FIELD: chemistry.
SUBSTANCE: invention relates to a method and a multicomponent cleaning composition for removing sulphur-containing compounds, such as H2S and mercaptans from gaseous sulphur-containing stream, as well as to treated gaseous hydrocarbon flow containing multicomponent cleaning composition. Method includes: contacting a gaseous sulphur-containing stream with a multicomponent cleaning composition for removing a sulphur-containing compound which contains at least one purifier for removing the sulphur-containing compound; and at least one hygroscopic reagent. Additionally, the gaseous sulphur-containing stream contains a quantity of water which is less than or corresponding to relative humidity of 100 %, and the said gaseous sulphur-containing stream contains a sulphur-containing compound.
EFFECT: technical result consists in removal of sulphur-containing compounds from flows of dry gas or streams of non-dried gas, as well as in preventing corrosion.
