Coal gasification/gas cleanup fuels plants for synthetic fuel applications must be developed within two sets of constraints: one imposed by dynamic load response to variations in end-use demand, the other by the need to comply with environmental regulations. The overall objective of the program is to establish the technology base required to operate within those constraints. In order to establish that base, system and component performance of the fuels plant are being characterized in both steady state and dynamic operation; and the information required to establish system control logic is being developed. An integrated coal gasification system composed of proven process units (i.e., a Process Evaluation Facility - PEF) at the contractor's site is being used to perform tests for establishing an information base to: establish performance parameters for each process unit; define dynamic interactions of process units operating under variable loads; characterize effluent flow streams from the process; and develop an experimentally verified simulation model for integrated system operations. The combined experimental-analytical approach employed will yield empirically verified performance projections for full-scale systems. Accomplishments for this past quarter are presented for the following six tasks: (1) test program definition and analysis; (2) facility operation; (3) system modeling; (4) component support requirements; (5) fuel system modifications; and (6) program management.
