Study and practice of sodium carbonate production from flue gas and caustic soda
Combined with traditional soda ash production processes,and by analyzing the detection data of emitted flue gas,the feasibility and economy of a process of preparing sodium carbonate from flue gas and caustic soda are demonstrated and analyzed.A technical plan and process package are formed.A 40-kt/a sodium carbonate production plant are built.This plant prepares sodium carbonate solution through the absorption reaction of self-produced caustic soda and flue gas discharged from boilers,achieving self production and self use of carbonate.The plant continuously,automatically and stably operates,reduces carbon dioxide emissions by 160 kt/a,saves production costs of 5 million yuan/a,achieving significant environmental and economic benefits.
