Abstract

A process for the recovery of LPG from liquefied natural gas (LNG) is disclosed. The LNG feed stream is subjected to a two stage separation process where the bottoms from the first stage separation containing C2+ hydrocarbons is split into three portions, one portion is fed directly to the top of the second separation stage as a reflux stream, a second portion is warmed and partially vaporized by cross heat exchange with overhead vapors from the second separation stage before being fed to the middle of this second separation stage, and the third portion is heated and vaporized by cross heat exchange with bottom liquids from the second separation stage prior to being fed into the bottom of this same separation stage.
