ABSORBER AND ABSORBENT FOR REMOVING ACID GASES FROM GASEOUS HYDROCARBON-CONTAINING RAW MATERIALS Russian patent published in 2023 - IPC B01D53/18 B01D53/62 

FIELD: purification of gas materials.

SUBSTANCE: invention relates to the field of technology for purifying gaseous raw materials from carbon dioxide and can be used to purify any gaseous hydrocarbon raw materials from carbon dioxide. The absorber contains a cylindrical body, in the upper part of which there are pipes for supplying and removing the gas to be purified, and in the lower part there are pipes for supplying and removing liquid absorbent - water. A rotatable shaft is installed along the longitudinal axis of the housing, on which contact disks with holes are placed, installed with a gap relative to the housing, the shaft and each other with the possibility of partial immersion in the liquid absorbent to ensure the joint formation of the flow of the streams of the gas being purified and the liquid absorbent. Each contact disk is made with holes in which guides are located to form a directed gas flow. Seals are installed along the outer diameter of the contact disks on both sides.

EFFECT: gas purification is ensured by absorption by a physical absorbent in disk film absorbers of a developed design without regeneration of the absorbent.
