DOUBLE DISTILLATION APPARATUS FOR PRODUCING TOP QUALITY ETHYL ALCOHOL DISTILLATE Russian patent published in 2023 - IPC C12P7/02 C12P7/06 B01D3/02 

FIELD: chemical industry.

SUBSTANCE: invention can be used for the production of top quality ethyl alcohol distillates. Double distillation apparatus for the distillation of ethyl alcohol, consisting of two stills, with one still inside the other, the inner still has its own temperature and vapour pressure control system, which is part of a single temperature and vapour pressure control system of the distiller, the outer still has its own vapour pressure control system connected to the first distillation cube vapour pressure control system, which is part of a single distiller temperature and vapour pressure control system, both distillation cubes are simultaneously heated by one heating element, all heating elements of which have the same power, and the temperature in the cubes is regulated by a single control system temperature and vapour pressure of the distiller, a unified system for controlling the temperature and vapour pressure of the distiller allows you to control the purity of ethyl alcohol distillate with an accuracy of 0.2%, from 60% up to 100% purity.

EFFECT: provision of an energy-efficient compact distiller with precise control of the % content of ethyl alcohol and water in the resulting distillate without harmful impurities.
