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.
A process for producing hydrogen having a purity of at least 99.9% at a recovery of at least 95% from liquid anhydrous ammonia, said process comprising: (a) vaporizing said liquid anhydrous ammonia to produce a gaseous ammonia stream; (b) passing said gaseous ammonia stream to a dissociation unit to dissociate the gas stream to its constituents; (c) compressing said dissociated gas stream to a pressure between 150 and 250 psia; (d) passing said compressed dissociated gas stream to an adiabatic metal hydride purification unit to adsorb hydrogen present in...
