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
