年产17万吨的耐磨聚碳酸酯的工艺设计

Production process design of 170000t/a wear-resistant polycarbonateAbstractThis design is mainly based on the production target of 170000 tons of wear-resistantpolycarbonate per year,design a reasonable production system,and use the interfacepolycondensation method to produce polycarbonate.The technological process is designedfrom the steps of synthesis of polycarbonate,phosgene reaction,polycondensation andpost-treatment,and the material balance,heat balance and equipment selection are carried out.To carry out the overall design of the factory with the concept of economic,efficient andpractical design.At the same time,the design describes the cost and profit accounting,plantlayout,three waste treatment in the production process,and draws the correspondingdrawings,such as process flow chart,main equipment and charts.Keywords:polycarbonate,interfacial polycondensation,phosgene method,bisphenol A
