Abstract: 1. Method of treating of liquid mixtures by means of vacuum distillation comprising the supply under pressure, of hydrocarbon liquid mixture into the nozzle of liquid-gas-jet device with the following outflow if it into the vacuum-camera, characterized in that base liquid mixture is supplied to the nozzle of jet device under the pressure of 1 - 12 Mpa, and diphasic supersonic flow is formed in vacuum-camera due to the boiling up of a part of liquid mixture, after that counter-pressure is formed, providing a forming in vacuum-camera of jet device of pressure jump with avalanche-like condensation of gaseous constituent of diphasic flow. 2. Method of treating of multi-component liquid mixtures by means of vacuum distillation, mainly of spirit-aqueous solution or mash. Comprising the supply under pressure of base liquid mixture in hermetic capacity, containing inert gas, with the following ejecting by its base mixture in vacuum-camera of liquid gas-jet device, then separation by means of inert gas of gas-vapor low-boiling component of mixture from not-reacted mixture components, transporting of formed gas-vapor low-boiling component of mixture through defoamer in condenser and then - of condensed ready product- in storage capacity, characterized in that in counter-pressure is further formed in vacuum-camera, which provides the forming of pressure jump, then the formed vapor-gaseous low-boiling component of mixture is separated from not-reacted mixture components and subjected to condensation by famous method, and not-reacted components of mixture are rendered back in vacuum-camera through the drain pipe by closed loop for repeated cycle separation. 3. Plant for treating of multi-component liquid mixtures by means of vacuum distillation, comprising feed pump, drain and delivery pumps, controlling instruments and vacuum-making device, comprising horizontal vacuum-camera, characterized in that the vacuum-making device is made as connected to delivery pipe liquid-gas-jet device, the nozzle being mounted in front end wall of vacuum-camera, the length related to diameter of cavity being: L=(7-10)*D, wherein: L - length of vacuum-camera, D - diameter of vacuum-camera cavity, and unit further comprises a counter-pressure regulator, made with the possibility of providing together with liquid gas-jet device of conditions of forming of pressure jump in vacuum-camera and connected by means of pipeline to back end wall vacuum-camera, and vacuum pressure gage, communicated with vacuum-camera cavity in front part. 4. Unit according to claim 3, characterized in that the flowmeter, thermometer and manometer are further connected to delivery pipe between feed pump and jet device. 5. Unit according to claim 4, characterized in that it further comprises successively connected between each other defoamer, cooled condenser and a storage capacity, which by means of pipeline with connected compressor is communicated with delivery pipe of vacuum-camera, communicated with defoamer and forms with the last ones a closed loop, drain pipe being by means of pipeline of rendering of not-reacted gas-liquid mixture is communicated with capacity for base liquid, which with help of pipeline of supply of base liquid is communicated with feed pump and forms a second closed loop with vacuum-camera.
