Abstract
Pertaining mainly to the field of the petrochemical industry the method essentially includes delivery of a motive liquid into a liquid-gas ejector from a separator by a pump, feeding a liquid-gas mixture obtained in the ejector into the separator, cooling of the motive liquid with simultaneous heating of a circulating portion of a distillation residual while the motive liquid is pumped through a heat-exchanger/heater by the pump, and maintaining such an operational mode while the temperature of mediums in the separator is higher than the temperature of the motive liquid at the nozzle inlet of the ejector, where the latter is higher than the temperature of the distillation residual at the point of discharge from a rectification column and the temperature of a gas-vapor phase at the gas inlet of the ejector is lower than the temperature of the distillation residual at the point of discharge from the column. The invention also relates to a system for realizing this method, which has a rectification column, a liquid-gas ejector, a pump, a heat exchanger and further is furnished with a separator. An outlet of the ejector and the suction side of the pump are connected to the separator, a…
