RECTIFICATION COLUMN Russian patent published in 2023 - IPC B01D3/16 

FIELD: hydrocarbon processing.

SUBSTANCE: invention relates to mass transfer equipment in the field of hydrocarbon processing. The invention is a rectification column, which contains housing with bases, pipes for input of feed and output of products, bubble caps alternating in height with central and lateral overflows located inside the housing. Spiral baffles having a rectangular shape in cross section are placed on the upper surfaces of the bubble caps. Caps, the distance between which decreases from the centers of the bubble caps to the periphery, are installed at the same distance from the turns of the spiral baffles. The lateral overflows of the bubble caps are placed in their peripheral parts between the turns of the spiral baffles. The central overflows of the bubble caps are installed perpendicular to their planes, in the centers of the spiral baffles.

EFFECT: reducing the number of caps, reducing its height and simplifying the design.
