金币不多，还求大家帮忙！ 1.2万吨/年CPE-H135生产工艺设计 摘要：概括介绍了氯化聚乙烯的性能、应用、合成工艺、市场前景。介绍了氯化聚乙烯的三种生产工艺：溶液氯化工艺，水相悬浮工艺，固相氯化工艺（又分为搅拌床固相氯化工艺和沸腾床固相氯化工艺）。通过对国内外氯化聚乙烯（CPE）的各种生产方法和生产工艺的特点分析对比，并在有关单位进行了认真实习，收集了大量的设计参数和资料，决定采用水相悬浮法对1.2万吨/年氯化聚乙烯（CPE-H130）项目进行工艺设计。 选择了较为合理的生产厂址，确定了氯化聚乙烯生产配方、工艺操作系数及生产控制指标，对整个生产工艺进行了物料衡算，并对氯化反应釜进行了热量衡算，重点对氯化反应釜及其搅拌装置进行了结构设计，确定采用16MR/TA2+Zr702材料并以钛、钽复层加工制造的氯化反应釜，对生产流程中其它辅助设备进行了选型，并对生产过程中所产生的酸性废水、含氯尾气处理进行初步设计。编写了1.2万吨/年CPE-130生产工艺设计说明书。 关键词：氯化聚乙烯；水相悬浮法；工艺设计 |

12,000 tons / year CPE-H135 production process design Abstract: an overview of the performance of the CPE, application, synthesis process, the market prospects. Introduced three types of chlorinated polyethylene production process: chlorination process solution, aqueous suspension technology, solid-phase chlorination process (further divided into mixed-bed solid-phase chlorination process and boiling-bed solid-phase chlorination process). At home and abroad through the chlorinated polyethylene (CPE) of various production methods and production technology analysis and comparison of the characteristics and the relevant units in the practice seriously, the collection of a large number of design parameters and information, decided to adopt the method of aqueous suspension of 1.2 10,000 tons / year of chlorinated polyethylene (CPE-H130) for process design projects. Chose the more reasonable of the production site, identified the production of chlorinated polyethylene formulations, process operation and production control coefficient of the entire production process for the material balance, and a chlorination reactor heat balance, with a focus on the chlorine reactor and the mixing of the structural design of devices to determine the use of 16MR/TA2 + Zr702 materials and titanium, tantalum stratified chloride manufacturing reactor for the production process of other auxiliary equipment selection, and production generated by the process of acid waste water, chlorine gas to deal with a preliminary design. The preparation of a 12,000 tons / year CPE-130 production process design specification. Key words: chlorinated polyethylene; aqueous suspension method; Process Design |
