METHOD FOR LIQUEFACTION OF HYDROCARBON-RICH GAS STREAM Russian patent published in 2003 - IPC

Abstract RU 2212601 C2

FIELD: gas liquefaction. SUBSTANCE: method involves providing of indirect heat-exchanging with coolants into cascade-type cycles using coolant mixtures. Each cascade includes at least three cycles using coolant mixtures of various compositions. First cycle is adapted for precooling, second cycle is used for liquefaction, third cycle is used for sub-cooling of liquefiable gas. EFFECT: reduced power consumption and decreased capital investment. 8 cl, 5 dwg
