Filling
or Emptying
The following filling instructions are clearly indicated on the inside
of door.
A. Opening
1. Bleed off any pressure in the manifolds
by opening and closing of valves 'J' & 'K'
2. Remove caps 'G' & 'H'
3. Couple 'LIQUID' & 'GAS' hose couplers
4. Pull out handle 'A' to open excess flow
valves 'E' & 'F'
5. Operate 'C' & 'D' handwheels to open
the globe valves slowly
B. Closing
1. Push back handle 'A' valves will close
automatically
2. Operate 'C' & 'D' handwheels to close
the valves
3. Disconnect 'LIQUID' & 'GAS' hose couplers
4. Screw on caps 'G' & 'H'
DANGER
Nitrogen is lethal to human life. If a tank is nitrogen purged nobody
should attempt to enter this tank unless it has been vented and tested
before. nitrogen will cause collapse and death within minutes.
|
|
Before any filling operations:
Make sure that the tank is empty and gas-free.
Connect the earth wire to the earth points provided on the tank frame.
When filling has been completed and/or filling pipes have been removed:
Disconnect the earth wire;
Apply TIR seals to all sealing points. |

Filling
and Emptying with Product |
|
|
Open the valve cabinet doors X and Y |

REMOTE CONTROL
The remote control cable V should be hooked onto ring N. In an emergency
a sharp pull on the remote cable will automatically close off the excess
flow valves E and F.

FILLING
FOR TRANSPORT UNDER INERT GAS |
|
|
Follow the instructions
under Filling.
A. PURGING WITH NITROGEN:
- Always fill through the liquid line and bleed off through the gas line;
- Dry Nitrogen (dew point -20°C) should be used for transport under
inert gas. The main reason for this is to prevent any oxidization of the
bare carbon steel on the inside of the tank;
- The most accurate procedure during purging is to use an Oxygen % metre
at the gas line outlet. Purging with nitrogen should continue until the
Oxygen content registers less than 2%. If an Oxygen % metre is not available,
the following can be used as a guideline:- Duration of bleeding before
closure of gas line: approximately 10-12 min; |
|
- Care should be taken
that liquid Nitrogen does not enter the gastank (indicated by freezing
of the nitrogen feed line);
- To prevent this the Nitrogen volume flow should be controlled in order
not to overstep the Nitrogen storage tank evaporator capacity. Once the
oxygen has been displaced, close off the gas phase globe valve D and allow
the pressure to build up to between 1 and 2 bar. Once this pressure is
reached, close the excess flow valves by pushing back handle A following
the instructions for closing under Filling or Emptying. |
