|Fuel Gas Sweetening (FGS) and Seawater-Flue Gas Desulfurization (SW-FGD) schemes have been proposed to be implemented at the ADGAS plant (Das Island, UAE). The implementation of such schemes is expected to reduce the SO2 emissions by 77%. The FGS scheme is expected to reduce the H2S content in the fuel gas system by 94% and results in decreasing the total SO2 emissions due to fuel gas usage by 98%. The SW-FGD scheme is expected to reduce the SO2 emissions due to incomplete sulfur recovery by 99.5%.
Globally, the SO2 emitted has the potential to travel in any direction for hundreds of kilometers depending on the meteorological conditions. SO2 is relatively stable in the atmosphere and has the ability to travel as far as 1000 km. The health and environmental impacts of SO2 can be found elsewhere. Jie constructed a model to study the impact of SO2 pollution on health over 78 Chinese counties and found that, after attaining the threshold (8 Î¼g/m2), continuous increase in industrial SO2 emission density will raise the ratio of population suffering chronicle diseases, among which respiratory diseases occupy a significant proportion.
