Abstract
In the separation of low boiling gases such as ethane or propane and heavier from a gas stream such as natural gas, a first portion of the feed is heat exchanged with an overhead from a downstream stripper column, such as a demethanizer, a second portion is heat exchanged with a stream from a lower portion of said stripper column, and these two portions passed as separate streams to a separator-contactor. The first stream is added at a point above the second. This results in an increase in the recovery of liquid products.
