Abstract:
A unit for distillation of a liquid product, said unit comprising:a vacuum column for distillation of the liquid product;means for feeding the liquid product to the vacuum column;means for removing a vapor-gas phase from the vacuum column;a vacuum-creating device including a jet device connected by its gas inlet to means for removing the vapor-gas phase, wherein the jet device is made as a liquid-gas jet device and intended for pumping the vapor-gas phase due to the energy of the liquid supplied therein, the vacuum-creating device is also provided with a pump for feeding the liquid, a separator for separation of the gas from the liquid, the pump being connected by its inlet with the separator and by its outlet with the liquid inlet of the liquid-gas jet device, the outlet of the liquid-gas jet device being connected by means of a pressure main with the separator, the longitudinal axis of the liquid-gas jet device being positioned with deviation from the vertical of plus or minus 15.degree., an outlet cross section of a liquid supply nozzle of the liquid-gas jet device is positioned above the inlet of the separator at a height from 5 m to 35 m, and an outlet section of the pressure main is positioned below the liquid level in the separator to form a hydraulic seal.
