CO2 Emission on the Process of Desulphurization Projects during "11th Five-Year Plan" Period

China established a national level of principle pollutions (SO₂ and COD) emission that 10 percent reduction of SO₂ and COD emission by priority projects, structural adjustment, and environmental management during the "11^th Five-Year plan" period. This paper focused on the induced effect to CO₂ emission on the process of desulphurization projects. CO₂ emission related to three parts of desulphurization process: desulphurization facilities construction, desulphurization facilities operation and replacement reaction on the process of desulphurization operation. Energy consumption play an important role when calculate CO₂ emission on the process of desulphurization facilities construction and operation, and balance of materials is the major method to calculate CO₂ emission on the process of replacement reaction in desulphurization. It came up with that 3.43 tons CO₂ discharge when reduce 1ton SO₂ on average during the "11^th Five-Year plan" period.
