The CGR Plant utilises liquid nitrogen as a heat exchange fluid. In the heat exchange process, hydrocarbon gases are liquified close to the freezing point. Liquid nitrogen is vaporised and can be used as purge gas of containment systems. Thus, a cargo system can be purged with nitrogen, while all remaining gas atmosphere is simultaneously recovered without emissions to the atmosphere. 

An intermediate cooling circuit ensures that temperatures does not fall below the freezing points of the hydrocarbon gases.

"The application of an integrated heat transfer fluid makes this system truly efficient and flexible and allows recovery of a wide variety of VOCs."
