Abstract: The invention involves a process for treating a gas stream from a hydroprocessor that contains hydrogen, methane and C2+ hydrocarbons. In embodiments of the invention, the gas stream is sent through at least two pressure swing adsorption units to produce a high quality hydrogen stream, a fuel gas stream containing most of the methane and a tail gas stream that is sent to a steam cracker. Lean gas from a gas plant and other refinery off gases may also be processed together with the gas stream from the hydroprocessor.
