4万t/a 醋酐生产工艺设计
摘要
醋酐是重要的有机化工原料,涉及各个领域并对社会的发展起着重要的作用,因此制备醋酐成了工业生产的重要工作,目前工业上生产醋酐主要有三种方法:乙醛氧化联产法、乙烯酮法和醋酸甲酯羰基合成法。虽然醋酐的应用广,实用强,但是如不适当处理及储存就会对环境有危害,对水体造成污染,严重时可危机人的生命。
通过对醋酐生产的研究,目前较适合推广及环保的生产是醋酸甲酯羰基化合成法,该方法不仅符合未来的发展趋势,在成本方面也大大降低了投资,是目前生产醋酐最具前景的方法。考虑到生产醋酐的意义及应用前景,进而提出了生产醋酐的具体工艺流程和设备的选型。

With an Annual Output of 40 Thousand t/a Acetic Anhydride Production Process Design
Abstract
Acetic anhydride is the anic chemical raw materials, involving various fields and on social development plays a important role, therefore of preparation of acetic anhydride into the important work of industrial production, the industrial production of acetic anhydride are three main methods: oxidation of acetaldehyde generation method, ethylene ketone method and acetic acid methyl ester carbonyl synthesis method. Although the wide application of acetic anhydride, practical strong, but if not properly handle and store it is harmful to the environment, the water pollution caused by serious crisis of human life.
Through the study of acetic anhydride production. It is suitable for promotion and environment-friendly production is acetic acid methyl ester pound method, this method not only conforms to the trend of development in the future, in terms of cost is also greatly reduced the investment, the acetic anhydride production the most promising method. Considering the production of acetic anhydride significance and application prospect, and puts forward the specific selection of acetic anhydride production process and equipment.
