In 2026, a vessel named Huayang departed from Tianjin Port, carrying 3,400 tons of anti-corrosion submerged arc welded steel pipes manufactured by Huayang Steel Pipe. The pipe specification is Φ508×7.1mm LSAW with 3PE coating, with a total laying length of approximately 30 kilometers, which will be applied to the construction of Kuwait’s crude oil trunk pipeline project. Oil transmission projects impose stringent requirements on steel pipe quality. Weld seam quality, anti-corrosion structure and dimensional consistency directly affect subsequent construction efficiency and long-term pipeline operational safety. Equipped with state-of-the-art anti-corrosion production lines, Huayang boasts solid advantages in process stability and quality control, fully capable of meeting the technical standards of such large-scale energy projects. Huayang Steel Pipe successfully obtained the official pre-qualification certification to enter the Kuwaiti market in 2025, signifying that its product quality, manufacturing capacity and project delivery system have passed comprehensive audits by Kuwait’s oil and gas industry authorities.

This giant steel structure, over 50 meters long, more than 20 meters wide, nearly 50 meters high and with a total weight exceeding 2,000 tons, marks a landmark achievement for Maoming Zhongli after it systematically mastered core technologies including modular design and integrated manufacturing of large-scale complete ethylene cracking furnaces for the first time. As a major national strategic refining and chemical integration project, the CNOOC Shell Huizhou Phase III Ethylene Project involves a total investment of 48 billion yuan. Upon completion, its total ethylene production capacity will reach 3.8 million t/a, making it the largest single-unit ethylene production base in China. Serving as the core "heart" of the entire facility, the 1.6 million t/a ethylene cracking furnace directly determines the operational efficiency, safety and stability of the whole plant by virtue of its technical standard and manufacturing quality.

The debottlenecking revamp and energy efficiency upgrading project for Fushun Petrochemical’s 800 kt/a ethylene plant has entered its final construction phase. Handover for commissioning is scheduled for the end of June 2026, with formal commissioning and startup by late September. Upon completion, the plant’s annual ethylene capacity will rise from 800,000 tons to 950,000 tons, with a total investment of 2.58 billion yuan. Alongside the ethylene capacity expansion from 800 kt/a to 950 kt/a, a brand-new 200 kt/a solution-process polyethylene plant will be constructed, adopting PetroChina’s first domestically developed proprietary process technology. Auxiliary supporting units including air separation, butadiene extraction and MTBE facilities will also undergo technical upgrading. The project applies a modular "building-block" construction methodology. For instance, the No.9 cracking furnace was fully pre-assembled at a prefabrication yard before being shifted into place as a whole. This construction mode enables revamping works to proceed alongside ongoing plant production without disrupting the normal operation of existing facilities. In addition, domestically manufactured million-ton-class ethylene compressors and proprietary large-scale ethylene technologies developed by China Huanqiu Contracting & Engineering Corporation are deployed for the project.

Location: Maoming, GuangdongInvestment Scale: Approximately 30.5 billion yuan Core Content:This project serves as a benchmark for Sinopec's "reduce oil production, increase chemical output" strategy. While maintaining the annual crude oil processing capacity of 18 million tons unchanged, the project will drastically reduce refined oil output by 1.85 mt/a and increase ethylene feedstock production by 1.67 mt/a instead. Four key processing units will be newly built, including a 3 mt/a Deep Catalytic Cracking (DCC) unit. The annual ethylene production capacity will be expanded from the original 1 million tons to 1.64 million tons. For downstream industries, priority will be given to constructing new production facilities including a 300kt/a propylene oxide unit, a 240kt/a hydrogen peroxide unit, and a 100kt/a POE (polyolefin elastomer) unit, filling the domestic gap in high-end polyolefins. 2026 Progress:The project is in the critical stage of completion and commissioning. Full mechanical completion is expected by the end of 2026, with some units such as the propylene oxide plant having already taken the lead in trial operation.

With a total investment of approximately 870 million euros, this is BASF's largest single overseas investment to date, as well as the largest wholly foreign-owned single project invested by a German enterprise in China. As BASF's third-largest integrated production base worldwide, the site covers about 4 square kilometers and is located in the Petrochemical Industrial Park on Donghai Island, Zhanjiang. It is independently constructed and operated by BASF. The base houses the world's first ethylene complex whose main compressors (electric-driven) are 100% powered by renewable energy. Through long-term direct green power purchase agreements and investments in offshore wind farms, it achieves 100% renewable electricity supply. Following full commencement of production, the site has successfully put 18 plants and 32 production lines into operation, enabling full-process production capacity from ethylene cracking to downstream high value-added products. The core facility of the site is a steam cracker with an annual ethylene production capacity of 1 million tons, featuring high feedstock flexibility that allows processing of various feedstocks including naphtha and butane.

China's first full-chain domestic 100kt/a solution-processed polyolefin elastomer (POE) industrial plant has entered a critical commissioning phase at Tianjin Petrochemical Corporation. This technology has achieved a comprehensive domestic upgrade and improvement of the entire value chain, including catalysts, process technology, plant equipment, and automatic control systems. Meanwhile, Sinopec is accelerating the construction of its 100kt/a POE plant in Zhenhai Refining & Chemical Company, and the domestic solution-processed POE production technology has entered a phase of full-scale capacity expansion. The localization rate of equipment for the POE plant at Tianjin Petrochemical, which has now entered the commissioning phase, has been raised to 99%. This has promoted the improvement of the localization level of key equipment for high-performance synthetic materials and realized the full independent and controllable development of POE technology. In the future, with the commissioning of the POE plants at Tianjin Petrochemical and Zhenhai Refining & Chemical Company, Sinopec will have a POE production capacity of 250kt/a, helping to significantly reduce China's import dependence on POE.
