Abstract |
Among the more than 50 desulfurization control processes which have been proposed, these are considered to be sufficiently well characterized to potentially make a significant contribution to SO2 control within the next 5 years: wet lime/limestone scrubbing process, wet magnesium oxide scrubbing, and catalytic-oxidation. The various control processes are compared with each other in terms of removal efficiency, capital and operating costs, and with low-sulfur fuel in terms of operating costs. It appears that the three control processes discussed offer an economic incentive for utilization over low-sulfur fuel for many power plants, although power plant location and the fossil fuel type utilized strongly affect any comparison. |
