3. 设计原则
原则： （1） 安全：化工生产中大量物质是易燃、易爆或者有毒性的。因此，设计必须充分考虑各种明显的和潜在的危险，保证生产人员的健康和安全。
（2） 操作方便：在确定各个生产过程及设备的同时，还要合理确定操作条件。因为它对生产过程与设备的确立及其作用的发挥和控制方案的确定，都有直接关系。
（3） 投资省：即要求经济地使用设备投资、土建投资、公用工程投资和人力成本。
（4） 便于安装：工厂布置应满足施工和安装作业要求。特别是应考虑大型设备的吊装，厂内道路的路面结构和载荷标准等应满足施工安装的要求。
主要设计指标：
生产能力：年产5.5万吨的聚氯乙烯
年工作日：以300天计算
转化率为85%

Project: An annual output of 55,000 tons of PVC Process Design
PVC is the world's first industrial production of the plastic varieties，is widely used in agriculture , petrochemicals , light industry , textile, chemical building materials , electric power, metallurgy , defense industry, building materials, food processing and other national economic lifelines sector, with flame retardant , abrasion resistance, chemical resistance, high mechanical strength and excellent electrical insulation and so on. PVC production process has a crucial role in the development of the modern economy .This design is on annual output of 55,000 tons of PVC polymerization process for the preliminary design section . Its use of calcium carbide acetylene Preparation of vinyl chloride . This method carbide as the raw material, the production of acetylene which is hydrolyzed , the chlorine and hydrogen generated in chlor-alkali production by direct synthesis method hydrogen , acetylene and hydrogen purification reformer into synthetic crude vinyl chloride monomer. The crude obtained after distillation of vinyl chloride monomer fine vinyl chloride monomer to be polymerized through the suspension to give polyvinyl chloride. After determining the method of production of PVC production process technology for material balance, heat balance calculation and equipment selection .
The chemical industry is an important industry of the national economy. It has very close links with other industrial The chemical industry plays a very important role in the promotion of agriculture, textile industry, mechanical industry, materials industry, transportation, energy industry, defense industry, as well as culture and science and technology, especially the development of cutting-edge technology.
With the rapid development of China's chemical industry, chemical engineering design work plays a very important role in chemical production, scientific experiments and chemical building.
1.Chemical production
The design of the new plant has been put into the modification or extension of factory production, and improve the existing process, simplify the production process, to discover and solve the problems in the production and mining production potential and need to correct design ideas and design techniques.
