Process for the recovery of a gas rich in 1996 and a liquid stabilized

摘要

Process for the treatment of a hydrocarbon mixture comprising hydrogen, in which it is separated out at a pressure p1, the mixture in a liquid l1 and a gas g1, which is compressed under a pressure p2 2 x p1, it is then placed in contact with the compressed gas g1 * * with at least a portion of l1, so as to recover a liquid l2 and a gas, g2, which is rich in hydrogen, is recovered by fractionation from g1 * * and / or from l2, at least one liquid and a stabilized current light liquid l 1 of the lpg, at least a portion is expanded and mixed with the gas g1 to facilitate its compression.l' invention also relates to a process for the reforming of hydrocarbons with such a treatment of effluents.
