China's petrochemical industry safe production of intelligent guarantee technology has achieved new results

[China Instrument Network Instrument Research and Development] The petrochemical industry is an important pillar of China's national economy. For a long time, major safety issues have occurred continuously around its production, can we achieve accurate production safety early warning, avoid or reduce accidents, and effectively carry out emergency command coordination The prompt handling of accidents is a bottleneck for China's safety production and emergency management.

Recently, the project of “Risk Intelligent Identification and Security Emergency Technology and System Based on IoT Industrial Control System” in the advanced manufacturing technology of the 863 Program passed the technical acceptance of the expert group.

Under the support of the National 863 Program, CNOOC Information Technology Co., Ltd. and Zhejiang University worked together to study the modeling theory and methods of the integrated security emergency model library, and proposed a multi-level plant security model construction technology, which will be based on OPC (Object linking). And embedding for Process Control, the object connection and embedding for process control) technology integrates real-time data and data based on the Internet of Things inspection data, enabling dynamic monitoring of production processes, dynamic risk assessment and early warning, and emergency command decision-making and scheduling. The software for risk intelligent identification and safety emergency response system was developed and verified by a demonstration application at the CNOOC Refining & Chemical Co., Ltd. Huizhou Refinery Branch. A total of 2028 hazardous source objects were covered on the application site, and the risk warning time reached 37 seconds.

This achievement has provided intelligent technical guarantee means for the safety production of the petrochemical industry, and has improved the level of process industry management. At the same time, it can provide technical support for intelligent technology R&D and demonstration applications in the petrochemical industry, improve the level of enterprise automation, and avoid the risk of security accidents. It has significant guiding significance for production optimization, reduction of energy consumption and risk reduction in related industries, and has broad application prospects.
