Elemental mercury in flue gases from coal combustion is difficult to control. However, oxidized mercury species are soluble in water and can be removed with a high degree of efficiency in wet flue gas desulphurization (WFGD) systems operating in coal combustion plants, provided that no re-emissions occur. In this article the mechanisms affecting the re-emission of oxidized mercury species in WF...

A concise one dimensional thermal-hydraulic two-fluid model is presented for the numerical prediction of sulphur dioxide absorption from the flue gas onto drops of the water-limestone slurry in the vertical spray tower absorber. The model is based on mass, momentum and energy balance equations for each phase separately, i.e. downward falling droplets of water-limestone slurry and upward flowing...

This paper presents the integrating Life Cycle Assessment (LCA) and Life Cycle Costing (LCC) study of the Flue Gas Desulphurization (FGD) system in Fengcheng thermal power plant in China. The FGD systems have been installed in a power generation plant to reduce the large amount of SO2 emission. Studies to appraise FGD system in power plant have mainly focused on economic analysis. This paper gi...
