Abstract
A process for producing liquefied natural gas from a high pressure hydrocarbon feedstock is shown. In this process, the feedstock is isentropically expanded and distilled at a pressure lower than the critical pressure to form an overhead rich in methane and a bottom fraction. The methane rich overhead is compressed utilizing the energy obtained from the expansion and then the compressed overhead is liquefied in a refrigeration cycle.
