Abstract: A method for liquefying natural gas comprises: condensing at least a portion of a natural gas feed stream to produce a partially condensed stream; and separating the partially condensed stream into a first liquid fraction and a first vapour fraction; wherein the first liquid fraction comprises liquefied natural gas.

Abstract: An improved process for recovery of liquefied petroleum gas from a raw natural gas feed stream, capable of achieving ultra high propane recovery yields, thereby separating substantially all of the propane and heavier hydrocarbon components from a predominantly methane and ethane feed gas stream. The process includes steps to liquefy all of the propane and heavier components and part of the methane and ethane components by cooling, condensing, and absorption. The residual feed gas containing the methane and ethane components, being the final gaseous product stream. The liquefied portion of the feed is separated and then fractionated in a distilling unit to produce a propane and heavier product stream. The distilling unit overhead vapors are cooled and condensed in two steps to provide reflux for the top of the deethanizer and for the feed gas absorption.
