Engineering support services for the DOE/GRI coal-gasification research program. Evaluation of the IGT Peatgas PDU data base
As requested by DOE, Kellogg has reviewed the data base generated by IGT for the Peatgas process during laboratory and PDU testing. Kellogg's central finding, from the review reported here, is that the existing data base contains sufficient evidence to warrant further evaluation of the Peatgas process at pilot plant scale. The existing data base relates to testing with peats from (primarily) Minnesota, North Carolina and Maine. Thermobalance studies were employed to define a few kinetic parameters, i.e., the rate of base carbon conversion. Numerous tests using a small coiled-tube reactor and the lift-line PDU were conducted to investigate hydrogasification, where hydrogen or a steam/hydrogen mixture was the reactive gas. A fluidized bed PDU was employed to investigate steam-oxygen gasification and fluidization relationships were studied. The primary advantages to be gained by Peatgas pilot plant testing are, in Kellogg's opinion, the demonstration and evaluation of the three process stages (drying, hydrogasification and steam-oxygen gasification) in an integrated mode. The lack of integrated operation is a significant shortcoming of the existing data base and as such Kellogg would not recommend use of the data base for purposes other than pilot plant design and preliminary engineering studies. Other more specific comments regarding the data base are given.
