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 in petroleum refining and chemical industries. The inventions include the method for processing of multi-component liquid mixtures. The method of MCLM separation includes pressure feeding of a hydrocarbon liquid mixture to an a liquid-gas jet device nozzle which discharges to a vacuum chamber of liquid-gas jet device. A counter pressure jointly with the liquid-gas jet device forms a pressure surge in the vacuum chamber. The counter pressure is 0.4 to 0.7 of the magnitude of the feed pressure generated by the pump. The plant for MCLM processing includes a feed pump, a head delivery main, a discharge main, control instrumentation and a vacuum-generating device including a vacuum chamber, a liquid-gas jet device with a nozzle in the front end wall of the vacuum chamber. The length of the nozzle exceeds its diameter by a factor 7 to 10. The plant includes a counter pressure regulator connected through a conduit to the rear end wall of the vacuum chamber.
A plant for multi-component liquid mixtures processing comprising a feeding pump (2), a head delivery main (3), a discharge main (4), control instrumentation (11, 12, 13, 14, 19) and a vacuum-generating device (5) comprising a horizontal vacuum (1), wherein the vacuum-generating device (5) is implemented as a liquid-gas jet device (1, 5, 6, 7, 10) connected to the head main (3), a nozzle (6) of which is integrated into a front end wall (7) of the vacuum chamber (1), having a length with respect to its cavity diameter meeting the equation
A method for processing of multi-component liquid mixtures by vacuum distillation comprising pressure feeding a feed hydrocarbon liquid mixture to a nozzle of a liquid-gas jet device which comprises said nozzle and a vacuum chamber, said nozzle discharge into said vacuum chamber, said feed hydrocarbon liquid mixture is pumped to said nozzle at a feed pressure or 1 to 12 Mpa which is generated by pump, wherein due to vaporization of a part of said feed liquid mixture a two-phase supersonic flow is formed in said vacuum chamber, and then a counter presser is generated which causes a pressure surge in said vacuum chamber with avalanche condensation therein of a gaseous component of said two-phase flow, said counter pressure is 0.4 to 0.7 of the magnitude of said pressure generated by said pump.
