FIELD: technological processes.
SUBSTANCE: invention is related to the field of chemistry and may be used for cleaning of hydrocarbon and smoke gases from acid components, namely, from sulfury gases, carbonic acid gas and mercaptans. Stripping solution contains previously crushed and hydrated metallurgical scale, lime, hydroxide of alkaline metal and organic additives - polyacrylamide (PAA) or CMC, at the following ratio of components, wt %: scale 1-8, lime 1-8, alkaline metal hydroxide 1-10, PAA or CMC 0.1-0.5, water - the rest.
EFFECT: makes it possible to increase extent of gas cleaning from acid components, to solve ecological problems by recycling of metallurgical industries wastes - scale, and also to use hard sludge produced as a result of gas cleaning as construction material.
