Abstract: In the Laboratory of Environmental Catalysis of the Boreskov Institute of Catalysis, new processes based on direct catalytic oxidation of hydrogen sulfide were developed. The technology was successfully tested in pilot scale on the largest sour gas fields, refineries and gas processing plants in Russia. In 2011 full scale industrial installation was set into continuous operation at the Bavly oil-field (OJSC “Tatneft” – company-operator). The efficiency of hydrogen sulfide removal was proved to exceed 99%. During two years of continuous operation:  120 106 m3 of commercial gas were produced;  1200 tons of hydrogen sulfide were recovered as elemental sulfur;  emission of more than 2300 tons of sulfur dioxide and sulfuric acid to the atmosphere was prevented;  pollution damage for the amount of $ 10 million was averted. Characteristics of the produced sulfur surpass those specified by Russian National Standard #127.1-93 (commercial grade sulfur 9990).
