Coal gasification/gas cleanup fuel plants for synthetic fuel applications must be developed within the constraints imposed by dynamic load response to variations in end-use demand arid compliance with environmental regulations. The overall objective of the program is to develop the technology base that is required to permit coal conversion systems to operate within the constraints imposed by end-use applications. The fuel plant performance and component as well as end-use interactions will be characterized in both steady state and dynamic operations. The information required to establish system control logic will be developed.
