Abstract:
The present invention relates to a method of improving the efficiency of an integrated hydrogen generation system by the introduction of a means to heat the PSA tail gas within the PSA surge tank.

Claim (Index 1):
A method of improving the efficiency of an integrated hydrogen generation system comprising:\n producing a syngas stream in a steam reformer which has a combustion zone; introducing at least a portion of the syngas stream to a water gas shift reactor; cooling the shifted syngas stream to produce a cooled shifted syngas stream; introducing the cooled shifted syngas stream into a pressure swing adsorption unit, thereby producing a stream of predominantly hydrogen and a tail gas comprising predominantly byproducts; routing said tail gas to one or more surge tank(s) having a heat exchange device disposed therein and indirectly heating said tail gas by passing it over a surface of said heat exchange device inside which a hot fluid is cooled, thereby obtaining a heated tail gas; and routing said heated tail gas to the combustion zone of a reformer.
