Method of gas stream purification having independent vapor and liquid refrigeration using a single refrigerant

摘要

A process for recovering a hydrogen-rich gas and for increasing the recovery of liquid hydrocarbon products from a hydrocarbon conversion zone effluent by adsorption of the liquifiable products from a chilled gaseous stream with a chilled liquid stream is improved by an arrangement that uses a single refrigeration shell to provide independent temperature control of the chilled gaseous and the chilled liquid stream.
