Abstract
Disclosed herein is a membrane separation apparatus that includes an integrated filter element and a membrane element housed within a single vessel. The vessel is configured to allow liquids to be trapped and removed from the vessel, and gases to flow to and through the membrane element. The apparatus is useful in the conditioning of fuel gas to separate methane from C2+ hydrocarbons.
Claims20
