More good news in the effort to localize refining technologies: Kangjisen has achieved two breakthroughs in Fushun Petrochemical – the localized implementation of CCS+DCS systems for three units handling 1.7 million tons of heavy oil in catalytic cracking, as well as the completion of the DCS upgrade for the storage facilities at the acrylic fiber plant. These achievements represent further progress by Kangjisen in the use of domestic DCS systems in PetroChina’s refining operations. This project utilizes fully autonomous technologies to help enterprises reduce costs and carbon emissions, providing PetroChina with a practical model while also offering the industry a replicable approach to achieving equipment autonomy and control.

As the cradle of China’s grain and oil industry, Fushun Petrochemical has developed over 96 years and is now a giant integrated enterprise covering areas such as oils, chemicals, fibers, plastics, detergents, and waxes. It boasts processing capacities in the tens of millions of tons, a product portfolio of over 300 different grades, and it even provided key petrochemical materials for the launch of China’s first artificial satellite as well as for the first polar exploration missions. Yet even such an industry leader faces the practical challenges of upgrading old equipment and improving its efficiency, and Kangjisen has provided a solution for its path to renewal.

The \"three-unit system\" of Fushun Petrochemical’s heavy oil catalytic cracking unit can be regarded as the \"power hub\" for the operation of this facility – the main fan unit is composed of a flue gas turbine from Lanlian Machinery Factory, an enriched gas compressor from Shengli Heavy Industry Group, and electric motors from Shanghai Electric; along with a backup fan provided by Shengli Heavy Industry Group, this constitutes the \"heartbeat power source\" for the catalytic cracking reaction. However, as the operating years increase, the issues related to upgrading the existing control systems become increasingly prominent: • Energy consumption is a significant problem: there is a continuous need to improve energy efficiency, and there is room for optimization in terms of matching the current operating parameters of the units with their actual load; thus, there is great potential for saving energy and reducing consumption ； • Safety control risks: The original surge curve of the air compressor lacks precision, making it difficult to avoid surge risks under traditional control methods. Additionally, the decentralized control system increases the complexity of operation and maintenance.
In the renovation of the units at the Second Petrochemical Plant of China National Petroleum Fushun Petrochemical Company, the traditional decentralized control approach using multiple systems was abandoned in favor of the TSXPLUS system developed by Kangjisen, which enables \"integrated control\" – the control and interlocking of the main fans, as well as those of the backup fans, are handled by separate TSXPLUS systems. At the software level, Kangjisen’s own upper-level and lower-level computers along with specialized unit control packages are used; through the reconstruction of surge curves and the combination of performance control and decoupling control, a unified control logic is achieved, seamless data exchange is possible, and operational efficiency is significantly improved.
• CNPC’s \"model example\": As a long-standing benchmark enterprise within CNPC, the successful domestication of CCS technology for the large-scale units at Fushun Petrochemical provides a \"replicable and scalable\" template for the upgrading of similar units across CNPC’s network, thus accelerating the implementation of the strategy to localize control systems；
