Shenghong Refining & Chemical (Lianyungang) Co., Ltd. was founded on July 23, 2014 in Xuwei New Area, Lianyungang, Jiangsu Province, with a registered capital of RMB 23.545 billion. As a private manufacturing enterprise and the operator of the national key integrated refining‑chemical project specified in China’s Petrochemical Industry Planning & Layout Scheme, it acts as the flagship entity of Shenghong Holding Group within Lianyungang Petrochemical Industrial Base.Built upon Shenghong Petrochemical Industrial Park, the company implements the “1+N” industrial framework. It coordinates crude‑oil refining with high‑end chemical production, achieving a chemical output ratio of nearly 70%. More than 80% of raw materials and products are supplied and consumed mutually inside the park. The industrial chain is further extended through supporting projects including Honggang Petrochemical’s PTA production and Sierbang Petrochemical, forming a complete value chain ranging from crude oil processing to advanced new‑material manufacturing. Committed to reinforcing domestic supply of scarce petrochemicals, the enterprise effectively lowers China’s reliance on imported chemical products and strengthens industrial‑chain security.Driven by technological innovation, the company holds 101 authorized patents. Its self‑developed “Hongyun” industrial internet platform has been listed among the World’s Top 10 Industrial Internet Application Cases. Advocating green and low‑carbon operation, it reaches 85% reutilization rate of reclaimed water, with ethylene energy consumption hitting benchmark level of the sector, together with comprehensive recycling of three types of industrial waste. In 2024, the world’s first negative‑carbon industrial chain of “CO₂‑green methanol‑new energy & new materials” was put into operation. Based on high‑concentration CO₂ emitted from No.2 ethylene glycol unit, the 250 kt/a CO₂ recovery & purification facility produces 220 kt/a food‑grade liquid CO₂ and 30 kt/a food‑grade dry ice, delivering an annual CO₂ emission reduction of around 212 kt.For outstanding operational and environmental performance, the company was awarded the honor of “Advanced Collective of National Industry and Information Technology System” and included in the national green manufacturing list as a National‑Level Green Factory in 2025. The Shenghong Petrochemical Industrial Park operated by the company serves as one pillar brand of China’s seven world‑class petrochemical bases. Looking ahead, the enterprise will advance towards high‑end, digital‑intelligent and low‑carbon transformation, striving to build a world‑class R&D and manufacturing base for new‑energy and new‑material products。 Contact Person:Fanki ShiMobile:+8615651039172WhatsApp/WeChat:+8615651039172E-mail:sales9@boxa-chem.com
Jiangsu Eastern Shenghong Co., Ltd Announcement of full-scale commercial operation of Shenghong Refining and Chemical (Lianyungang) Co., Ltd.'s 16 million tons integrated refinery-petrochemical production complex. The Company and all members of the Board of Directors warrant that the content of the information disclosure is true, accurate and complete, and there are no false records, misleading statements or material omissions. Shenghong Refining and Chemical (Lianyungang) Co., Ltd., a secondary-owned wholly-owned subsidiary of Jiangsu Eastern Shenghong Co., Ltd. (hereinafter referred to as "the Company"), invested in the construction of atmospheric and vacuum distillation plant of the “Shenghong Refining and Chemical (Lianyungang) Co., Ltd. 16 million tons integrated refinery-petrochemical production complex project” (hereinafter referred to as the “Shenghong Project”) in Lianyungang Petrochemical Industrial Base, which was successfully put into operation in May 2022. Please find more details on the announcement of the commissioning of Shenghong Refining and Chemical (Lianyungang) Co., Ltd.'s 16 million tons of integrated refinery-petrochemical production complex project (Announcement No. 2022-079). Up to now, Shenghong Project’s oil refining, aromatics, ethylene, and downstream chemical products units have been fully put into testing and running, started full-scale commercial operation, and have achieved stable operation and produced corresponding qualified products. The Company will further improve the relevant process parameters, and enhance the production operating level. Shenghong Project adopts the world's leading green production process technology, and has China's largest single set of 16 million tons of atmospheric and vacuum distillation unit, the world's largest 2.8 million tons/year two-stage heavy slurry crystallization process paraxylene plant, the largest 4 million tons/year wax oil hydrocracking unit in China, the 3*3.1 million tons/year continuous reformer, and other large-scale refining and chemical units. The full-scaleproduction of Shenghong Project will provide large-scale, low-cost and abundant raw materials for the Company's downstream production of renewable energy materials and performancechemicals, further consolidate the Company's competitive advantages, help the Company to strategically expand into renewable energy materials industry and realize the corporate vision to enable a green and sustainable future with innovative chemistry and new materials.

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.
Dedicated to excellence in chemistry — serving industries worldwide with integrity and innovation.
