A 30% aqueous solution of waste methyldiethanolamine (MDEA) can be regenerated, reused in gas treatment, and its residue can be used as a secondary raw material in another area of production. (HOCH 2 CH 2 ) 2 NСH 3 is separated from water by a 30% aqueous vacuum-extraction method. MDEA and its destroyed part remain in the column. In laboratory conditions, it was shown that the degree of purification from destruction products by this method is from 60 to 78%. The analysis of the research results showed that the parameters of the main operational properties (density, viscosity, surface tension, foaming) of purified amine were significantly improved.
