Abstract
A process is disclosed for the recovery of hydrogen and C.sub.6 -plus product hydrocarbons from the effluent stream of a hydrogen-producing hydrocarbon conversion process. The effluent stream of the reaction zone is partially condensed to remove the bulk of the heavy C.sub.6 -plus hydrocarbons, which are then sent to a fractionation zone. The remaining vapor is compressed to a substantially higher pressure. The compressed vapor is then passed into a membrane separation zone in which a hydrogen-rich stream is separated from the compressed vapor. The relatively high pressure nonpermeate portion of the vapor stream which emerges from the membrane separation zone is partially condensed by autorefrigeration. The still high pressure mixed phase fluid is separated into vapor and liquid portions. The liquid phase material is then flashed to produce coolant used to perform the partial condensation.
