Entity

Hengli Petrochemical (Dalian) Refining Co., Ltd. (恒力石化（大连）炼化有限公司) is the Hengli Group operating platform for the large integrated refining and petrochemical complex on Changxing Island, Dalian, Liaoning Province, China. The company develops and operates the 20 million t/y crude‑to‑chemicals refinery and the core associated petrochemical value chains within the Hengli (Dalian Changxing Island) Industrial Park, and supplies transportation fuels, petrochemical feedstocks and key intermediates to other Hengli entities at the site.

Corporate identity and ownership

Hengli Petrochemical (Dalian) Refining Co., Ltd. is a wholly owned subsidiary of Hengli Petrochemical Co., Ltd., which itself is a core subsidiary of privately held Hengli Group, a Fortune Global 500 conglomerate active in oil refining, petrochemicals, advanced polyester materials and textiles. Within this structure, Hengli Petrochemical (Dalian) Refining Co., Ltd. acts as the project‑level operator and asset‑holding company for the 20 million t/y crude‑to‑chemicals project, integrating crude oil processing, heavy‑oil conversion and key upstream petrochemical units that supply downstream PTA and new‑materials plants in the industrial park.

Business activities and product portfolio

The company’s core business is the operation of a world‑scale refining and petrochemical complex with an oil refining scale of 20 million t/y and up to 31 major refining units, producing a slate of transportation fuels, petrochemical feedstocks and chemical intermediates. Key outputs from the refinery and petrochemical units include gasoline, diesel and jet fuel; LPG; lube base oils; paraxylene and other xylenes; benzene; chemical light oils; sulfur; and a range of aromatics‑ and olefins‑based intermediates that feed into downstream PTA, ethylene glycol and polymer units at the industrial park. Deep conversion technologies and integrated aromatics units are configured to maximize naphtha and PX‑rich streams for the Hengli polyester chain while minimizing low‑value fuel oil.

Through the broader Hengli Petrochemical platform, Hengli Petrochemical (Dalian) Refining Co., Ltd. is integrated into a value chain that also encompasses PTA, polyester chips and fibers, films and new materials such as engineering plastics and biodegradable materials, allowing refinery‑derived hydrocarbons and aromatics to be upgraded into polyester and specialty polymer products. In practice, this makes the refining entity both a fuels supplier and the primary internal supplier of feedstocks (e.g. PX and other aromatics, LPG/propylene streams) to Hengli’s PTA and polyester operations on Changxing Island and beyond.

Location and infrastructure

Hengli Petrochemical (Dalian) Refining Co., Ltd. is based in the Changxing Island Economic and Technological Development Zone on the Bohai Sea. The Changxing Island location provides deep‑water port access for crude imports and product exports, and hosts extensive storage, utilities, gasification, hydrogen and environmental infrastructure sized to support 20 million t/y of crude throughput. The refining‑chemical project is described as discharging refinery wastewater of about 36,000 t/d and supporting a PTA project of 6.6 Mt/y in the same industrial park, underlining the scale of onsite processing and environmental systems.

Role within Hengli Group

Within Hengli Group’s integrated model, Hengli Petrochemical (Dalian) Refining Co., Ltd. is a central upstream and midstream asset that underpins the group’s move from a textile‑based origin to a fully integrated oil refining and petrochemical player. The commissioning of the Dalian refinery and petrochemical complex in 2019, with a crude capacity of about 400,000 b/d, marked a significant inflection point in Hengli’s growth, giving the group control over its own crude sourcing and aromatics/PTA feedstocks and elevating its position in global petrochemical and polyester value chains.
