EXTRACTION COLUMN AND METHOD OF EXTRACTING COMPONENT FROM FLUID Russian patent published in 2018 - IPC B01D11/04 B01D3/14 B01D3/40 

FIELD: technological processes.

SUBSTANCE: invention relates to an extraction column. Extraction column, having, at least in sections, a cylindrical vertically directed column body, which forms the internal volume of the column, which has a horizontal maximum length, where in the column body there is at least one first supply line for an extracting agent, at least one second supply line for a fluid to be extracted, and at least one outlet line for the extractive mixture and at least one outlet line for the raffinate, characterised in that a vertically directed separating device is located in the internal volume of the column, said separating device dividing the internal volume of the column into multiple vertically directed and horizontally separated areas, wherein the horizontal maximum length of each area with each horizontal section through the column body, which separates the separating device, is less than the horizontal maximum length of the internal volume of the column, the areas at their upper edges end in the joint head of the column, and at their lower edges – in the joint bottom part of the column, where in the head section of the column and in the bottom part of the column the horizontal length of the internal volume of the column is not divided by the separating device, and one of the supply lines is located at the head of the column, and the other of the supply lines is located at the bottom of the column.

EFFECT: higher yield of the extracted component from the fluid.
