Title: Distribution and quality of carbonate rock for desulfurization in coal combustion processes

Abstract

To meet the requirements of the Federal Clean Air Act of 1970 and the Amendments of 1977 and 1990, coal-burning power plants will use large tonnages of carbonate rock (limestone and dolomite) and lime for flue gas desulfurization, fluidized bed combustion, and other processes designed to minimize air pollution. By January 1, 2000, the end of Phase 2 of Title IV of the Clean Air Act, all plants having a capacity of 25 MW or more must restrict their sulfur emissions to 1.2 lb per million Btu or less. As power companies endeavor to comply with this regulation, they will need to identify resources of limestone and dolomite having specific quality and grindability characteristics, in sufficient quantity for their needs and within proximity to their plants. A study is underway at the US Geological Survey (USGS) to identify limestone resources in the Eastern US that are best suited for desulfurization in the various combustion systems. Carbonate resources are being identified, quantified, and characterized on the basis of their sorbent properties and proximity to potential markets. In addition, the USGS has developed a carbonate data base that includes approximately 1,500 chemically analyzed samples from the US. The current study focuses onmore » limestones that are suited for wet scrubber operations and have at least 90% CaCO{sub 3}.« less
