Abstract

An apparatus and method for recovering and recycling hydrogen from a reforming process raises the pressure of at least one hydrogen-rich gas stream from at least one catalyst lock hopper and delivers at least a portion of the pressurized hydrogen-rich gas stream to at least one predetermined downstream location. At least another portion of the pressurized hydrogen-rich gas is used to maintain the desired pressure within the hydrogen recovery and recycling process and apparatus.
