Abstract：Maleic anhydride(MA) is a kind of raw material which is of much importance to organic chemical engineering. MA can be easily dissolved in water, organic solvent of acetone, ethyl acetate and so on, so it is widely used in the fields of resin, paint, agriculture, lubricant, paper dealing agent and food additive etc. Therefore，it is promising for development and utilization as good chemical resources．

　　　MA is produced in fixed-bed by the technology route of furfural oxidation. The process includes steps as following: (1)fixed-bed oxidation; (2)part condensation; (3)water absorption; (4)dehydrated by Xylene;(5)refined. The technology designs of MA production for the whole process are prepared according material balance, energy equilibrium, equipment choice and economic estimate.

　　　The flow charts as PID, PFD, factory layout diagram and the layout chart of workshop with equipment are drawn in this design.
