ABSTRACT:
Process for the treatment of a hydrocarbon mixture that comprises hydrogen, in which the mixture is separated at pressure P1into a liquid L1and a gas G1that is compressed under a pressure P2>2×P1; compressed gas G1** is then brought into contact with at least a portion of L1so as to recover a liquid L2and a hydrogen-rich gas G2; at least one stabilized liquid and a light liquid stream LL comprising primarily LPG, of which at least a portion is reduced in pressure and mixed with gas G1to facilitate its compression, are recovered by fractionation from G1** and/or from L2. The invention also relates to a process for reforming hydrocarbons with such an effluent treatment.
