ABSTRACT:
Unreacted hydrogen contained in the gaseous effluent from a high pressure hydrogenation process is reduced in pressure, followed by purification of the hydrogen at the lower pressure, and recompression to a high pressure for use in a hydrogenation process. Liquid effluent is also reduced in pressure, hydrogen stripped therefrom, and combined with the recovered hydrogen gas at the lower pressure for purification.
