Conceptual Designs of Commercial Plants:Coal to Methanol and Methanol to Gasoline. Quarterly Technical Progress Report,August 1, 1977--October 28, 1977.

摘要

An analysis of the work accomplished during this period establishes the following conclusions: (1) Indications are promising that injection extruders can be developed within the next two years to feed dry coal and lime up to system pressures of 1,000psig. A feeder capacity of 100tons per hour seems to be within practical limits. (2) The emergency relief and venting system for the commercial plant is primarily handled by three 200-foot flare stacks for each gasifier train. (3) The results of preliminary studies warrant further investigation into the possibilities of marketing carbon dioxide and nitrogen as salable by-products. (4) Assuming the proposed commercial plant is located in Southern Appalachia,it is more attractive to purchase the required power instead of onsite power generation. (5) The Methanol-to-Gasoline conceptual design study is proceeding based on the following schemes:Gasoline plus by-product LPG;gasoline plus by-product LPG and high Btu gas;and maximum gasoline. Schemes A and C will be integrated with the Coal-to-Methanol complex whereas Scheme B is simply added to the back-end of the Methanol Complex. (ERA citation 03:044044)
