Unique Missouri Facility Will Process up to 400,000 Tons Per Year
LOUISVILLE, KY (October 13, 2010) – Charah®, Inc., a leading ash management provider for the coal-fired electric utility industry, and St. Louis-based Ameren Missouri today officially opened a limestone grinding facility at APAC Tennessee’s Brickey Quarry located in Bloomsdale, Missouri. The facility will process up to 400,000 tons of limestone annually into powdered limestone for use at Ameren Missouri’s Sioux coal-fired power plant located in West Alton, Missouri. Powdered limestone is used as a reagent to capture sulfur dioxide (SO2) emissions.
The unique project results from a partnership between Charah and Ameren Missouri in which Charah designed, constructed and will now operate the facility for Ameren Missouri to meet the utility’s powdered limestone needs.
The Brickey Limestone Grinding Facility has a series of hoppers and conveyors which are used to move the limestone from a raw material storage building to two 85-inch Williams Patent Crusher roller mills. Once crushed, the limestone is stored in an 8,000 ton storage dome and then conveyed into one of two load-out silos.
According to Charles Price, president and CEO of Charah, “Charah provides a broad base of services to the coal-fired utility industry to assist them in meeting the increasing environmental requirements under which they operate. We are committed to providing our utility partners like Ameren innovative, environmentally conscious solutions to meet all of their ash management and power plant support services needs.”
Financial terms of the agreement were not disclosed.
