Turn in the road: chemicals from coal
This paper describes a new process and equipment developed by Eastman Co. for the production of acetic anhydride and other chemicals from coal by using coal gasification route. First, a research program was begun to synthesize acetic anhydride on a bench-scale. The main emphasis was the development of suitable catalyst to produce acetic anhydride from the lowest-cost starting materials, with a minimum of by-products, and under conditions easily achievable in commercial production. Continuous pilot plants of modest size were built in 1977 to test various materials of construction and to demonstrate that the rather expensive catalyst system which had been developed could be reused indefinitely. The data from the pilot operations were used to formulate mathematical models for the conceptual flowsheet design. The process was scaled up to the full-sized commercial plant, and the math models aided in optimizing the final engineering design. The gasification complex, will include a Texaco coal gasification plant for syngas manufacture, raw gas clean-up and separation facilities, a sulfur recovery unit, a coal-fired steam plant with electric power cogeneration, and chemical plants to produce methanol, methyl acetate, and acetic anhydride. The plant will gasify approximately 900 ton/d of high-sulfur coal from nearby mines. Economic considerations are included.
