17万吨聚碳酸酯生产毕业设VIP专享

年产 17 万吨的耐磨聚碳酸酯的工艺设计摘 要本设计的生产目标是每年生产 17 万吨耐磨聚碳酸酯，本文设计合理的生产系统利用界面缩聚法进行生产。从合成聚碳酸酯、光气化反应、缩聚、后处理几个步骤来设计工艺流程，并进行物料衡算、热量衡算以及设备选型。以经济、高效、切实可行为设计理念，进行工厂的整体设计。同时本文有对生产过程中的厂区布置进行成本及利润核算并对“三废”处理作了相关说明，而且绘制了相应的设计图纸，设计图纸包括主要设备图、工艺流程图。关键词:聚碳酸酯,界面缩聚,光气法,双酚 AProduction process design of 170000t / a wear-resistant polycarbonateAbstractThis design is mainly based on the production target of 170000 tons of wear-resistant polycarbonate per year, design a reasonable production system, and use the interface polycondensation method to produce polycarbonate. The technological process is designed from the steps of synthesis of polycarbonate, phosgene reaction, polycondensation and post-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 and practical design. At the same time, the design describes the cost and profit accounting, plant layout, three waste treatment in the production process, and draws the corresponding drawings, such as process flow chart, main equipment and charts.Keywords：polycarbonate, interfacial polycondensation, phosgene method, bisphenol A目录1 前言..........................................................................................................................................11.1 聚碳酸酯简介..............................................................................................................11.2 聚碳酸酯的应用..........................................................................................................11.3 聚碳酸酯在国内外的发展概况及存在的问题..............
