After the influence factors of synthesis process discussed, the production of acetic anhydride process route and related parameters are determined, and the material balance and heat balance of main equipments were calculated. Based on this, the equipments selection, workshop layout and economic accounting were accomplished. In addition, the protection of fire, lightning, poison and three wastes treatment recovery plan were simply discussed. Finally the process flow chart with control point, the figure of main equipments and workshop layout were drawed.
