Abstract: A device comprising at least one absorber, at least one cold separator from which is extracted a gaseous phase that feeds the absorber, at least one recycling to said cold separator of at least a portion of liquid effluent that is obtained from the absorber and which is mixed with the feedstock, at least one heat exchanger for cooling the mixture prior to the recycling, at least one conduit for recovering a light hydrocarbon-enriched liquid fraction obtained from the cold separator and at least one conduit for evacuating gases from the absorber, said device being useable for the treatment of a hydrogen-rich gas or for the recovery of a hydrocarbon-enriched liquid.

Abstract: The invention relates to a device that comprises at least one absorber, at least one cold separator from which is extracted a gaseous phase that feeds the absorber, at least one recycling to said cold separator of at least a portion of the liquid effluent that is obtained from the absorber and is mixed with the feedstock, at least one means for cooling said recycling, at least one means for recovering a light hydrocarbon-enriched liquid fraction that is obtained from said cold separator and at least one means for evacuating gases from the absorber. The invention also relates to a process for a hydrogen-rich gas or a process for recovery of a hydrocarbon-enriched liquid that uses said device.

Abstract: Apparatus for conducting an improved method of processing a catalytic reformate with an improved production of hydrogen. The apparatus comprises units for conducting a separation stage, absorption at 20.degree. to 60.degree. C. and at a pressure of at least 10 bars, purification of hydrogen over adsorbent beds and recycling of the residual gas obtained at purification.
