The main purpose of the study is to study and analyze the causes of degradation of 25-30% solutions of ethanolamines (methyldiethanolamine and methylmethyldiethanolamine) used in natural gas purification. The negative changes in ethanolamines that affect their physicochemical properties, absorption capacity and efficiency of gas cleaning as a result of destruction were studied. It has been established that one of the main factors affecting the working properties of ethanolamines and their regeneration is their saturation with high-temperature-resistant salts, organic acids, bitsins, di-, tri-, tetra-amine compounds. As a result of research and analysis, the possibility of increasing the efficiency of gas cleaning by reducing the volume of ethanolamines purchased from abroad and extending the service life as a result of the reuse of ethanolamines from the above substances in the gas cleaning process was studied. As a result, the negative impact on the environment, flora, soil structure, and ground and surface waters has been reduced by reducing their release into the environment.
