Description

[0002] Climate warming has attracted close attention worldwide, among which carbon dioxide is one of the most important greenhouse gases in the atmosphere. In life and production, the power industry is a key industry for carbon dioxide emissions. The flue gas exhaust containing a large amount of carbon dioxide generated by various thermal power plants in this industry is directly discharged into the atmosphere in the current process.
