MAQOLA ANNOTATSIYASI

The article discusses the main prospects for the technology of purifying natural gas from acidic components and the problems of ensuring the purity of oil and gas products in accordance with state standards. An increase in the degree of purification from H2S, CO2, elemental sulfur, carbonyl sulfide, ethyl mercaptans (thiols), methyl mercaptan, carbon disulfide, sulfides, disulfides (dithioethers), thiophene, sulfoxides and sulfones is considered. Also, the physicochemical properties of the absorbent for the purification of sulfur compounds (generated during natural gas processing) are studied. Based on the study of various absorbents (ethanolamine (EA), methylethanolamine (MEA), diethanolamine (DEA), methyldiethanolamine (MDEA), DGA-diglycolamine and combined absorbents), the following were identified: high sorption capacity, selective separation of no more than 20 mg/m3, corrosive resistance to metals, low foaming, and they are often used in the production: MDEA and DEA absorbents. Thus, the processing of high-sulfur natural gases containing sulfur is an urgent and targeted task for the gas industry of the Republic of Uzbekistan, which has scientific and practical meaning (for this, research must be carefully scrutinized). This concerns the development of new absorbents, the introduction of a combined method of gas purification and increasing the efficiency of technologies for purifying natural and secondary gases from sulfur compounds
