摘  要：順酐是一種極其重要的有機化工原料，現(xiàn)在已成為世界第三大有機酸酐。由于順酐很容易通過光化、加成、酯化、加氫等反應(yīng)生產(chǎn)出眾多的下游產(chǎn)品，被廣泛應(yīng)用于不飽和聚酯樹脂及其制品、涂料、工程塑料、醫(yī)藥、農(nóng)藥、添加劑等領(lǐng)域，開發(fā)利用前景十分廣闊。

　　　本設(shè)計采用固定床糠醛氧化法生產(chǎn)順酐，主要生產(chǎn)過程包括：（1）固定床氧化；（2）部分冷凝；（3）經(jīng)水吸收；（4）二甲苯脫水；（5）精制，并對其進行了物料衡算、熱量衡算、設(shè)備選型、管道計算、經(jīng)濟估算。

　　　本設(shè)計中繪制了帶控制點的工藝流程圖、物料平衡圖、車間平面布置圖和關(guān)鍵設(shè)備條件圖。

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.
