ABSTRACT:
A process and apparatus for liquefying a natural gas, having a pressure above about 800 psig, in which the natural gas is introduced into an expander which operates to reduce the pressure of the natural gas and extract work from the expansion of the natural gas during the pressure reduction so that the resulting effluent from the expander can be cooled to sequentially lower temperatures by passing the gas through a plurality of cooling stages, in indirect heat exchange with at least one refrigerant, until the gas is substantially completely condensed in the last of the cooling stages.
