The benefits of Wet flue gas desulfurization represent one small step for man--a great leap! First, it removes sulfur dioxide (a major contributor to acid rain and respiratory problems) effectively helping to reduce air pollution. Next: WFGD systems are reliable--its removal rate is high and can make for a clean world. Thirdly, the byproduct, gypsum is valuable and can be used in the building industry, offering an additional revenue stream Along the same lines, when companies put WFGD in place, they can easily meet stringent environmental standards. To meet very stringent environmental standards, generators who switch to WFGD technology will not be penalized under the law. Hence lastly: Lowering SO2 emissions means that the whole community enjoys improved health. The damage to the environment has been overturned, which is good for both short-term and long range profit.
