Operation process of a pumping-ejection stand for distilling liquid products

摘要

Essence of the invention is a: a liquid, whose saturated vapour pressure is not less than the pressure at the top of a rectification column, is delivered into the nozzle of a liquid-gas jet apparatus as a motive liquid; the pressure maintained in a separator represents from 1.1 to 160 times the pressure of a vapor phase at the inlet of the liquid-gas jet apparatus; condensation of easy-condensable components of the vapor phase in the motive liquid and forming of a liquid-vapor mixture take place after mixing of the vapor phase with the motive liquid; the liquid-vapor mixture is separated in the separator into a compressed gaseous component and a liquid medium.The introduced method results in an increase in efficiency of a pumping-ejector system for the distillation of a liquid product.
