Hanson Pressure Pipe's South Beloit, Ill., facility is supplying 2,200 ft. of 48- to 90-in.-diameter pressure pipe for underground circulating water systems at a Îcleaner coalÌ power plant in Edwardsport, Ind. The 630-megawatt operation marks the first large-scale application of a coal-gasification system that converts high-sulfur coal to synthetic natural gas.

The integrated gasification combined cycle (IGCC) plant comprises a cleaner and more efficient system that reportedly will provide more than 10 times the power of facilities it is replacing, while emitting less sulfur dioxide and nitrogen oxides, and consuming less water. ÎSyngasÌ generated by the system is used Û after processing to remove sulfur compounds, mercury, and particulate matter Û to fuel a combustion turbine generator that produces electricity. Additionally, the IGCC system holds potential for future carbon-dioxide capture and sequestration.

Construction began last fall, with the IGCC installation phase commencing in January and requiring an additional 1,200 feet of Hanson's concrete pressure pipe in various sizes with numerous fittings. The plant owner projects commercial operation in 2012.
