文档介绍：年产6万吨环氧树脂车间工艺设计
设计说明:
环氧树脂生产工艺一般分为一步法和二步法。目前低分子量液体环氧树脂和中分子量固体环氧树脂,一般都采用一步法工艺;高分子量环氧树脂采用二步法。
本设计用一步法工艺:把双酚A(BPA)和环氧氯丙烷(ECH)在氢氧化钠作用下进行缩聚,即开环和闭环在同一反应条件下进行的工艺方法。
以双酚A(BPA)为主要原材料,合成的环氧树脂称为双酚A(BPA)型环氧树脂,是目前产量最大、用途最广的环氧树脂,由于它的应用遍及国民经济的众多领域,因此又称为通用型环氧树脂。本设计用此类环氧树脂。
本文从生产工艺技术、经济、管理等方面对年产6万吨环氧树脂进行了详细的论述,内容主要包括:设计依据,工艺路线论证,工艺流程设计,全流程物料衡算,全流程能量衡算,工艺设备选型与计算,车间布置设计,三废处理及其综合利用等。

Annual output of 60 000 tons of epoxy resin plant process design
Design Notes:
Epoxy resin production process is generally divided into one-step and two-step. Present in low molecular weight solid epoxy resins and liquid epoxy resin, generally using one-step process; high molecular weight epoxy resin with two-step.
This design one step process: the bisphenol A (BPA) and epichlorohydrin (ECH) in the condensation under the action of sodium hydroxide, the open-loop and closed-loop in the same reaction conditions for process design of the use of such epoxy resin.
To bisphenol A (BPA) as the main raw material, known as bisphenol epoxy resin
synthesized A (BPA) type epoxy resin is the output of the largest and most widely used epoxy resin, because of its application throughout the national economy many areas, so-called general epoxy resin. It is ether type.
In this paper, production technology, economics, management and other aspects of an annual output of 60 000 tons epoxy discussed in detail, mainly including: the design basis, process route feasibility studies, process design, the whole process material balance, the whole process of energy accountancy, process equipment selection and calculation, plant layout design, waste treatment prehensive utilization.
