Abstract: In view of the existing problem of the former control system of the Yangzhi Petrochemicals butadiene distillation column, voluminous plant operation data collected by DCS and simulated results from a theoretical model are pooled together and used to build the adaptive soft-sensor instrument for butadiene and alkynes contents in the distillation column top based on the BP neural network technique. Then, an inferential control system was designed according to the targets of product quality, in which the on-line estimating values of soft sensor instrument were used. As a result of increasing logic calculation in the inferential control arithmetic, the robustness of the control system is strengthened. Application of the control system to the column showed that the control system can run smoothly over a long period in worksites, and has realized the close-loop control of product quality.
