Recently, the Jinxi Petrochemical Project Department of Kunlun Engineering’s Dalian branch successfully completed the work related to the heating furnaces in the hydrocracking unit as part of the project to improve the efficiency of those heating furnaces. The goal of carrying out a comprehensive maintenance of the unit was achieved, and new graphene preheaters were put into use. To ensure the project is delivered on schedule, the project team has always worked hard at the front line with a determination to go all out and a commitment to excellence. Whether it is a late night with stars low in the sky or a holiday spent together as a family, the construction sites keep humming like in daylight; sparks fly like stars, and the red lights from measuring instruments along with the fluorescence of safety helmets shine in the darkness, combining to form a symphony of determination as people strive to overcome challenges. This project utilizes a graphene-composite tubular air preheater designed by the Mechanical Equipment Design Department of the Dalian branch. As the first application of this type of equipment within CNPC, it boasts excellent heat exchange performance thanks to the extremely high thermal conductivity of graphene material. The innovative composite structure design simultaneously enhances resistance to sulfur corrosion, ensuring excellent durability even under the high-temperature flue gas conditions in refining facilities. Compared to traditional plate-type or heat-tube preheaters, this device features a breakthrough tubular structure design combined with an innovative modular layout, which improves air flow and effectively reduces ash accumulation and blockages, thereby extending the equipment’s maintenance cycle compared to similar products. Through the innovative integration of materials science and intelligent technologies, the Jinxī Petrochemical 95+ project achieves a significant improvement in the thermal efficiency of its heating furnaces, and it continuously optimizes equipment performance and operational economics by relying on a full-process closed-loop management system. The project innovatively established a systematic approach for the large-scale industrial application of graphene materials, as well as a digital design framework that takes all relevant factors into account, thereby providing a solid technical foundation for Jinxi Petrochemical to become a benchmark enterprise in terms of green and low-carbon practices. Looking to the future, Kunlun Dalian Branch will always adhere to a development strategy driven by innovation, boldly explore uncharted technological territories, strive to achieve new heights in manufacturing techniques, and forge ahead through challenges on the path to building strong technological capabilities, thereby drawing up a grand blueprint for setting new benchmarks in the industry.
