Flue gas desulfurization (FGD) is one of the most effective techniques to control the emission of SO2 from the combustion of coal. The by-products of FGD may occupy much land and cause the second pollution. The resourceable technology of FGD changes SO2 from flue gas to sulfur-containing by-product, by which it is possible to solve the problem of desulfurization by-product treatment. This paper reviews the recent development of resurceable technology of FGD with special reference to removal of SO2 from flue gas.
