Intelligent control in crude benzol recovery process

摘要

The process of crude benzene recovery analysis and design the control program of humanoid intelligent, in order to control the temperature of rich-oil, the top of benzole stripping column and the condenser. Intelligent control system consists of two-story. Top-level application expert systems identify the system status and trends real-time, and harmonize and optimize of each sub-control system of the bottom through the expert rules. The bottom constitutes a multi-loop fuzzy controller with the combination of modern control and fuzzy control: multi-loop fuzzy controller bear to achieve the temperature control of the rich-oil, the top of benzole stripping column and the condenser. The simulation results of the bottom controller show that: introducing intelligent control algorithm in the process of temperature regulation is a great performance.
