Catalytic reduction of SO[sub x]-NO[sub x] in coal flue gas
Almost half of the coal purchased by the utilities that year was not Ohio coal. The 20-plus million tons/year of non-Ohio coal consumed by Ohio generators is an indication of the order of magnitude of the potential market incentive for Ohio to supply its power plants from its indigenous coal mine. The major reason for the drop in Ohio coal production rate is that the average content of Ohio coal is 3.5 weight percent, with a range of one to six percent. Use of high-sulfur coal introduces environmental problems due to the high SO[sub 2] emission rate in the boiler flue gas. Potential solutions include use of alternative low-sulfur non-Ohio coal and addition of SO[sub 2] (and NO[sub x]) removal facilities. The substitution of non-Ohio low-sulfur coal for Ohio coal is a strong negative for the state and its coal mining industry; it means further shrinkage of the state's coal industry accompanied by loss of Ohio jobs. The Parsons FGC process is a candidate for the alternative solution, i.e., to provide high efficiency post-combustion removal of SO[sub 2] (and NO[sub x]). The Phase 2 pilot plant test results have demonstrated that the Parsons FGC process is capable to remove 99-plus percent of SO[sub 2] and 95-plus percent of NO[sub x] from coal-fired boiler flue gas. The Parsons FGC process will permit Ohio coal fired power plants to burn high-sulfur Ohio coal and achieve conformance with provisions of the Clean Air Act Amendments of 1990. Because SO[sub 2] reduction using the Parsons FGC process will be greater than the amendment requirement, its use will provide the affected Ohio power plant with marketable net allowances having a definite economic value.
