Abstract
High purity hydrogen is produced at high recovery from liquid anhydrous ammonia. Ammonia is vaporized and subsequently dissociated into is constituents. The resulting dissociated gas stream is passed to an adiabatic metal hydride purification unit to absorb hydrogen present in the stream. The adsorbed hydrogen is then recovered as high purity product.
