TECHNOLOGY FOR PRODUCING COMPOSITE ABSORBENTS AND THEIR APPLICATION

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.
