METHOD AND APPARATUS FOR LIQUEFYING HYDROCARBON STREAMS

摘要

A method of cooling at least two hydrocarbon streams such as natural gas, the method at least comprising the steps of : (a) providing at least first and second hydrocarbon streams (20, 20a); (b) passing the first hydrocarbon strea (20) through one or more first heat exchangers (12, 14) to provide a first cooled hydrocarbon stream (30); and (c) passing the second hydrocarbon stream (20a) through one or more second heat exchangers (12a, 14a) to provide a second cooled hydrocarbon stream (30a); wherein a refrigerant circuit (100) provides cooling to the first heat exchanger (s) (12, 14) and the second heat exchanger (s) (12a, 14a).
