METHOD OF SEPARATION OF THE ALCOHOL-WATER MIXTURE AND THE INSTALLATION FOR ITS REALIZATION Russian patent published in 2006 - IPC B01D3/00 B01D3/14 C12G3/10 

FIELD: processes liquid mediums separation processes; methods and devices for alcohol-water mixtures separation.

SUBSTANCE: the invention is pertaining to the separation processes of liquid mediums. According to the method the alcohol-water mixture is fed into the ejector under pressure, ensuring a continuous flow of the hypersonic two-phase mixture consisting of the liquid phase and the vapors evaporated from it. These vapors are removed from the inlet chamber of the ejector by its vacuumization with the help of the second hypersonic ejector, which has been included in the second loop of circulation of the working medium. The alcohol-water mixture is fed into the ejector at the temperature exceeding the temperature of the circulating medium in the independent loop by the value, which ensures at least twofold exceeding the pressure of boiling of the separated alcohol-water mixture over the pressure of boiling of the circulating working medium. The installation contains: two loops, each of which is supplied with the hypersonic ejector mounted vertically with its inlet chamber upward; the steam-gas pipe duct directly bridging the inlet chambers of ejectors of the first and the second loops. The first loop contains the pipe ducts for the feeding of the being separated medium and for withdrawal of the alcohol depleted component. The second loop contains: the withdrawing alcohol enriched component pipe duct; the circulating main with the pump and the tank for the circulating medium, in the lower part of which there is the heat exchange device. The invention allows to increase the degree of separation of the mixture at using the small-size installation.

EFFECT: the invention ensures the increased degree of separation of the mixture at using the small-size installation.
