Company Profile
Draw on the strengths of others and do our utmost.
Changsha Boneng Technology Co., Ltd. was established on March 18, 1992, and is located in the Economic and Technological Development Zone of Langli Town, Changsha County. The company’s registered capital is RMB 109.99 million, with over 50,000 square meters of standard factory space, total assets exceeding RMB 800 million, and an annual output value of RMB 500 million. It specializes in providing tower trays, packing materials, internal tower components, and Class I, II, and III pressure vessels to major petrochemical enterprises. In 1998, the company obtained ISO 9001 international quality management system certification and holds design qualifications for Class I, II, and III pressure vessels as well as manufacturing qualifications for such vessels. It is a member of the resource market of Sinopec, PetroChina, CNOOC, China Energy, and ChemChina, and has been awarded an AA– rating by the Sinopec E-Paike Business Credit Center.
The company currently employs over 400 staff, including 36 mid- and senior-level engineering technicians, 35 certified welders, and six Level II NDT personnel qualified in radiographic testing (RT), ultrasonic testing (UT), penetrant testing (PT), and magnetic particle testing (MT). The company is equipped with more than 1,000 pieces of machinery and boasts an annual production capacity of 25,000 tonnes of tower trays, approximately 54,000 cubic meters of packing materials, and 30,000 tonnes of equipment. Thanks to nearly three decades of relentless effort and continuous innovation by the BoNeng team, our technologies have now reached a leading position domestically.
The company has established an in-house R&D team and continues to increase investment in both funding and talent development, resulting in a series of significant R&D achievements and patents (for details, please refer to the Company’s Patent Overview).
Since 2015, the company has successively commissioned three pilot-scale test facilities as follows:
1. Pilot-scale Research System for Self-Cleaning Energy-Saving Complete Equipment
2. Experimental apparatus for studying tray hydraulics data and mass-transfer hydrodynamics data of packing
3. Adjacent tower test facility.
The company boasts in-house teams for process design, equipment design, patent development, and process package development. Drawing on and integrating the advanced technological features of both domestic and international best practices, the Technical Department of Changsha Boneng has established a mature system for process simulation and equipment design. The company independently undertakes process simulation and design for large- and medium-sized tower equipment across China and has further strengthened its capabilities by engaging renowned domestic experts and professors. Leveraging state-of-the-art international simulation software and possessing robust finite-element analysis expertise, the team is able to perform strength and stress–load analyses and design optimization for critical support components such as truss beams and other internal tower internals. In addition, the company has developed proprietary hydraulics software and possesses extensive capabilities in the development of multiple process packages, including flue-gas desulfurization, methanol distillation, organosilicon production, polysilicon production, and cyclohexanone production. Furthermore, the company collaborates with numerous leading universities and research institutions nationwide—such as the School of Chemical Engineering at East China University of Science and Technology, the Institute of Process Engineering of the Chinese Academy of Sciences, China University of Petroleum, Tianjin University, Beijing University of Chemical Technology, Zhejiang University of Technology, and the Extraction Engineering Laboratory at Tsinghua University—as well as with petrochemical design institutes. Through these partnerships, the company has repeatedly delivered end-to-end services—including design, manufacturing, installation, and commissioning guidance—for new construction, capacity expansion, and technological upgrading of petrochemical facilities throughout China. As a result, the company has built substantial industry strength and accumulated rich practical experience in the design, fabrication, and quality management of large-scale towers and their internal components.

Hainan Bonengwei Heavy Intelligent Equipment Co., Ltd.
Hainan Bonengwei Heavy Intelligent Equipment Co., Ltd., established through investment, has moved into the Xiang–Hainan Joint Industrial Park for Advanced Manufacturing. Its core strategy hinges on the integrated empowerment derived from three key competitive advantages, and represents a pivotal step in implementing the company’s cross-regional development strategy:
First, by leveraging the core policy dividends of the Hainan Free Trade Port, fully benefiting from tax incentives and streamlined import–export trade procedures, operational costs can be reduced and business efficiency enhanced.
Second, leverage Hainan’s unique geographical advantages by establishing a strong local foothold to serve the Southeast Asian market while simultaneously opening up access to international markets in the Middle East, Europe, and North America, thereby expanding our global business footprint.
Third, we will integrate Hainan’s high-quality petrochemical industry resources, leveraging the industrial foundation established by leading enterprises such as Hainan Refining & Chemical and Dongfang Petrochemical, to achieve coordinated collaboration across the upstream and downstream segments of the value chain and create synergistic momentum for industrial development. Looking ahead, the company will capitalize on the policy support and locational advantages offered by the Hainan Free Trade Port in the clean energy sector to further expand its presence in wind-power equipment and nuclear-energy equipment, thereby opening up new growth areas in high-end equipment manufacturing.
Anhui Yunli New Materials Technology Co., Ltd.
Investing in Anhui Yunli New Materials leverages three key advantages—shareholder empowerment, favorable government policies, and strategic industrial positioning—to deliver both a solid foundation and robust growth potential, thereby helping shareholders optimize their industrial footprint and unlock value in niche markets.
I. The company is jointly controlled by Changsha Boneng (70%) and Hunan Bohong (30%), with the two major shareholders contributing RMB 50 million in registered capital to provide financial and technological support, thereby mitigating start-up risks. With sound governance and a highly professional team, the company has established a solid foundation for sustainable development.
II. The company is located in the Anhui (Huaibei) Coal Chemical Synthesis Materials Base and is eligible for support under Anhui’s new materials industry policies, including a 15% corporate income tax rate for high-tech enterprises and subsidies of up to 20% of R&D expenses. The company has successfully acquired 10.029 hectares of industrial land and will leverage the cluster advantages of the industrial park to integrate resources and reduce costs.
III. The company is focusing on the new materials sector, with a key emphasis on projects such as the 100,000-ton-per-year chlorine-free benzyl alcohol facility. The sector boasts broad growth prospects, the company’s capacity deployment aligns closely with market demand, and its products meet green and environmentally friendly requirements.
