the VIE tank

Result:

Status: Completed on 23rd June 2016

Phase 3: Welding and to connect the PBC (Pressure Building Coil) onto the tank

Date of commencement: 24 to 25th June 2016 (Friday to Saturday)

Agenda:

- To fabricate two square flange with gasket for the PBC unit

- To weld a 1” schedule 40 pipe to both of the square flanges

- To thread 1” NPT pipe connection for the Pressure Build-up Regulator (2 of them in total)

- To weld the remaining socket weld ball valve to connect the PBC from V7 to V13

- To build sufficient base support to withstand the weight of both the PBC and regulator

Result:

Status: Completed on 25th June 2016

Phase 4: To clean and repaint the tank

Date of commencement: 28th June 2016 (Tuesday)

Agenda:

- To remove the existing SIG symbol

- To clean the dust from the tank

- To repaint the tank

Result:

Status: Completed on 2nd July 2016

Phase 5: To fill liquid carbon dioxide (20 tonnes) into the VIE tank

Date of commencement: 29th June 2016 (Friday)

Agenda:

- To fill 20 tonnes of LCO into the VIE tank (by Cyromaster and monitored by Gopa)

- To analyze the carbon dioxide purity after liquid filling (by QA Nilai, Mr Lai)

- To train Synergy personnel onto the refilling process and pressure building coil (by Gopa)

Result:

Liquid level after filling – 17 tonnes of CO2

VIE Pressure – 19 bar

Gas purity analysis – 99.6 to 99.7 %

Refilling training by Gopa to Synergy personnel – Done, however need more training onto the

technical stuff

Status: Completed on 29th July 2016

5.0 Procedure (For refilling carbon dioxide cylinder)

Pre-operation

5.1 Ensure that the pressure within the storage tank at 15 bar and above (18 bar to

20 barg would be the best). If the pressure is lower than 15 bar, then operator

can use the Pressure Building Coil (PBC) to increase the tank pressure to 19

bar (refer to Section 6.0).

5.2 Ensure that the P1100 is filled with oil (where the sight glass is full can be

seen).

5.3 Ensure that all valves within the refilling station has been closed or shut.

Operation

It is important to cool down the pump before starting it and appropriate pressurization

procedures should be followed to ensure that no dry ice formation (solid carbon

dioxide).

5.3 First, open the pump return valve (V-4) as shown in the appendix figure to

allow pressurization of the line to be taken place. Then, open switch the 3-way

valve (V-3) where the flow can be directed from pump to storage tank.

5.4 After the pressurization process, open the liquid supply line (V-1) to begin the

cooling process. The cooling process will take around 10 to 15 minutes,

however, the process itself can be accelerated by opening the vent/cooling

valve (V-2) until liquid phase can be seen flowing out and the pump cylinder

is icing. When the cooling is sufficient, close the vent valve (V-2) and start the

pump. (* Make sure that the 3-way valve is flowing from the pump to the

storage tank to prevent overpressure).

5.5 With the pump is running, place both gas cylinders onto the weighing

machines. Then, connect the flex hoses to both of the cylinders and open the

cylinder head valve on both. (* Always remember and ensure that the cylinder

valve is opened to prevent over-pressure within the line which can be

dangerous.)

5.6 Then, turn the 3-way valve (V-3) to allow the flow direction coming from the

pump to the refilling line and open the line valve (V-5) to begin the filling

process. (* Make sure that the line valve at V-6 is closed.)

5.7 After the refilling process is done where the weight has reaches its appropriate

capacity, close the line valve (V-5) and open the line valve (V-6) so the other

gas cylinder can be filled. While waiting, remove the flex hose on the first gas

cylinder and remove it from the weighting machine. The new gas cylinder

then can be put onto the weighing machine waiting to be refilled, the process

can be repeated from 5.4 to continue the refilling process.

Post-operation

5.9 To shut the refilling station, first close all the line valve (V-5) and (V-6) and

turn the 3-way valve to the direction flowing from pump to storage tank.

5.10 Then only proceed to stop the pump and close both valves at (V-1) and (V-4)

to ensure no more liquid and vapour is flowing into the line. Finally, vent the

remaining liquid and gas by opening the vent valve (V-2) until the remaining

pressure dropped to zero.

6.0 Procedure (For building tank pressure)

To build the tank pressure

6.1 If the tank pressure is lower than 15 bar, operators can build the tank pressure

itself by following the procedures below. First, ensure that the valves from

Bottom Fill and Gas Balancer are closed.

6.2 Then slowly open the valve at (V-7) and wait for a few minutes, this will

allow time for the liquid to vaporize into gas with high pressure.

6.3 Open the valve at (V-8) and (V-9) to allow the high pressure gas to flow into

the tank to increase the tank pressure. This process might takes around 10

minutes and more. If the pressure increased to 18 bar, then proceed to close

valve at (V-7), (V-8) and (V-9). The operators can then proceed to refill for

the carbon dioxide cylinders.
