精馏塔设计外文翻译内容摘要：

is difficult to volatilize liquid transfer by steam, steam, liquid phase mass transfer between processes. This design is stupid chlorobenzene continuous separation of distillation tower, and is a important basic raw material of anic synthesis, used as a dye, medicine, pesticide, anic synthesis in the manufacture of 河北联合大学 6 phenol, nitrochlorobenzene, two nitrochlorobenzene, aniline, nitrophenol and insecticide DDT, also used as ethyl cellulose and many resin of downstream products, nitrochlorobenzene is the main consumer of chlorobenzene, nitrochlorobenzene is of vital dyes, pesticides, pharmaceutical order to nitro chloridize benzene as raw materials to production of pnitrophenol, pnitroaniline, amino phenol, benzene two amine, paminophenol methyl ether and amino benzene ether and a series of anic chemical as a result of Using Benzene Chlorination of chlorobenzene, benzene and chlorobenzene miscible, so we need to design a distillation column used for the separation of volatile benzene and not easy to volatilize and chlorobenzene. First of all, benzene and chlorobenzene raw material in the raw material preheater of heating to boiling point, then, from raw materials into the feed inlet into the distillation of being heated to boiling point, a mixture of both gas phase mixture, and the mixture in liquid phase, when the raw material mixture was separated from the gas mixture, in the distillation tower rises, and the liquid mixture in distillation tower in phase mixture to rise to the top of the tower at the top of the condenser, the vapor mixture is cooled down to the bubble point, wherein the liquid portion into the top product cooler, stop for a certain time and then into benzene storage tank, and wherein the gaseous ponent back into the distillation tower, this process is called phase mixture from the bottom of the tower into a portion to the bottom of the tower product cooler, one part enter。
