摘要
在化工行业的DCS系统控制中,常采用不同的过程控制系统,以满足生产工艺的要求。安徽铜陵六国化工公司年产30万吨的合成氨项目采用了HONEYWELL EPKS 300系列DCS控制系统。对该系统通常使用的单回路反馈控制、串级控制、分程控制、比值控制等几种典型的控制方案及其应用进行了研究和讨论。
In DCS control of the chemical industry, the different process control systems are adopted to meet the requirements of the various production processes. The synthetic ammonia project with an annual output of 300000 tons of Anhui Tongling Liuguo Chemical Company adopts the HONEYWELL EPKS 300 series DCS control system. The several typical control schemes and the applications of the single loop feedback control, the cascade control, the split ranging control and the ratio control are discussed and studied.
