METHOD AND DEVICE FOR CATCHING AND RECUPERATING VAPORS OF HYDROCARBONS Russian patent published in 2008 - IPC B01D53/00 

FIELD: environmental protection.

SUBSTANCE: method comprises supplying vapor-gas mixture to absorber (1) through pipeline (39). The absorber is inclined to the absorbent drain. The absorbent is supplied from pipeline (31) to absorber (1) by means of pump (34). The fraction of low-boiling vapors is absorbed when the gas-vapor mixture flows through slot spaces between disks (7) in sections (4) of absorber (1) with subsequent removing cleaned gas and absorbent from it. One part of saturated absorbent flows through pipeline (17), filter (21), heat exchanging condenser (16), collector (22), float valve (23), controlled valve (24), heater (25) and enters three-five sections of sorption unit (2), and the other unheated part enters the first section. The cleaned absorbent enters collecting vessel (8). After cooling the cleaned absorbent flows through pipeline (31), filter (33), pump (34), check valve (35), and controlled valve (36) and is returned to absorber (1).

EFFECT: reduced environment contamination.
