一、概述硫酸二甲酯是重要的化工原料,它在生产过程中易燃、易爆,剧毒,所以对它的生产过程进行自动控制显得非常必要。该项目是重庆市科委下达的微机推广应用重点科研项目。二、控制原理及硬件配置从硫酸二甲酯生产工艺来看,醚化工段是影响原料消耗、产量的重要岗位。因此,本系统的主要作用是将醚化反应温度控制在最
First, an overview of dimethyl sulfate is an important chemical raw materials, it is flammable in the production process, explosive, highly toxic, so it is necessary for the production process of automatic control. The project is issued by Chongqing Municipal Science and Technology Commission to promote the application of key scientific research projects. Second, the control principle and hardware configuration Dimethyl sulfate from the production process point of view, etherification section is affecting the consumption of raw materials, production of important positions. Therefore, the main function of the system is to control the temperature of the etherification in the most
