The output will be 1×104 t/y. Through the comparison and evaluation of kinds of different routs we select an advanced and economic route in both domestic and overseas. Benzene acts as row material and V2O5as catalyst. Reactants transform to production after reacting in a fixed-bed reactor. The mixture production is first cooled in a heat exchanger and then refined through intermittent azeotropic distillation and reduced pressure distillation. Finally the production MA is obtained.Material balance and heat balance are conducted. Material calculation and checking of the key equipment production-tower are made using the empirical method. Besides, calculation and selection of part equipment are conducted. According to the depth of the construction drawing and design specification ，PID 、equipment assembly drawings、workshop layout diagrams and piping layout drawings are given. Effectively energy saving method and measures are put forward. Economic feasible scheme are proposed for the recycle of by-products and the treatment of three wastes. Specific workshop safety management measures are came up with. The work prepares for the investment and construction with detailed drawings and material.目录第一章概况一、车间概况与特点1.车间设计生产规模车间设计生产能力为年产10000吨一级顺酐产品2.生产方法及路线的选择与确定目前工业上常用的顺酐生产方法主要三种：苯氧化法、丁烯氧化法和正丁烷氧化法。苯氧化法生产的基本原理为苯蒸汽与空气（或氧气）在V2O5-MO2O3等活性组分及α-AL2O3等载体组成的催化剂上气相催化生成顺酐，其反应如下：主反应：C6H6+4.5O2→C4H2O3+2C
