According to Sinochem New Network, in 2025, the corrosion protection research team at Jinxī Petrochemical Company’s Digital and Intelligent Technology Center (Research Institute) focused on the application of core technologies for corrosion management. Through measures such as digital monitoring, process optimization, and crude oil assessment, it managed to achieve several prevention and control objectives that exceeded expectations, thereby laying a solid technical foundation for the stable operation of the production facilities. Backed by digital technologies, the research team has established a full-cycle corrosion monitoring system that analyzes offline, online, and process-related corrosion monitoring data on a weekly basis, enabling early warning of corrosion trends and precise control thereof. Addressing the key issues associated with distillation units, the anti-corrosion measures for the electrodialysis process are continuously improved, and clear guidelines for backwashing operations are established to effectively prevent abnormal levels of iron in the crude oil after treatment. Throughout the year, the integrity rate of online monitoring probes was 99.92%, with 100% coverage of all critical areas; the compliance rate for iron ions in the process anti-corrosion water medium was 98.97%, while the compliance rates for pH and chloride ions were 100%. The compliance rate for deep desalination of crude oil was 95.31%, all of which exceeded the set targets. Technical services and data support are advanced in tandem. Throughout the year, the research team prepared 11 monthly reports on corrosion protection technologies and 41 weekly reports on corrosion protection information for the research institute. They identified 56 cases of corrosion issues in various devices and proposed 26 targeted prevention measures, providing direct technical guidance for corrosion control in production processes. 10 evaluations of crude oil systems in the Liaohe, Daqing, Niger and other areas were completed, 6 reports were issued, 22 rapid crude oil evaluations were carried out along with related data maintenance. Additionally, distillation tests to determine the actual boiling points of crude oil after distillation and dehydration were conducted in both the northern and southern regions, providing data support for production operations and plant calibration. Next, the Digital and Intelligent Technology Center (Research Institute) will take the technical achievements of 2025 as a new starting point to continue focusing on research in corrosion protection technologies, enhancing its capabilities in technological leadership and scientific research support, thereby ensuring the company’s progress in technological innovation and green development in 2026.
