Process for the treatment of a hydrocarbon feedstock

A process for the treatment of a hydrocarbon feedstock comprising a hydrocarbon-containing liquid phase and a hydrogen-rich gaseous phase, said process comprising

• a) separating the feedstock into a liquid L1 and a gas G1, under a pressure P1,
• b) compressing at least a portion of G1 to obtain a gas stream G1* and contacting said gas stream G1* with at least a portion of L1 under a pressure P2>2×P1, so as to recover a liquid L2 and a hydrogen-rich gas G2,
• c) fractionating at least a fraction of L2 to obtain at least:
• a stabilized liquid L4a that is essentially free of LPG (liquid petroleum gases) and lighter products, a light liquid stream L4b that essentially comprises LPG, and a gas stream G4 that is at least partly recycled,
• and wherein gas G1*, optionally precooled by itself or mixed with a portion of L1 to carry out a first recovery of LPG, is subjected to counter-current contact with an unstabilized liquid AL1 comprising at least in part of L1, AL1 being cooled to below +10° C. and supercooled by at least 30° C. below its bubble point at the contact pressure.
