Universal Installation for the integrated utilization of flue gases and wastewater from thermal power plants

Abstract

For 30 years research has been carried out on the use of wastewater from thermal power plants and industrial boilers, as well as on the use and extraction of various components from flue gases such as carbon dioxide, sulfur and nitrogen. Technological solutions were developed and implemented in various productions at various times: use of acid-forming components of flue gases for the regeneration of cation exchangers; carbon dioxide from flue gases of 99.9% purity with “food” quality; technical nitrogen of 95-99 purity from flue gases; wastewater usage to increase the degree of sulfur oxides from flue gases. The article presents a technological solution for the integrated utilization of flue gases and wastewater from a thermal power plant with high-pressure boilers burning solid fuels.
