Abstract
An improved process for separating hydrogen from hydrocarbons. The process includes a pressure swing adsorption step, a compression/cooling step and a membrane separation step. The membrane step uses a rubbery polymeric membrane selective for all C1-C6 hydrocarbons over hydrogen. The process can produce three products: a high-purity hydrogen stream, an LPG stream and a light hydrocarbon fuel gas stream.
