Background. The produced water of the gas fields contains hydrogen sulfide, which is corrosive to metal equipment in the fields. Technological methods have been developed for neutralizing and extracting it from these waters. They have been successfully tested under production conditions, and a method of electrochemical neutralization of hydrogen sulfide is being implemented. Purpose to develop a technology for reagent-electrochemical treatment of acidic formation water of gas fields. Methodology. The reservoir water of the Urtabulok-Samontepa field of Mubarekneftegaz LLC was selected as the object. The concentration of hydrogen sulfide was controlled, electrochemical measurements were performed on a PI-50-1 potentiostat. A pilot installation of the electrolyzer and sump was made. Originality. The rules for the process of reagent-electrochemical treatment of acid formation water of gas fields, leading to the purification of water from hydrogen sulfide, have been developed. Findings. The kinetic laws of neutralization and oxidation of hydrogen sulfide in solution are revealed. The anode material was chosen - carbon steel, the dissolution of which generates iron ions (II, III). The technology of water purification from hydrogen sulfide has been developed. The calculation of the productivity of the electrolysis pilot plant at the Mubarek gas processing plant was performed. It is being installed. Highlights: * a technology for the treatment of produced water from H2S has been developed; * the anode material of the pilot plant for its neutralization was selected.
