Process for treatment of a hydrocarbon feedstock that comprises a hydrocarbon-containing liquid phase and hydrogen, in which the feedstock is separated under a pressure P 1 into a liquid L 1 and a gas G 1 , that is compressed and brought into contact with a portion of L 1 under a pressure P 2 >2xP 1 to recover a liquid L 2 and a hydrogen-rich gas G 2 ; L 2 is fractionated to obtain a stabilized liquid L 4 a that is free of LPG and lighter products, a liquid stream of LPG, and a gas stream G 4 that is recycled, and in which one of gas streams: recompressed G 1 and G 4 is in counter-current contact with an unstabilized liquid AL that is obtained from or extracted from L 1 or L 2 , whereby this unstabilized liquid is supercooled by at least 10° C. below its bubble point at pressure P 2.
