[Passamaquoddy Technology Recovery Scrubber{trademark}, March 1992]
The Passamaquoddy Technology Recovery Scrubber{trademark} has been built and is being demonstrated on-line at the Dragon Products Plant in Thomaston, Maine. This Innovative Clean Coal Technology is using waste cement kiln dust (CKD) to scrub sulfur dioxide, some NO{sub x}, as well as a small amount of carbon dioxide from a coal burning kiln exhaust flue gas. The process also enables the cement plant to reuse the treated CKD, eliminating the need to landfill this material. Potassium, the offending contaminant in the CKD, is extracted in a useful form, potassium sulfate, which is used as a fertilizer. These useful products generate income from operation of this Recovery Scrubber. System start-up was begun in late December of 1990. At that time, several mechanical problems were encountered. These relatively minor problems were resolved enabling Phase III to begin on August 20, 1991. While inefficiencies are still being worked out, major program objectives are being met. Resolution of remaining operability problems is well in hand and should not hamper attainment of all project goals.
