At least a portion of the processed effluent mixes with the crude oil stream before the emulsion flows to the desalter.

Abstract: A system and method to vaporize a process or feed water stream does so in a liquid pool zone of a vessel as the stream comes into contact with a heating medium that is less volatile than the process stream. To keep the pool hot, the heating medium can be recirculated through a heater of a pump-around loop or a heater can be placed in the liquid pool. As the process stream is vaporized, any solids present in the process stream come out of the process stream and move into the heating medium. These solids may be further removed from the heating medium in the pool or in the pump-around loop. The vaporized process stream can be further condensed. Any heat recovered can be used to pre-heat the process stream or used in the pump around loop's heater in case of mechanical vapor recovery.
