The natural gases known to us in the country, as well as waste process gases from production, require the removal of H2S, organic sulfur andCO2 to meet the requirements of the specifications. H2Sremoval is necessary to ensure that the gas is not toxic and for environmental reasons to reduce SO2 emissions at the point of consumption. In addition, great importance is nowadays placed on reducing corrosion due to H2Sexposure. In conclusion, sulfur is today a valuable raw material, the obtaining of which is in any case interesting.The problem of purification of hydrogen sulfide-containing technological and waste gases of production has become important due to the increasing production and processing of high-sulfur gases. Thus, the development of technical solutions to reduceSO2 emissions from sources of pollution has caused the need for comprehensive technical and environmental monitoring.The monograph is intended for scientists and specialists working in the field of chemical technology of oil and gas processing, as well as students of bachelor's and master's degrees, and doctoral students of the above specialty.
