摘要

The flue gas emitted by burning of fossil fuels is a significant source of the atmospheric sulfur dioxide (SO2). As SO2 can produce eventually sulfuric acid after oxidation and reaction with water, it is considered as one of the main sources causing acid rain. To prevent the environmentally harmful gas from exposing to atmosphere, the flue gas de-sulfurization (FGD) processes such as limestone-scrubbing and chemical absorption are requested in the fire power plant. Currently, among many sorbents limestone (CaCO3) is widely used for a scrubbing process which utilizes the chemical reaction between CaCO3 and SO2 to give solid CaSO3. As this process gives a large amount of solid waste cakes as by-products as well, the new absorption methods using organic solvents as SO2-removal agents have been explored because the absorbing agents can be regenerated repeatedly.
