Cryogenic distillation to produce liquid gas products
AGA Germany commissioned Costain to develop a design for cryogenic distillation to produce liquid oxygen, liquid nitrogen and liquid argon.
Liquid oxygen, liquid nitrogen and liquid argon
Low energy consumption
We used our process engineering expertise to achieve the desired products with low energy consumption and a high level of safety. The technology used was cryogenic distillation and the process incorporated high efficiency machinery, low pressure drop and excellent heat integration.
Costain plants give high recovery of all three products with near total recovery of liquid oxygen and liquid argon. The quantity of liquid nitrogen is a customer choice with the balance of nitrogen produced as gas.
