Engineering support services for the DOE/GRI coal-gasification research program. Westinghouse risk analysis

OSTI ID:5324305

Kellogg has been requested by DOE to assess the risk involved if the Westinghouse process is scaled-up directly from the 15-TPD PDU to a 70-TPH demonstration plant, bypassing further investigation in a 5-TPH pilot plant. The configuration of the demonstration plant is to be the single gasifier, air-blown, to produce low-Btu gas for use in a combined-cycle power plant. Four gasification trains of 20-TPH nominal capacity each will be employed. Westinghouse gasifier development (prior to the PDU) was in the areas of cold-flow modeling to investigate fluid dynamics, benchscale tests to study reaction kinetics, and analytical modeling to quantify cold-flow and chemical tests data for scaleup. These efforts have continued, with refinements being drawn from PDU tests. At present, a complete gasifier design procedure exists, although some technical issues (primarily involving scaleup) remain to be resolved. The PDU gasifier, which was designed from cold-flow and bench-scale tests, has operated successfully in the air-blown mode. Kellogg's central conclusion is that no significant advantage exists for a 5-TPH pilot plant over the PDU and cold-flow model as tools to resolve the outstanding technical issues for demonstration plant design. The recommendations are generally in agreement with Westinghouse's plans.
