Abstract: The present group of inventions relates to processing of multi-component liquid mixtures (MCLM) employing reforming process, preferably for vacuum distillation of hydrocarbon mixtures and can be applied in petroleum refining and chemical industries. The group of invention comprises the method for processing of multi-component liquid mixtures and the plant for its implementation The claimed method of MCLM separation comprises pressurized feeding of hydrocarbon liquid mixture to an ejector nozzle with its further discharging to a vacuum chamber. The novel feature of the method is creation of additional counterpressure jointly with the ejector providing for concentration of power in the vacuum chamber to form a pressure surge. The claimed plant for MCLM processing comprises a feeding pump, a head delivery main, a discharge main, control instrumentation and an evacuating device comprising a horizontal vacuum chamber.
