Columbia pipeline to support Celanese coal-to-gas conversion

Celanese Corp. plans a repowering of its Celco plant in Giles County, Va., converting seven coal-fired boilers to six gas-fired boilers, with the gas boilers due for initial operation in October 2014 and full operation by January 2015.

Celanese on Nov. 29 filed a letter with the Federal Energy Regulatory Commission supporting a pending application by Columbia Gas Transmission LLC for approval of a 12.6-mile, 8-inch diameter pipeline to serve the Celanese Acetate LLC plant. This pipeline would provide 46,000 dth/day of service to the plant.

Celanese noted that the repowering of its plant from coal to gas would cut various emissions, including SO2 and NOx. The manufacturing facility is doing this conversion under the U.S. Environmental Protection Agency’s (EPA) Boiler Maximum Achievable Control Technology Rule.

Celanese urged quick FERC approval of the Columbia application so that it can meet its gas boiler startup schedule.

On April 5, Columbia filed this application with FERC for a Certificate of Public Convenience and Necessity to construct and operate the proposed facilities in Giles County, Va., and Summers and Monroe counties, W.Va. This is referred to as the Giles County Project. Columbia proposes to start project construction in March 2014, and place the project into service in the fall of 2014.

All but 40 feet of the pipeline would be located in West Virginia. The loop would be adjacent to Columbia’s existing 6-inch-diameter “Line KB” for the majority of its length (about 87%) except for a few deviations to avoid construction in congested residential areas. The loop extends from Columbia’s Line KA meter and receipt station to Columbia Gas of Virginia’s Scott Branch point of delivery. Columbia would also construct a mainline valve, a gas heater and a pig launcher and receiver.

The Babcock & Wilcox Co. (NYSE: BWC) said Aug. 20 that subsidiary Babcock & Wilcox Power Generation Group has been awarded a contract to design and supply FM water tube package boilers for the Celanese project.
