ABSTRACT:
By incorporating a gas permeable membrane into a hydrogen purification process at the front end of the cryogenic unit, the low purity hydrogen can be made into a high purity stream and a low purity stream. The critical pressure of the low purity stream is such that the low purity stream can be purified cryogenically without depressurization.
