An Illinois scientist believes he has found a way to help coal gasification power plants like the Wabash River plant in Terre Haute, Ind., remove sulfur emissions while significantly cutting capital costs and increasing power plant revenues. Jim Swisher, E&A Associates chief scientist and partner, expects to know for sure very soon when seven tons of his zinc titanate pellets-a sulfur absorber that can be cleaned and reused perhaps 1,000 times-receive long-term performance testing at a General Electric coal gasifier in Schenectady, NY. Coal gasification, one of the nation`s most promising clean coal technologies, turns high-sulfur coal into low-sulfur coal gas. The problem with the process is that the coal gas, which is produced at temperatures that exceed 2,300 F, must be cooled to room temperature (about 70 F) before the sulfur can be removed.
