Abstract:
The present invention relates to a method and system for producing liquefied natural gas (LNG) from a stream of pressurized natural gas which involves a combination of mechanical refrigeration.

Claim (Index 1):
A natural gas liquefier system, comprising:\n a) a natural gas inlet in fluid communication to a source of natural gas; b) a liquid nitrogen inlet in fluid communication to a source of liquid nitrogen; c) at least one refrigerant inlet in fluid communication to a source of gaseous refrigerant fluid; d) at least one gaseous refrigerant outlet at a lower pressure than the refrigerant inlet in fluid communication to a device to receive the lower pressure refrigerant fluid; e) a liquefier module in fluid communication to receive the natural gas, liquid nitrogen, inlet and outlet refrigerant flows which also includes at least one work expansion device; f) at least one work expansion device which receives the flow of inlet refrigerant and discharges a flow of a reduce temperature refrigerant at a reduced pressure, wherein the inlet flow to the at least one work expansion device may or may not be pre-cooled within the liquefier module to a sub-ambient temperature; and g) said liquefier module receiving the reduced temperature and pressure refrigerant fluid is then warmed where it is processed and discharged from the liquefier module as the gaseous refrigerant outlet; and liquefied natural gas output coupled to the liquefier module.
