In addition to its high investment yields, the FGD technology also has significant environmental benefits. With FGD, the release of sulfur dioxide is greatly reduced, greatly diminishing the probability of damage from acid rain to water sources and eliminating many other problems. In The Coding Of FGD Flue Gas Desulfurization, Switzerland The Future Improvement Like It Is Secondly, it decreases the disease-causing properties of the gas (like SO 2 ) which can be created in one of two ways: dragging down potassium permanganate and placing it under a falling chimney or letting untreated waste gases mix with air from the ground. Thirdly, helping businesses comply with the strict but necessary environmental requirements, power plant FGD systems enable them to avoid legal penalties and improve their corporate image at the same time. Fourthly, FGD technologies can be incorporated on top of existing power plants without any major disruptions, thereby ensuring a smooth transition to operations that use less emissions.
