Since February, Maoming Petrochemical has been continuously improving the three-dimensional monitoring system for leaks in its refinery pipelines. It identified 32 key monitoring areas along these pipelines based on the system’s performance, optimized 145 alarm parameters, and integrated the DeepSeek artificial intelligence model to upgrade the algorithms used for leak detection, thereby enhancing the timeliness and accuracy of leak warnings. On December 23, 2024, Maoming Petrochemical completed the installation of a three-dimensional monitoring system for leaks in its oil refining pipelines. This system uses optical imaging technology to conduct 3D monitoring of oil refining pipelines, effectively contributing to their stable operation and enhancing emergency response capabilities. The Safety and Environmental Protection Department, Information Center, and Refining Division of Maoming Petrochemical formed a task force. Following the concept of \"Industrial Internet + Safe Production,\" they conducted repeated technical evaluations and equipment selections. Through measures such as training AI algorithm models, conducting tests on software and hardware integration, and carrying out on-site leakage tests, they successfully installed 3 fixed and 1 mobile gas cloud imaging devices, as well as 17 AI infrared thermal imaging surveillance devices. This created a three-dimensional surveillance system for leaks in the refining pipelines, enabling 24/7 visual monitoring of these pipelines. This system integrates infrared optical visualization detection technology with AI-based leak detection models, enabling accurate localization and alerting of fluid leaks. The maximum monitoring range of the aerosol imaging technology exceeds 1,000 meters, and it boasts a rapid response time on the order of milliseconds. The monitoring range of AI infrared thermal imaging technology exceeds 1,500 meters; it is capable of converting temperature distribution images into thermal imaging videos and high-definition visible-light videos, thereby enabling 24/7 monitoring of key production equipment. Currently, Maoming Petrochemical is using on-board mobile gas cloud imaging devices to monitor the operations of three units – Unit 1 Delayed Coking, Propane, and Unit 2 Catalysis – on-site, thereby helping to ensure the stable operation of the refinery’s pipelines.
