May 23, 2026 marked the 13th anniversary of Sinopec Engineering (Group) Co., Ltd. (SEG, stock code: 2386.HK)’s Hong Kong IPO. Over the past 13 years, SEG has stayed committed to its vision of building a world-leading technology-driven engineering enterprise, continuously strengthening its capacity to create value through engineering services, technological innovation and capital operation, and delivering remarkable business achievements. Its total value of newly signed contracts has once again exceeded RMB 100 billion.
Below is a full breakdown of landmark heavyweight contracts recently awarded to SEG’s five core engineering subsidiaries.
SEI was restructured from the former Sinopec Engineering Incorporation, Beijing Design Institute (BDI) and Beijing Petrochemical Engineering Company (BPEC). BDI and BPEC originated from China’s first refinery and chemical design institutes founded in 1953, making SEI the top-tier design institute in the domestic refining sector.
So far this year, SEI has secured general design contracts for the National Energy Ordos Coal Liquefaction Upgrading Demonstration Project, partial engineering design contracts for the Hami Energy Integrated Innovation Base Project, plus engineering design and technical service agreements for the Shenhua Yulin Circular Economy Comprehensive Coal Utilization Project.
For Shandong Energy Group’s 800,000 tons/year coal-to-olefin project in Wucaiwan, Zhundong, SEI signed the EPC contract covering methanol-to-olefin (MTO), olefin separation, 1-butene and steam cracking units. This marks the first external commercial rollout of Sinopec’s proprietary SMTO complete technology on a domestic third-party market.
SEI now signs fewer full EPC packages, a reflection of its top-tier industry standing: as a leading technology provider, it avoids cut-throat price competition in low-margin construction markets.
As one of China’s two legacy specialized refinery design institutes, GPEC boasts profound expertise in oil refining.
Drawing on its deep technical accumulation, GPEC won and signed the EPC contract for the 1# atmospheric & vacuum distillation unit expansion and refinery central control room works of Sinopec Tahe Refining Integrated Complex. It also became the preferred bidder for the EPC tender of a 2.4 million tons/year hydrocracking complex for Shanghai Petrochemical, a mega deal worth nearly RMB 1 billion.
While consolidating its traditional refining strengths, GPEC is accelerating transformation by expanding into chemical engineering and overseas market development.
Founded in 1952, formerly known as Shanghai Pharmaceutical Design Institute, SSEC is China’s oldest professional pharmaceutical design institute and one of the earliest comprehensive survey & design firms engaged in petrochemical engineering. Its core business covers three major segments: petrochemicals & chemical fibers, pharmaceutical & bioenergy chemicals, as well as environmental protection, electronics, textile, food and natural gas storage & transportation engineering.
Recently, SSEC secured the EPC contract for a 200,000 tons/year vinyl acetate unit and a 120,000 tons/year VAE unit under the Zhongtian Hechuang Green Low-Carbon Retrofit Project.
It also won the EPC tender for the off-site carbon fiber relocation project of Shanghai Petrochemical’s 30,000 tons/year large-tow carbon fiber line, leveraging nearly two decades of joint R&D experience with Shanghai Petrochemical in carbon fiber technology and its core strengths in technical innovation and industrial conversion.
For the Shandong Energy Wucaiwan 800,000 tons/year coal-to-olefin project, SSEC was awarded the EPC contract for the whole-site tank farm system.
SNEC was formed via the merger of the former Lanzhou Design Institute and Sinopec No.3 Construction Company. It holds traditional advantages in coal chemical, acrylonitrile and polyolefin projects, covering the full industrial chain of technical R&D, consulting, design, construction, equipment manufacturing and integrated EPC project management.
Under the Zhongtian Hechuang green decarbonization upgrade project, SNEC signed EPC contracts for a 17,000 Nm³/h cryogenic separation unit, a 300,000 tons/year acetic acid unit, coal-to-methanol revamp works and auxiliary public facilities.
As the overall design institute for the National Energy Zhundong 2 BCM/year coal-to-natural gas project, SNEC was awarded two EPC tenders including overall & basic design, wastewater treatment system and full-site utility works. It will rely on mature experience in coal chemical utilities, water treatment and full-site system construction to deliver high-standard low-carbon construction and support the high-quality transition of the energy sector.
For the Shandong Energy Wucaiwan coal-to-olefin complex, SNEC secured the EPC contract for the air separation unit.
SNEI has long specialized in inorganic chemical engineering with multiple proprietary core technologies.
It was selected as the overall design institute and awarded full EPC contracts for the 50,000 tons/year high-grade flame retardant unit and whole-site auxiliary facilities of Hubei Yihua Chuxing Ecological Technology’s phosphorus & fluorine high-value utilization project.
The Sinopec Great Wall Energy & Chemical (Ningxia) CO₂ chemical looping mineralization industrial demonstration project adopts proprietary CO₂ mineralization co-developed by Sinopec and Yuanchu Technology, with a CO₂ absorption rate exceeding 90% to realize permanent carbon sequestration and resolve poor economic returns and scaling barriers of conventional mineralization technology. The project has been listed in the first batch of National Development and Reform Commission’s Advanced Green Low-Carbon Technology Demonstration Catalogue, and SNEI was awarded its full EPC contract.
In addition, SNEI signed EPC agreements for eastern district wastewater & high-salinity water treatment, storage & transportation systems and auxiliary production facilities for the Zhongtian Hechuang green decarbonization renovation project.
