RECTIFICATION METHOD Russian patent published in 2019 - IPC B01D3/26 

FIELD: technological processes.

SUBSTANCE: invention relates to methods for carrying out heat and mass transfer processes, in particular to the process of cyclic distillation. This method of distillation, containing the flow of the original mixture, reflux and steam in a distillation column in which they are separately moved using contact mass transfer plates, and in the period of the flow of the liquid phase the flow of the vapor phase is cut off, and the output of the finished product, characterized in that the supply of the initial mixture and steam is carried out continuously, in addition, the space of the distillation column is divided into independent sections, the column contains distribution devices, made with the possibility of simultaneous supply of the initial mixture and reflux successively in each of the sections, in addition, the flow of the vapor phase is cut off for the section into which the liquid phase enters.

EFFECT: technical result is expressed in increasing the efficiency and optimization of the rectification process in a cyclic mode.
