DCS在聚苯乙烯装置中的应用

Application of the DCS in Polystyrene Plants

一、前言分散控制系统(DCS)硬件设备配置灵活,安全可靠性好,而且能够通过应用各种先进的控制方案,开发管理软件取得较高的经济效益。因此DCS成为过程控制计算机的主要形式,在工程设计中占有重要的地位。 DCS的设计是工程设计中的一项新的工作。它继承了传统模拟仪表系统设计的诸多概念,但是又有其独自的特点。

Programming of utility package for the DCS that are used for polystyrene plants in the Yanshan Petrochemical Industry Corp. in Beijing is introduced in this paper. Relating the practice detail discussion on the application techniques of the DCS and the contents and programming of its utility software is also given here.
