Abstract
NO is difficult to be rapidly oxidized and absorbed in the wet oxidation method used in the treatment of the NO x exhaust gases produced in the production process of propellants and explosives, which cause the low absorption rate. To solve this problem, ferrous complex FeII(EDTA)2- (Ethylene Diamine Tetraacetic Acid, EDTA)was used as the absorbent of NO in a bubbling reactor. The effects of absorbing solution concentration and NO gas concentration on the absorption rate were investigated. The mass transfer-reaction process of NO absorption was analyzed. The theoretical model describing the NO absorption process was derived. Results show that: under experimental conditions, the absorption rate increases linearly with the increase of NO concentration, and the NO absorbed by FeII(EDTA)2- is a pseudo first-order reaction process. The error between calculated values obtained by absorption process model and experimental ones is within 5%, both have good consistency, which can be used to describe the mass transfer-reaction process of NO absorbed by FeII(EDTA)2- solution.
