先进控制系统在盐酸装置中的应用

Application of advanced control system in hydrochloric acid plan

以盐酸装置石墨炉为对象,设计并实施了4台盐酸炉先进控制系统,包括浓度控制、氯氢流量比控制和产量控制。该系统的投用有效提高了合成炉控制的平稳性和控制精度,取得了显著的经济效益。

The graphite furnace of hydrochloric acid plant of is taken as the object.Four advanced control systems of hydrochloric acid furnace are designed and implemented,including concentration control,flow ratio control and output control.The application of the system effectively improves the stability and accuracy of the control of the synthesis furnace,and achieves remarkable economic benefits.
