Changxing Island accelerates building of world-class green petrochemical industry base

As one of China's seven major petrochemical industry bases, the Dalian Changxing Island Economic and Technological Development Zone is committed to building a world-class green petrochemical industry base through investment promotion, innovation, and business environment enhancements.

In 2023, the Dalian Changxing Island (Xizhong Island) Petrochemical Industrial Base was listed among “China’s top 30 chemical industry parks with high-quality development” for the first time, ranking third in economic output (petrochemical output value) among national chemical parks.

The petrochemical industry output value of Changxing Island reached 235.7 billion yuan ($32.51 billion), accounting for 51.5 percent of Dalian's total petrochemical industry output value and 26 percent of Dalian's total industrial output value above designated size.

After a year of intensive construction, the first phase of the Hengli New Material Science and Technology Industrial Park, invested by Hengli Petrochemical (Dalian) New Materials Technology Co Ltd with a total investment of 50 billion yuan, has since completed test trials and entered into full production.

The park focuses on projects aimed at producing 1.6 million tons of high-performance resins, 2.6 million tons of functional polyesters, and 600,000 tons of butanediol (BDO) per year, transforming basic chemical products into high-end chemical and new material products, thereby fully establishing the value chain from petroleum to fine chemicals. Once fully operational, the first phase of the industrial park is expected to generate an annual output value of 110 billion yuan.

This year, Changxing Island has vigorously promoted supply chain optimization and industrial chain integration around leading enterprises, fostered an industrial ecosystem, developed new quality productivity, and actively introduced new sectors, such as hydrogen energy and energy storage, accelerating the development of a modern industrial system backed by a robust real economy.

Construction officially began on the Dingjide POE high-end new material project, with an investment exceeding 12 billion yuan; the Huayi lithium battery project reached trial production in just 16 months; the fine chemical engineering innovation park has introduced 36 companies; and the biopharmaceutical industrial park has been officially launched.

This year, Changxing Island has prioritized providing project service guarantees and enhancing basic infrastructure to support ongoing developments effectively. To ensure the implementation of the commercial warehousing project for the PetroChina Dalian Petrochemical Company’s relocation and upgrading, 361 households were relocated from a 2-square-kilometer area over a period of 15 days. The operation of seven enterprises in the fine chemical engineering innovation park was expedited, with road paving completed and four roads opening to traffic within 26 days. To advance the construction of Xizhong Island, the 18-kilometer Petrochemical Avenue was fully connected. To ensure the timely production of the Huayi lithium battery project, the Fengming power transmission and transformation project was powered on as scheduled.

The Dalian Changxing Island (Xizhong Island) Petrochemical Industrial Base includes the Changxing Island area and the Xizhong Island area.

The Changxing Island area, fully developed by Hengli Group with an investment of over 240 billion yuan, has achieved a production capacity of 20 million tons of refined oil, 4.5 million tons of aromatics, 11.6 million tons of purified terephthalic acid (PTA), and 1.5 million tons of ethylene. The focus is on leveraging Hengli's strengths in bulk chemical raw materials, specifically in aromatics and olefin industry chains, to continually extend and supplement the industrial chain and build a cluster for chemical new materials.

The Xizhong Island area will serve as the core hub for large-scale integrated refining and chemical production, accommodating the future relocation of the PetroChina Dalian Petrochemical Company. This area will integrate multiple industrial chains and product clusters, including the ethylene resources from Bohai Rim refineries, and will focus on handling a refining capacity of 20 million tons.

In September 2023, the Dalian Changxing Island Economic and Technological Development Zone signed a contract with Liaoning Dingjide Petrochemical Co Ltd to invest in the construction of high-end new materials projects, such as POE, with an annual output of 400,000 tons.

Additionally, the zone will extend the downstream industrial chain around the relocation and upgrading project of the PetroChina Dalian Petrochemical Company, speeding up development in the Xizhong Island area.
