CNOOC Refining and Chemical Daxie Petrochemical's 10-million-ton Refining and Chemical Integration Project Successfully Started

Project scale and strategic significance

on August 22, CNOOC announced that its Daxie Petrochemical Refining and Chemical Integration Project was successfully put into operation in Ningbo, Zhejiang. This event marked a major breakthrough in the technological autonomy and industrial upgrading of China's petrochemical industry. With a total investment of 21 billion yuan, the project is currently the largest new petrochemical industry base project in China. Its successful commissioning will have a profound impact on the global heavy oil processing market.

From the perspective of industrial layout, the commissioning of Daxie Petrochemical has further consolidated the status of Ningbo, Zhejiang as a world-class petrochemical industry base. For overseas chemical traders, this means that China's supply capacity in the field of heavy oil deep processing has been significantly enhanced, especially in the independent supply capacity of high-end chemical raw materials, which will directly affect the global chemical raw material trade flow and price system.

Technological Innovation and Capacity Breakthrough

core technology advantage

the biggest highlight of the Daxie petrochemical project is the use of China's independent research and development of heavy oil direct cracking chemicals complete sets of technology, the overall process localization rate of 100. This technological breakthrough has important strategic significance: first, it breaks foreign technological monopoly and reduces the risk of technological dependence of Chinese petrochemical enterprises; second, it provides new technological choices for global petrochemical enterprises, especially for countries and regions with rich heavy oil resources.

Capacity data analysis

the core unit of the project, the 3.2 million-ton/year catalytic cracking unit, has an annual output of 1.2 million tons of polymer-grade ethylene and propylene, bringing the total olefin production capacity of Daxie Petrochemical to 1.8 million tons/year, making it the largest production base for direct conversion of heavy oil to olefins in the country.

From a global market perspective, this capacity increase will have a significant impact on the balance of olefin supply and demand in the Asia-Pacific region. For overseas suppliers, it is necessary to re-evaluate their competitive strategies in the Chinese market; for downstream users, this means that the stability of raw material supply and cost competitiveness will be improved.

Environmental protection and efficiency improvement

compared with the traditional process, the new process can reduce energy consumption per unit product by more than 30% and reduce carbon dioxide emissions by 200000 tons per year. This data shows that Daxie Petrochemical not only achieved a breakthrough in the scale of production capacity, but also set a new benchmark in green development. Under the trend of global carbon neutrality, this low-carbon technology path has important demonstration significance for other petrochemical enterprises.

Engineering Technology Innovation and Construction Achievements

in the process of project construction, the technical challenges faced by the team are also worthy of attention. Aiming at the hoisting problem of super-large equipment with a diameter of 21 meters for the core equipment reactor and regenerator head, the project team pioneered the "face-up lining construction technology" and successfully solved the installation problem of 1145 tons of giant equipment.

The significance of this innovative technology is not only to solve specific engineering problems, but also to shorten the construction period by 90 days, creating the shortest hoisting period of similar equipment in China. For international petrochemical engineering contractors, this technological innovation provides a new solution and has high promotion value.

Market Impact and Prospects

the successful commissioning of the Daxie Petrochemical Project will have multiple impacts on the global chemical industry chain:

supply-side impact: The improvement of China's heavy oil processing capacity will enhance its voice in the global petrochemical industry chain, especially in the polymer-grade olefin market.

Technical end impact the successful application of independent technology will promote the international promotion of related technologies and provide technical support for the construction of petrochemical projects in countries along the "Belt and Road.

Competitive landscape impact the commissioning of the project will further intensify competition in the Asia-Pacific olefin market and prompt global suppliers to optimize their product mix and market strategies.

In the long run, the Daxie Petrochemical Project not only improves the technical level and supply capacity of China's petrochemical industry, but also provides new solutions for the technological progress and sustainable development of the global petrochemical industry. For overseas chemical practitioners, paying close attention to the development trend of Sinopec technology and actively seeking cooperation opportunities will be an important strategy for future market competition.
