Abstract

An expert system has been developed for monitoring the abnormal process and avoiding the dangers of purifying units in ammonia plant in this work. The regular knowledge expression method of ldquorule frame + rule bodyrdquo is used to building the knowledge base. It uses hybrid strategy for inference engine. The system is stable and reliable when put into operation, and it can monitor the abnormal process real-time, keep away the dangers of purifying units in ammonia plant, and realize fault-tolerant control under certain operation state.
