Abstract
A membrane unit is able to recover hydrogen from a resid waste gas stream. Two membrane units provide even greater hydrogen recovery. The membrane separation is performed at conditions that allow the pressure of the recovered hydrogen to enter into a second stage of compression, saving the expense of the first stage of compression.
