Shenghong Refining & Chemical (Lianyungang) Co., Ltd. is located at No. 59 Petrochemical 3rd Road, Xuwei New Area, Lianyungang City, covering an area of 500 hectares. As a key project supported by the national "Petrochemical Industry Planning and Layout Scheme," this integrated refining and chemical project serves as the core feedstock platform for Shenghong’s "1+N" strategy—creating diversified industrial chains spanning new energy, new materials, electronic chemicals, and environmental protection. It is also a pivotal project for integrating the entire industrial chain and establishing a world-class industrial cluster for new energy and new materials.
The facility features an annual processing capacity of 16 million tons of crude oil, 2.8 million tons of paraxylene (PX), and 1.1 million tons of ethylene (along with downstream derivatives). Supporting infrastructure includes a 300,000-ton crude oil terminal, four 50,000-ton liquid chemical terminals, and a tank farm with a storage capacity of 3.83 million cubic meters. Built upon the concepts of "maximizing chemicals while minimizing fuels" and "molecular refining," the project achieves a chemical product yield of 69%—the highest in China. Shenghong Refining & Chemical utilizes world-leading process technologies and equipment, with several core units setting domestic records for scale. Notably, it operates the country's largest single-train atmospheric and vacuum distillation unit (16 million tons/year) and vacuum gas oil (VGO) hydrocracking unit. The paraxylene unit marks the first domestic adoption of a two-stage heavy-residue recycling process and stands as the world's largest crystallization-based paraxylene unit. Additionally, the facility houses a leading-scale continuous reforming complex (3 × 3.1 million tons/year) that features fully localized key technologies.
The full-scale operation of Shenghong Refining & Chemical boosts the domestic supply of high-value, high-demand chemical products such as olefins and aromatics, providing a rich "chemical feedstock reservoir" to extend the industrial chain into new energy materials. With over 80% of feedstocks and products exchanged internally within the base, the project creates a complete, closed-loop high-end industrial chain. This helps reduce the Chinese petrochemical industry's reliance on international markets and accelerates the formation of a "dual circulation" pattern—integrating domestic and international markets—within the petrochemical sector.
