Abstract
A process and apparatus for separating the components of a hydrocarbon gas feed stream is disclosed. A multi-component hydrocarbon gas feed stream is contacted with a solvent in an absorber to produce a first overhead stream that is enriched in a first component and a rich solvent bottoms stream that is enriched a second component. The rich solvent bottoms stream is flash vaporized to recover the second component as a second overhead stream and to produce a lean solvent stream that is returned to the absorber. During the flash vaporization process, the rich solvent bottoms stream is contacted with a stripping gas that is a portion of the first overhead stream. This stripping process enhances the recovery of the second component during the flash vaporization.
