01 | LNG storage tank
The LNG storage tank is a horizontal, cylindrical, doublewalled container, which is vacuum-insulated using perlite. The inner container is made from stainless steel, and the outer container from carbon steel.
02 | Vaporisers (pressure build-up and saturation vaporisers)
Pipes with star-shaped aluminium fins are attached along either side of the container, to act as vaporisers. These provide pressure build-up when the storage tank is filled and saturation when LNG is withdrawn via the dispenser.
03 | LNG pump
The built-in immersion pump is permanently submerged in the LNG.
04 | Air compressor (piping)
The air compressor and drier are built in to an ISO standard frame with the required process valves and piped connections.
05 | Nitrogen tank (LIN)
When necessary, liquid nitrogen is used to cool stored LNG; it is stored in a separate tank.
06 | Dispensing pump (dispenser)
LNG is withdrawn via the dispensing pump. Withdrawal volume is measured using an integrated mass flow meter.
07 | Customer-activated terminal
The customer-activated terminal opens the dispenser, allowing truck drivers to refuel using a special card.
08 | Electrical container
Electrical switchgear and the control system are built into a separate container.
