Assessment of the emission of air pollutants and greenhouse gases in the flue gas from coal-fired power plants in Vietnam

Tóm tắt

Coal-fired power plants (CFPPs) are an important energy source and the major source of air pollutants as well as greenhouse gases (GHGs) in Vietnam. The emission data of air pollutants and GHGs are an important base for setting up control strategies and management policies. This study assesses the emissions of PM_2.5, PM₁₀, SO₂, NOx, CO, CH₄, N₂O, and CO₂ from CFPPs in Vietnam in 2019, and 2021 and predicts those in 2030 based on coal consumption and emission factors. A method to estimate PM_2.5 and PM₁₀ emission based on the emission of PM and size distribution was proposed to overcome the difficulty of lacking data and measuring those parameters in the flue gas in Vietnam.
