Abstract

Petroleum coke is usually calcined in rotary kiln. It is a very prevalent problem of unstable production conditions and low recovery rates in coke calcination process. The temperature field in calcining zone is a crucial factor that affects the output and quality of calcined petroleum coke (CPC). Based on the analysis of the major factors affecting the temperature field in above zone, an intelligent control system for coke calcination in rotary kiln is presented to stabilize the temperature field and maximize coke calcination rotary kiln performance by expert hybrid reasoning method combining case-based reasoning with rule-based reasoning in this paper. Some main subsystems are introduced briefly. The system has been running in a coke calcination plant since 2005. Efficiency, economy, and unusual facility and reliability of control system are improved. The results of actual running show the validity and the feasibility of this system.
