Treatment of exhaust gases with methyldiethanolamine solution to remove sulfur dioxide

The possibility of absorbing sulfur dioxide from exhaust gases of thermal p ower stations and industrial installations with the use of liquid amine-con taining absorbents - vat residues of methyldiethanolamine production, was s tudied in a wide range of process parameters. Particular attention was give n to the influence of high temperature and low sulfur dioxide concentration , corresponding to real parameters of industrial waste gases, on the absorp tion rate and absorption capacity.
