The PEEK-SEP membrane platform can operate in condensing service and thus offers an intrinsically stable platform to separate hydrocarbon fluids as well as traces of water, methanol, etc. through the selection of the appropriate separation membrane. The low-pressure membrane stream may be recycled upstream of the booster compressor to knock out the liquids for separation and treatment.
Natural gas liquids (NGLs) stabilization requires removal of volatile fractions of hydrocarbons from NGLs. These typically include ethane, propane and butane. Air Liquide Advanced Separations' (ALaS) PEEK-SEP membranes are well suited for this purpose in that they can separate the volatile fractions.
