Abstract: Cryogenic liquefying/refrigerating method and system, wherein temperature of gas-to-be-liquefied at the inlet of the compressor for compressing the gas is reduced by cooling the gas discharged from the compressor using a high-efficiency chemical refrigerating machine and vapor compression refrigerating machine before the gas is introduced to a multiple stage heat exchanger thereby reducing power input to the compressor and improving liquefying/refrigerating efficiency. Gas-to-be-liquefied compressed by a compressor is cooled by aftercooler, and further cooled by an adsorption refrigerating machine which utilizes waste heat generated in the compressor and by an ammonia refrigerating machine 40, then the high pressure gas is introduced to a multiple-stage heat exchanger where it is cooled by low pressure low temperature gas separated from a mixture of liquid and gas generated by adiabatically expanding the high pressure gas through an expansion valve 30 and returning to the compressor, and a portion of the high pressure gas is expanded adiabatically by expansion turbines in mid-course of flowing of the high pressure gas through the stages of the heat exchanger to be joined with the low pressure low temperature gas returning to the compressor.

Abstract: A support structure that is either floatable or otherwise adapted to be disposed in an offshore location at least partially above sea level. A natural gas liquefaction system is located on or in the support structure and has a series of heat exchangers for cooling the natural gas in a countercurrent heat exchange relationship with a refrigerant. One or more compressors compress the refrigerant which is divided into two separate streams. Each stream is fed to a liquid expansion turbine where it is isentropically expanded. The expanded streams of refrigerant are then fed to the cool end of one of the heat exchangers.
