Coal cleaning as a sulfur reduction strategy in the Midwest
Results of a detailed analysis of SO/sub 2/ reductions achievable through deep physical coal cleaning (PCC) at 20 coal-fired power plants in the US mid-west are presented. The plants are all of greater than 500 MW(e) capacity, are without FGD systems and burn coal of over 1% sulphur content. Their aggregate emissions of 2.4 million tons of SO/sub 2//year represent 55% of the SO/sub 2/ inventory for these States. The SO/sub 2/ reductions that would result from deep cleaning of each coal supplied were calculated, and the costs of the process were estimated. The costs of FGD systems designed to remove the same amount of SO/sub 2/ were also estimated. On this basis, PCC was more cost-effective than FGD for about 50% of the plants studied and had comparable costs for another 25% of the plants.
