年产10万吨环氧丙烷生产工艺设计

Production process design of annual production of 100,000 tons ofpropylene oxideAbstractThe design theme of this design is the production process design of 100,000 tons ofpropylene oxide annually.The preparation method selected this time is the HPPO method(direct oxidation method).The HPPO method uses propylene and hydrogen peroxide asreaction raw materials and methanol aqueous solution.After mixing,the epoxidation reactionis carried out in the reactor to produce propylene oxide and water.This design specification has a total of 8 chapters,which respectively list thecharacteristics of different production processes for obtaining propylene oxide products.Atthe same time,the most suitable process for producing propylene oxide is selected from avariety of different methods.This production process is carried out In addition to materialbalance and energy balance,non-standard equipment in the production process was alsocalculated and equipment selected,the location of the plant producing propylene oxide wasselected,and the plant layout and workshop layout were designed.Finally,the non-processdesign in this design is explained.Keywords:Propylene oxide;technological design;Process flow;HPPO method;Directoxidation目录1绪论.11.1.概述及设计意义…1.1.1世界环氧丙烷供需分析1
