CARBON DIOXIDE LIQUEFACTION PLANT Russian patent published in 2010 - IPC F25J1/00 

FIELD: process engineering.

SUBSTANCE: proposed plant comprises radial-flow compressor, pump, steam generator, condenser-evaporator and absorption water-ammonia refrigerator. Proposed pre-cooled carbon dioxide liquefaction process comprises two-stage compression of carbon dioxide in aforesaid radial-flow compressor and pump and chill of aforesaid absorption water-ammonia refrigerator, and steam production in steam generator. The latter process exploits heat resulted from compression of carbon dioxide in aforesaid radial-flow compressor to be fed into absorption water-ammonia refrigerator.

EFFECT: reduced power consumption.
