摘要
C9石油树脂是以乙烯装置副产的裂解C9馏分为主要原料制成的高分子化合物,是一种浅黄色至暗褐色的功能性树脂。相对分子量一般为200~3 000,常温下为玻璃态热塑性固体。我国C9资源比较丰富,目前主要用作燃料或廉价出口。因为具有增粘性、可塑性、脆性、粘结性及与其他树脂的相容性好的特点,广泛应用于胶粘带、热熔胶、油漆、油墨、涂料、粘合剂、橡胶等行业。
目前,生产普通的C9石油树脂主要有三种方法:催化聚合,热聚合,自由基引发聚合。本工艺采用的是阳离子催化聚合,催化剂是 AlCl3.。原料经过换热器换热后,达到反应需要的温度,进入聚合反应釜,再依次进入水洗釜水洗,静止分离罐分离,减压蒸发器蒸馏,最后得到溶剂油和石油树脂。在本设计中,查阅了很多文献,在前期编写了文献综述和外文文献的翻译。通过这些文献和有关书籍,编写了设计计算书,其中包括了物料衡算,热量衡算,和设备选型计算,并且初步确定了工艺流程的草图。在设备选型中,选出了三个原料储罐,三个反应釜,一个水洗釜,一个列管换热器,一个套管换热器,一个静置分离罐,一个减压蒸馏装置,还有两个产品储罐和两个溶剂油储罐。通过查阅书籍和指导老师的指导,对工艺流程图进行了反复的修改。参考工艺流程图和计算,绘制了车间布置图,管道布置图。最后参考相关文献和规定,编写了设计说明书。

Abstract
C9 petroleum resin is a polymer that ethylene byproducts pyrolysis C9 fraction as the main raw material , is a pale yellow to dark brown functional resin. Relative molecular weight is generally 200 to 3000, room temperature thermoplastic glassy solid. C9 resources of our country is rich, now mainly used as fuel or cheap exports. Because with increasing viscosity, plasticity, brittleness, adhesion and patibility with other resins and , widely used in adhesive tapes, adhesives, paints, inks, coatings, adhesives, rubber and other industries.
At present, the production of ordinary C9 petroleum resin is mainly in three ways: the catalytic polymerization, thermal polymerization, radical polymerization. This process is used in cationic polymerization, the catalyst is AlCl3. Through the heat exchanger material to reaches the reaction desired temperature, into the polymerization reactor, then turn into the washing vessel and washed, separated by the stationary separation tank, distillation by under reduced pressure evaporator, resulting solvent oil and petroleum resins. In this design, by the access to a lot of literature, written
