Abstract (English):
Russia is the world leader in natural gas reserves. The main deposits are located in Western Siberia, with significant reserves also found in the Volga region, the Urals, the North Caucasus region, Eastern Siberia, and the Far East. Projects to develop Arctic deposits are currently being actively pursued, although the potential of the Arctic shelf has only been partially revealed. Natural gas from the Orenburg and Astrakhan gas condensate fields has a significant hydrogen sulfide content, so it needs to be purified of sulfur compounds to reduce corrosion and environmental risks. This study is devoted to assessing the technical and economic efficiency of adsorption purification of sulfur-containing natural gases from Russian fields using new sorbents based on industrial waste and natural materials. The paper presents the developed sorption compositions, the active base of which is calcined sludge from the water treatment plant of a thermal power plant, the results of experimental studies to determine their sulfur capacity, and the cost of each proposed sorbent. To compare the developed compositions with industrial analogues, experiments were conducted on the capture of hydrogen sulfide using the ASV-22 adsorbent-absorber. To predict the required loading mass and operating time of the adsorbents, calculations were made for the purification of natural gas with its subsequent supply to a 10 MW gas turbine. The results showed that the developed adsorbents have a higher adsorption capacity compared to the industrial sample at a significantly lower cost, demonstrating the potential for using industrial waste to create economical and effective sorbents for purifying natural gas from hydrogen sulfide.
