总投资210亿元！我国规模最大世界级石化基地全面建成

Core Insights - China National Offshore Oil Corporation (CNOOC) announced the successful commissioning of the Dasha Petrochemical Integration Project in Ningbo, Zhejiang, marking the completion of the largest world-class petrochemical industrial base in China, enhancing the country's capability for efficient heavy oil conversion and self-sufficiency in high-end chemical materials [1][2] Investment and Production Capacity - The total investment for the project is 21 billion yuan, making it the largest newly constructed petrochemical industrial base in China. The core production unit utilizes domestically developed technology for direct cracking of heavy oil into chemical products, achieving a 100% domestic production rate [2][3] - The project features a catalytic cracking unit with an annual capacity of 3.2 million tons, producing 1.2 million tons of polymer-grade ethylene and propylene, which are essential raw materials for everyday products such as mineral water bottles and food packaging [2][3] Environmental Impact and Efficiency - The new production process reduces energy consumption per unit product by over 30% compared to traditional methods, leading to a reduction of 200,000 tons of carbon dioxide emissions annually, significantly improving the efficiency of heavy oil resource utilization [2][3] - The project contributes to the low-carbon transition of refining enterprises and has profound implications for optimizing China's petrochemical raw material structure and reducing carbon emissions from single-unit olefin products [2][3] Technological Innovation - The construction faced challenges due to the unique design of the core equipment, which required innovative "upside-down lining construction technology" to install a giant steel bowl weighing 1,145 tons at a height of 25 meters, shortening the construction period by 90 days [4] - The project sets a new benchmark for the construction of large-scale petrochemical equipment in China, enhancing the country's capabilities in core chemical processes and equipment manufacturing [4]
