An apparatus for separating water from a water and hydrocarbon mixture and water from a water and halogenated hydrocarbon mixture includes membranes consisting essentially of nonporous self-supported hollow fibers of cuproammonium cellulose, the membranes including inner and outer surfaces, and a conduit for conducting a stream of the mixture of hydrocarbon and water into contact with one of the membranes. The membranes imbibe water from the stream to diffuse to the other side of the membranes. The water is then removed from the other side of the membrane.

In a method for drying a wet stream of hydrocarbon gas by the use of a hollow fiber membrane while producing a hydrocarbon free water permeate, the steps of; employing as a membrane nonporous self-supported hollow fibers of cuproammonium cellulose, conducting the wet hydrocarbon gas stream into contact with the outside of the fibers, osmotically imbibing water independently of convective pressure of the stream of gas from the stream into the fibers while preventing imbibing or permeation of hydrocarbons; diffusing the water free of hydrocarbons to the bores of the fibers, removing the imbibed water free of hydrocarbons from inside the bores, and removing the dry gas from outside of the membrane.
