A process for the dehydration and/or desalination and simultaneous fractionation of a petroleum deposit effluent containing oil, associated gas and water which can be saline, which process comprises: (a) at least one step for separating the liquid and gaseous phases at the pressure P1 for removal of the gas, producing a gaseous fraction G1, on the one hand, which is removed and a liquid fraction L1, on the other hand, which is sent to step (b) at least one step for separating, at least partly, the two liquid phases mixed in the liquid fraction L1, the aqueous phase being partly removed and the oil phase containing a quantity of residual aqueous phase being sent to step (c); (c) at least one distillation step carried out at a pressure P2 which is less than, or at the most equal to, the pressure P1 in step (a), in a distillation zone C1, said distillation being carried out in the presence of the oil phase coming from step (b), said zone C1 comprising an internal heat exchange zone and a boiling zone, and enabling a gaseous fraction G2, on the one hand, and a liquid fraction L2, on the other hand, to be recovered, said fraction L2 being constituted by a liquid oil phase and an aqueous liquid phase which is not miscible with the liquid oil phase; and (d) at least one step for separating the two liquid phases mixed in the liquid fraction L2, the oil phase being sent into said internal exchange zone, and then removed.

A process for dehydration and/or desalination and simultaneous fractionation of a petroleum deposit effluent containing oil, associated gas and water, which is optionally saline, which process comprises: (a) separating the petroleum deposit effluent containing oil, associated gas and water at a pressure P1 to produce a gaseous fraction G1 and a liquid fraction L1 comprising an oil phase and an aqueous phase, and removing the gaseous fraction, (b) partly separating the liquid fraction L1 to produce a separated aqueous phase, which is removed, and an oil phase containing a residual quantity of aqueous phase, (c) distilling, in at least one distillation step, at a pressure P2 which is less than or equal to the pressure P1 in step (a), said oil phase comprising a residual quantity of aqueous phase produced in step (b) in a distillation zone (C1) comprising an internal heat exchange zone, having a plurality of vertical tubes surrounded by a calandria, and a boiling zone, wherein said oil phase comprising a residual quantity of aqueous phase flows as a falling film inside the vertical tubes, to produce a gaseous fraction G2 and a liquid fraction L2 which comprises a liquid oil phase and a liquid aqueous phase immiscible with the liquid oil phase, (d) separating said liquid fraction L2 to produce a separated oil phase and separated aqueous phase, and (e) passing the separated oil phase through the calandria outside of and in an indirect heat exchange relationship with the vertical tubes in the internal heat exchange zone.
