Reduction of waste disposed to the environment through recycling of unused methyldiethanolamine

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