文档介绍：年产10万吨聚丙烯的工艺设计
摘要
聚丙烯是丙烯单体聚合而形成的高分子聚合物,是一种通用合成树脂。它作为一种高分子塑料,在现代化工生产中占有重要的地位,是五大工程塑料之一。
聚丙烯之所以是各种聚丙烯烃材料中发展最快的一种,关键在于其催化剂技术的飞速发展。本设计中就详细介绍了聚丙烯随催化剂的发展而发展的情况。
本设计是以中原石化的S-PP工艺为设计基础,设定年产量为两万吨,然后进行物料衡算、热量衡算、设备选型等过程,最终完成的一份比较完整的设计说明书。
另外聚丙烯来源丰富,价格便宜,易于加工成型,产品综合性能优良,因此被广泛地应用于化工、化纤、轻工、家电、建筑、包装、农业、国防、交通运输、民用塑料制品等各个领域,在聚烯烃树脂中,是仅次于聚氯乙烯、聚乙烯之后的第三大通用塑料。

ABSTRACT
Polypropylene is a generic synthetic resin ,which is polymerizated by propylene monomer .As a polymer plastic, in the modern chemical production it occupies an important position and was one of the five major engineering plastics.
Polypropylene is the fastest developing material in variety of hydrocarbon materials .The key reason is the catalyst’s rapid development. This design introduced polypropylene’s development with the development of catalyst.
The design is based on the Zhongyuan Petrochemical S-PP technology and set for 20,000 tons of annual output .Then proceed to the material balance 、 energy balance and equipment selection, Finally reached a plete design specification.
Another, Because of its rich resource, low price, easy to process takes shape, fine productoverall performance,therefore it is widely applied to chemical,the chemical fiber, the light industry, the electrical appliances, the building, the packing, agricultural, the national defense, thetransportation, the civil plastic product and so on. In the polyolefine resin,it is only inferior after the PVC、PE the third general plastic.
