随着石油、化工生产自动化水平的提高,现场操作岗位及人员日趋减少。为了便于控制室操作人员对生产过程中出现的异常现象迅速地做出正确判断和处理,安全生产自控系统的设置是必不可少的。本文仅以我们厂的二个应用实例来探讨一下安全生产自控系统中的一些问题,供大家参考。一、真空精馏塔的安全生产自动控制系统本厂DMT精馏塔是一个真空精馏塔,压力控制直接关系到整个精馏过程的运行和产品的纯度。其控制系统如图一所示。安全
With the improvement of the automation level of petroleum and chemical production, the number of on-site operation personnel and staff is decreasing day by day. In order to facilitate the control room operators on the production process anomalies to quickly make the right to judge and deal with the production safety control system is indispensable. This article only to our factory two application examples to explore some of the problems in production safety control system for your reference. First, the vacuum distillation column safety automatic control system Our DMT distillation column is a vacuum distillation column, the pressure control is directly related to the operation of the entire distillation process and product purity. The control system shown in Figure 1. Safety
