Kobzyev O. Homogenous-heterogeneous oxidation of NO in nitric acid production

The reaction of NO oxidation, including in the process of nitric acid production. Aim of the investigation. The determination of the factors which influence on the process of NO oxidation under homogenous conditions with next determination of the influence of the extended surface of phase boundary "gas-solid" on the degree of NO oxidation. Experimental investigations of NO oxidation process on the pilot plant. The evaluation of the influence of hydrodynamic conditions on NO oxidation with oxygen is given. Qualitative and quantitative characteristics of pack influence on the process of NO oxidation are made. The technique of regulation of correlation between oxidation process and absorption process is suggested. The technological scheme of nitric acid production is proposed. Degree of inculcation. The technology is put into practice under industrial conditions. Main chemistry plants, nitric acid production and installations of industrial wastes cleaning from nitrogen oxides.
