Good news from Maoming Petrochemical: Both the 1.5 million tons per year No. 2 continuous reforming unit and the 2.4 million tons per year No. 2 hydrocracking unit have set new records for long-term operation! As the \"heart\" and \"kidneys\" of the refining division, these two sets of equipment have delivered outstanding performance, laying a solid foundation for Maoming Petrochemical to achieve a successful start to the year. They have also provided strong technical momentum for the group company’s \"second round of entrepreneurship\". Technology empowerment: Creating a “robust engine” for long-term operation. Long-term operation serves as the \"gold standard\" for assessing the technical capabilities and management level of refining and chemical processing plants. Maoming Petrochemical uses technological innovation as a lever to achieve a breakthrough in the operational efficiency of its facilities. Intelligent control system: Building on the “Artificial Intelligence+” initiative, two sets of equipment make full use of intelligent process control (IPC) systems to enable \"autonomous cruise\" of process parameters. By continuously monitoring key parameters such as reactor temperature and pressure, the system can automatically optimize operating strategies to keep fluctuations within 0.5%, thereby significantly reducing the risk of unplanned shutdowns. Preventive equipment maintenance: For key units such as the compressors in reforming units and the high-pressure pumps in hydrocracking units, a dual-diagnosis technique combining vibration monitoring and infrared thermal imaging is employed to detect potential failures three months in advance, resulting in a 40% reduction in the rate of equipment failures. At the same time, by optimizing the catalyst loading scheme, the catalyst’s service life has been extended by 15%, resulting in annual cost savings of over 10 million yuan per unit of equipment. Process optimization breakthrough: Unit 2’s continuous reforming unit achieved a historical best result by precisely regulating the reaction pressure (by reducing it by 0.08 MPa), which increased the aromatics yield to 76.2% ； Unit 2, equipped with the \"feedstock pretreatment + staged reaction\" technology, increases the yield of light oils by 3.5 percentage points, enabling an annual production increase of 120,000 tons of high-value diesel. Project Overcoming Challenges: Activating New Drivers for Development through “Demolishing the Old and Building the New” As a key component of Maoming Petrochemical’s refinery transformation and upgrading projects as well as the upgrades to its ethylene production facilities, the long-term operation of these two units represents not only a technical achievement but also a practical implementation of the strategy of “reducing oil production and increasing chemical products”. Plant upgrades and industrial chain coordination: Unit 2 hydrogen cracker supplies high-quality naphtha feedstock to downstream ethylene plants, enabling an increase in ethylene production capacity from 1 million tons per year to 1.64 million tons per year ； The high-purity aromatics produced by Unit 2’s continuous reforming unit serve as key raw materials for fine chemical projects (such as the 250,000-ton/year polystyrene plant), thereby helping to advance the industrial chain toward higher-value applications. Green and low-carbon transformation: The project includes simultaneous implementation of energy-saving and carbon-reduction measures; through a waste heat recovery system, the energy consumption of the facilities is reduced by 12%, resulting in an annual reduction of 86,000 tons of carbon dioxide emissions. Furthermore, the device achieves a wastewater reuse rate of 70%, earning it the title of “Sinopec Green Facility” and setting a benchmark for low-carbon transformation in the industry. Future Outlook: Driving New Industry Standards through Technological Innovation. At present, Maoming Petrochemical is accelerating the renovation of its older facilities by pursuing a strategy of \"high-end development, intelligence, and sustainability\". According to the plan, by 2028 the company will have 14 production units equipped with Sinopec’s own technology; the proportion of domestically produced equipment will exceed 98%, and the energy consumption of these ethylene production units will be reduced by another 13.3% compared to the industry benchmark levels. “Long-term operation is just the starting point; our goal is to make use of every drop of crude oil to the fullest. ”A responsible official from Maoming Petrochemical said that in the future, the company will continue to deepen the \"research and development–industry–market\" value chain, focusing on overcoming technical challenges related to special oils and biodegradable polymers. The goal is to achieve industrial application of 5 proprietary technologies by the end of the 15th Five-Year Plan period, thereby contributing more \"Maoming strength\" to the development of a world-class green petrochemical industry cluster in South China.
