feb 14, 2016 sulfur dioxide removal. there are no combustion strategies that can be used to control the generation of sulfur dioxide in PC plants. If sulfur is present in coal it will be converted into sulfur dioxide during combustion. the only recourse is to capture the sulfur, either before the coal is burned using a coal-cleaning process, or after combustion using some chemical reagent inside the power plant.phase reduction-oxidation processes to remove sulfur. while these processes removed essentially all of the sulfur and offered a lower capital cost, they also imposed high chemical and operating costs too costly for many small fuel processing plants. innovating solutions
