聚氯乙烯做为主要通用塑料品种之一,在五大塑料中产量位于第三位。广泛应用于各行业。在PVC树脂生产过程中， 氯乙烯（VCM）生产工艺的技术水平直接影响着PVC树脂的质量、生产成本及市场竞争力。由于历史原因，国内利用电石乙炔法生产VCM占较大比例，但该工艺污染严重，生产成本高，本设计采用目前世界流行的乙烯氢氧化法。该工艺生产成本低，稳定，适合大规模生产，本设计详细介绍了VCM生产的各工艺单元并对其进行了优化。
氯乙烯的聚合方法，有溶液聚合、本体聚合、乳液聚合和悬浮聚合。悬浮法聚合工艺成熟、操作简单、生产成本低、经济效益好、应用领域宽，一直是生产PVC树脂的主要方法。目前，悬浮工艺的聚氯乙烯产量占80%以上，品种之多，产量之大是其他工艺所无法相比的。
本设计详细介绍了PVC悬浮聚合的工艺流程与控制，对悬浮聚合各工段物料及能量进行了衡算。
目前，PVC行业采用大型聚合釜生产装置已成为近年来明显的发展趋势，本设计对100m3聚合釜进行了详尽的介绍与研究。

PVC plastics as a major common species in one of the five major plastics production in the third place. Widely used in various industries. PVC resin in the production process, vinyl chloride (VCM) production process technology is directly affecting the quality of PVC resin, production costs and market competitiveness. Due to historical reasons, the use of calcium carbide acetylene domestic production accounted for a larger percentage of VCM, but the process seriously polluted, High production cost, the design of the current pop world ethylene hydroxide law. The technology to produce low-cost, stable and suitable for mass production. The detailed design of VCM production of the modules and its optimization.
Vinyl chloride polymerization method, solution polymerization, bulk polymerization, emulsion and suspension polymerization. Suspension polymerization process maturity, simple operation and low cost of production, good economic returns, the wide field of application, has been
