OPERATION PROCESS OF A PUMPING-EJECTION STAND FOR DISTILLING LIQUID PRODUCTS

摘要

The present invention pertains to the technology of jet apparatus and essentially relates to a method that comprises feeding into the injector of a liquid-gas jet apparatus a liquid working medium having a vapour saturated pressure at least equal to the pressure in a vacuum rectifying column. The pressure maintained in a separator represents from 1.1 to 160 times the pressure of the vapour-gaseous phase in the rectifying column at its inlet into the liquid-gas jet apparatus. After mixing the vapour-gaseous phase with the liquid working medium, the easily condensable compounds of said vapour-gaseous phase are condensed in said liquid medium so as to obtain a gaseous-liquid mixture which is separated in the separator into a pressurised gas and a liquid medium. The method of the present invention may be used to increase the operation efficiency of a pumping and ejection stand for distilling liquid products.
