ABSTRACT:
A pressure swing adsorption process, which involves storing part of the residue gas obtained from the desorption of an adsorption zone in a residue gas vessel and venting part of the residue gas or withdrawing part of the residue gas with a compressor to enable a further decrease of the pressure in the adsorption zone in question, provides an improved efficiency as to the recovery of the product gas and allows for further use of the stored residue gas. The process is particularly suitable for employment in the production of hydrogen from the steam reforming of hydrocarbonaceous feedstocks and the subsequent purification of the crude hydrogen thus produced by the improved pressure swing adsorption process.
