FIELD: process engineering.
SUBSTANCE: invention can be used in oil-and-gas industry, oil processing, chemical and petrochemical industries for absorption cleaning of process gases from acid components with application of aqueous solutions of alkanolamines. Proposed device comprises separator, device to mix gas with absorbent, two-section absorber with mist extraction device, top packed mass exchange section equipped with distributing device, bottom section equipped with the set of radial-helical heat exchangers with distributing devices and coolant or heat carrier feed and discharge pipes, absorbent feed pump, device to clean circulating amine solution from decomposition products, gas feed and discharge pipes and process pipelines. Note here that absorber bottom is located above the point saturated absorbent is fed into stripper with allowance for pressure difference in absorber and stripper.
EFFECT: reduced loss of absorbent and amount of desalinised water.
