Abstract
An apparatus (10) for drying a wet stream of hydrocarbon gas includes a plurality of hollow fiber membranes (40) for osmotically imbibing water from a wet gas stream flowing on one side (48) of the membranes and forming a dried retentate stream and diffusing a water permeate to the second side (46) thereof and preventing imbibing and diffusion of hydrocarbon and halogenated hydrocarbons therethrough. The water permeate is removed from the cores (44) of the membranes (40) and the dried hydrocarbon and halogenated hydrocarbon retentate stream is removed from the second side (48) of the membranes (40). A portion of the dried retentate stream is recirculated as the sweep stream through cores (44) of the membranes in a closed fluid flow circuit.
