Process to separate hydrocarbons from gas streams

Patent ·
OSTI ID:5052099
A process is described for the separation of specific C/sub 2/ to C/sub 6/ hydrocarbons from a gaseous feed stream containing C/sub 1/ to C/sub 6/-plus hydrocarbons. The feed stream enters an absorber and is first contacted by a primary lean liquid which is a portion of the bottoms product of the stripping column to which the rich absorber liquid is charged. The primary lean liquid contains the specific hydrocarbons which it is desired to separate from the feed stream. The feed stream is then contacted by a secondary lean liquid which does not contain these hydrocarbons and which is produced by fractionating a second portion of the stripper bottoms.
