To date, there are several methods of natural gas purification from sulfur compounds, absorption and adsorption methods are the most widespread in the industry. At the same time practical application of absorption-desorption technology of natural gas purification from these aggressive components has given positive results. As absorbents 25-30% aqueous solutions of ethanolamines (diethanolamine (DEA), methyldiethanolamine (MDEA), etc.) are used. At present 25-30% DEA and MDEA in the process of natural gas purification at gas processing enterprises of our republic: LLC "Muborak GKIZ", LLC "Shortanneftegaz", LLC "Shortan gas chemical complex", Kandym GPP, Ustyurt gas chemical complex use aqueous solutions.
