On laboratory facility studied the absorptivity of bottom liquid of methyldiethanolamine production, which is used for absorption of nitrogen dioxide from exhaust gases. Experiments were performed in the temperature range 20 – 120 °С. Concentration of nitrogen dioxides, which fed to the reactor, varied from 0,4 to 0,8 mmol/l. Surface contact between the phases changed from 0,33 to 5,73 cm2. Was proposed a new absorber for the purification of exhaust gases from nitrogen oxides. identified leakage physical absorption at a temperature below 50 °С. Indicated the presence of maximum absorbency of nitrogen dioxide at a temperature of 70 0C. Calculated the kinetic parameters of the process: the reaction rate, the reaction order equal to one, activation energy equal to 15,52 kJ/mol.
