| Abstract: | On the basis of Honeywell DCS system-TDC3000,combination with multi-variable predictive control and soft measurement technique,PX oxidation reaction advanced control system and TA quality advanced control system were implemented.Under the combined control of the two system,the strong coupling and multiple constrains problems in the oxidation were well solved.Consequently,the operation conditions of the oxidation reator were stabilized and optimized,the TA product quality was increased. |
