FIELD: chemistry.
SUBSTANCE: invention relates to use of a reagent based on sulphided iron to remove oxygen from streams of gaseous and liquid fluid media such as natural gas, streams of light hydrocarbons, crude oil, mixtures of acidic gases, streams of gaseous and liquid carbon dioxide, anaerobic gas, landfill gas, geothermal gases and liquids. The invention relates to a method of removing oxygen from gaseous and liquid fluid media which contain one or more sulphur-containing compounds. The method involves providing a reagent primarily containing a divalent iron compound; preliminary sulphidation of said reagent by bringing into contact with a sulphur-containing compound; bringing a sulphided absorbent into contact with fluid medium.
EFFECT: continuous removal of oxygen from a stream of gaseous and liquid hydrocarbons.
