METHOD OF SEPARATING MIXTURES WITH HIGH CONTENT OF LIQUID-PHASE PRODUCT Russian patent published in 2017 - IPC B01D3/14 B01D3/22 B01D19/00 C10G7/00 C10G7/02 C10G31/00 C07C7/04 

FIELD: technological processes.

SUBSTANCE: method of separating mixtures with high content of liquid-phase product using a tray column with horizontally mounted curtains and vertically positioned tray drain devices comprises injecting the raw material to the column by one or two streams, forming the raw material of two fluid streams in the column below the water level, forming upwardly flowing vapour (gas) stream at the bottom of the column by injecting a stripping agent and (or) by heating and evaporating of part of the fluid streams, alternating contact of the fluid streams with the upwardly flowing vapour (gas) stream of the column at the curtains of only their group of trays, transporting of fluid streams to the column bottom by avoiding the tray groups of another fluid stream, withdrawal of separation products from the column in liquid and vapour (gas) phases, wherein the alternating contact of the fluid streams with the upwardly flowing vapour (gas) stream is carried out at the curtains of adjacent column trays to produce liquid-vapour (gas) system with high monodispersity degree and highly-developed surface of phase connecting using the curtains with finely perforatedirreversible elements, transporting of fluid streams to the column bottom is carried out only by tray drain devices.

EFFECT: increased fluid-carrying capacity and separating capacity of column lower than the level of raw material input.
