Westinghouse gasification technology development and projects status
A joint program between Westinghouse, the Department of Energy, and the Gas Research Institute has shown, through the use of a 35 ton-per-day coal feed process development unit (PDU), that the fluidized bed gasifier is technically feasible and economically attractive. The process has been shown to be simple, controllable, and safe in converting many types of coals, including reactive western coals, caking eastern coals, high ash coals, and run-of-mine coals. The process is efficient because it utilizes many coals at high conversion efficiency with relatively low use of oxidant and steam. Because of its simplicity, its use of available hardware technology, and the absence of tars in the product gas, the system has low capital and operating costs. It can be employed with little adverse environmental impact because of its efficiency, low pollutant output, low water usage, and disposal ash product. Process advantages have been confirmed by independent conceptual designs and cost estimates for commercial-scale applications, including substitute natural gas (SNG), industrial fuel gas, liquid synfuels, and combined cycle power generation. The development program includes unique cost-effective integration of hot and cold small-scale experimental models, a commercial-scale cold flow model, and analytical modeling, together with the PDU, to provide commercial design procedures. Westinghouse commercial designs are utilizing these design tools and the process is now being scaled-up for a commercial-scale demonstration facility.
