ABSTRACT:
A process is shown for producing liquefied natural gas from a pressurized natural feed stream. The feed stream is introduced into heat exchange contact with a mechanical refrigeration cycle to cool the feed stream to a first cooling temperature. At least a portion of the feed stream is passed through a turboexpander cycle to provide auxiliary refrigeration for the mechanical refrigeration cycle to thereby cool the feed stream to a second, relatively lower cooling temperature.
