The objective of this coordinated research program is to obtain the most attractive combinations of acid gas removal, methane separation for the Exxon Catalytic Coal Gasification (CCG) and the Rockwell/Cities Service Hydrogasification processes. The program is divided into nine subtasks with each subtask studying the effect of variation of a key design parameter on the treatment cost of the SNG produced. Progress reports of 8 subtasks are presented. The following are some of the highlights. Subtask 1 - Heat and material balance and equipment sizing was completed for the cryogenic methane separation. The overall material balance is presented in a table. Subtask 2 - Preliminary designs for MEA and DEA gas removal systems were established. Subtasks 3 to 5 - Economic evaluation is in proress. Subtask 6 - The SNG product compressor train was simulated for the case where sufficient SNG fuel is withdrawn from the product compressors to fire the dryer reactivation heater. Subtask 7 - Acid gas removal and cryogenic separation equipment was resized to accommodate Exxon's request for a two-train plant design. Subtask 8 - The Benfield and Selexol systems will be evaluated for acid gas removal.
