PLANT AND METHOD FOR TREATMENT OF HYDROCARBON FLUID Russian patent published in 2006 - IPC C10G31/00 C10G33/00 B01D19/00 

FIELD: treatment of hydrocarbon fluids (oil, petroleum, bitumen); cleaning, dehumidification and degassing of these fluids by separation of phases.

SUBSTANCE: proposed plant has two loops interconnected by means of vapor-and-gas pipe line equipped with shut-off and adjusting fittings. Each loop contains supersonic liquid-and-gas ejector which is mounted with intake chamber upward. Intake chamber of ejector of first loop is equipped with tube for delivery of medium to be treated; it is mounted coaxially relative to chamber. Intake chamber of ejector of second loop intended for evacuation of first one is equipped with tube for delivery of working fluid which is coaxial relative to chamber. Vapor-and-gas pipe line is used for connecting the intake chambers of first and second loops. One loop is provided with circulating main and tank for circulating fluid with heat exchanger in its lower part. Preheated hydrocarbon fluid is fed under pressure to nozzle unit of first loop ejector forming supersonic two-phase mixture of fluid and gases and vapors liberated from it in ejector mixing chamber.

EFFECT: enhanced efficiency at high degree of degassing and/or dehumidification of hydrocarbon fluids.
