针对复杂多变的石化装置生产过程,提出了过程安全管控架构和技术路线,给出了基于异常工况识别预警的实时安全运行指导系统和过程安全管理评估系统,并在某炼化企业的延迟焦化、催化裂化、乙烯等装置开展了应用.结果表明,该系统可增强装置异常工况监测预警和处置能力,对保障装置安全稳定运行,提升装置风险智能化管控水平具有现实意义.%Aiming at the complex and variable petrochemical plant production process,in order to realize the dynamic monitoring,analysis,early warning and control of the risk of production process,and to improve the handling capability of the abnormal event and process safety management level of the production plant,this paper proposed process safety management and control architecture and technology route of real-time and periodic combination. It proposed the real-timesafety operation guidance system and the process safety management assessment system based on the abnormal condition identification and early warning technology. It is applied to the delayed coking,catalytic cracking and ethylene plant of petrochemical enterprise. Application showed that the system can enhance the abnormal operating condition monitoring and early warning and disposal capability. It has practical significance for ensuring the safe and stabile operation and upgrading risk's intelligent control level of these units and plants.
