Abstract
A method for extracting carbon dioxide from a flue gas includes a preparing process, an acid removing process, and a purifying and liquefying process. The preparing process is implemented by collecting the flue gas generated by oxygen-enriched combustion of a glass raw material with methane from a glass furnace. The flue gas includes the carbon dioxide, nitrogen, water vapor, oxygen, fluoric acid compounds, and boric acid compounds. The acid removing process is implemented by performing a first acid removing operation. The first acid removing operation is implemented by using a sodium hydroxide aqueous solution to remove the fluoric acid compounds and the boric acid compounds in the flue gas. The purifying and liquefying process is implemented by using a purifying and liquefying unit to extract the flue gas that already undergoes the acid removing process, so as to obtain liquid carbon dioxide having a purity greater than 99%.
