Three approaches to pretreatment for the Industrial Fuel Gas Demonstration Plant project in the Institute of Gas Technology (IGT) Pilot Plant have been examined. Analyses of these approaches, selection of the best alternative among the three, and detailed design and evaluation of cost and schedule impacts were made. The best approach available to pretreatment demonstration is an integrated pretreater - an ash agglomerating gasifier (AAG) that uses the existing AAG system, a new pretreater pressure vessel, and needed ancillary equipment. Based on pilot plant results, IGT dos not recommend pretreatment for the Industrial Fuel Gas Demonstration Plant or testing pretreatment in the IGT Pilot Plant, but merely suggests the above approach to pilot plant testing of pretreatment as the most viable. Based on pilot plant tests, IGT does not feel that pretreatment is necessary for operation of the ash agglomerating gasifier with Western Kentucky No. 9 coal. IGT has developed a feeding technique that enables raw coal to be fed directly to the gasifier without plugging of the feed nozzle lines which has been demonstrated in several tests. Should pretreatment prove necessary because of unforeseen circumstances, IGT has studied the available alternatives and has selected the best alternative for detailed consideration. If pretreatment is required, it can be implemented efficiently in accordance with plans developed.
