ABSTRACT

During combustion of natural fuels together with oxides of main fuel elements (carbon and hydrogen) fly ash with unburnt fuel particles, sulfur oxides, nitrogen oxides, some amount of fluorine-containing compounds and gaseous products of incomplete combustion of fuel are released into the atmosphere. The technology and technological parameters of equipment for purification of exhaust gases of TPP, which allows to remove up to 95% of sulfur and carbon oxides by low-temperature liquid-phase catalytic oxidation at atmospheric pressure and conversion of exhaust gases of TPP into full secondary products (carbon dioxide and sulfuric acid) is presented. Stoichiometric equations of reprocessing of exhaust gas of TPP into secondary chemical products are presented. The use of effective metal-polymeric catalyzer for purification of exhaust gases of TPP, which allows to recycle sulfur dioxide simultaneously with its oxidation into sulfuric acid is shown. Perspectives of obtained results consist in development of new approaches in the field of ecology and chemical technology of recycling of exhaust gases of TPP into full secondary products (carbon dioxide and sulfuric acid), which are in demand in the market of chemical products.
