temperature was

maintained at 10 0C. On checking the transmitter we find that it out of calibration. So it was

re calibrated using nitrogen cylinder providing 0% oxygen and atmosphere providing 20.9%.

When level of oxygen falls below 19% it gives alarm. I also observed the smoke sensors

installed in the catalyst room. In each room 4 smoke sensors where installed, if any two of

them are activated, alarmed are sounded and water is released. For LDPE1/2 catalyst room

one heat sensors were installed. It consisted of wire which melts on high temperature,

giving alarm and releasing water in the catalyst storage area.

I went on to visit Fire & Gas main control room and observed their working. Also learned

about their fire telephone, CCTV camera and public address system. Fire & Gas of QAPCO

are also responsible for Fire & Gas emergencies of QVC and maintains a good combination

with them.

I was again assigned with other member of Fire & Gas who was on his way to check a

hydrocarbon detector located at top of one off silo at LDPE3 plant. On reaching the top silo

after performing some test on the analyzer for hydrocarbon, it was found that vacuum

pump which is used to suck up the hydrocarbon up to the detector was faulty. The part was

currently not available so it would have to be replaced the next day.

Finally I went to Central Control Room to observe the control system for CCTV cameras

installed at critical locations at QAPCO. Different plants where given different code to get

access to the cameras installed at that plant as 61, 62, 63 and 64.

Page 13

Analyzers: Analyzers team is responsible for more approximately 275 analyzers installed all over QAPCO.

Analyzers are also transmitters that provide reading to the operator for controlling the chemical

process taking place. Analyzers does not include four basic transmitters i.e. flow, pressure, level and

temperature.

In QAPCO analyzers are divided into two main categories:

Gas Analyzers

Liquid Analyzers

Liquid analyzers include pH analyzer, conductivity analyzer etc.

Gas analyzer include moisture analyzer, gas chromatograph analyzer etc.

Analyzers are related to the chemistry of the chemical process. They are essential part because

operators controls the process based on these reading.

Site visit:

• I assigned with a team member to the visit to the LDPE3 plant where one pH analyzer

was providing faulty reading. On arriving LDPE3 team first washed the sensing element

and then recalibrated the analyzer through buffers

Then I went on to observe the different analyzer across the QAPCO. All observed the Gas

Chromatograph and had a detailed discussion on the working principle of this analyzer

DCS/PLC: Distributed control system (DCS) and Programmable Logic Controller (PLC) are the main controlling

element in the control room. They take the reading from the transmitter and controls the values

based on the configuration. In QAPCO, DCS of Honeywell is present while PLCs of different

companies can be found.

DCS/PLC team is further divided into two groups

• Olefins

• Polyolefin

Olefins teams are responsible for Utilities & Ethylene plant

Polyolefin are responsible for LDPE1/2, LDPE3 & QATOFIN.

Page 14

DCS/PLC teams are responsible for troubleshooting for the problems originating related to the

control system. They also modify the logic as per requirement of the production team

In Olefins Honeywell’s AM & HPM modules are present, based on coaxial cable, with TPS operating

system for the controller. But TPS is being replaced by new graphical operating system of

Honeywell that is known as Experion.

In Polyolefin LDPE3 and QATOFIN have the recent of Honeywell DCS known as C200. C200 based on

Ethernet cable. While LDPE1/2 control is on old AM & HPM modules, but operating system for it

has already been shifted to latest Experion.

Apart from these PLC are also present and control the critical machine in plant. they are connected

to DCS to for an complete control network

Site Visit:

• I went to the DCS to local control rooms of the ethylene & utilities plant where I

observed the DCS and PLC cabinets. I also observed the different configuration for the

DCS and different PLCs

• Then I also went to the observe the DCS cabinet for new QATOFIN & LDPE3 plant
