en.Wedoany.com Reported - On July 21, 2026, Shengu Group held a technical achievement appraisal meeting and industry promotion conference for its "Ultra-large Air Separation Unit Compressor Unit" at the site of Baofeng Energy's coal-to-olefins project in Ordos, Inner Mongolia, which is the world's largest single-site project of its kind. The unit passed the appraisal jointly organized by the China Machinery Industry Federation (CMIF) and the China General Machinery Industry Association (CGMIA) in the morning, followed by a focused industry promotion in the afternoon.
The appraisal meeting was co-chaired by CMIF and CGMIA. The appraisal committee consisted of 11 experts, with Guo Dongming, an academician of the Chinese Academy of Engineering, serving as the chairman. Members came from Xi'an Jiaotong University, Northeastern University, Sinopec, PetroChina, China Energy Investment Corporation, Liupanshan Laboratory, Hangyang Group, Yitai Chemical, China Huanqiu Contracting & Engineering Corporation, and other organizations. The committee reviewed Shengu Group's technical development summary report and Baofeng Energy's unit operation report, forming an appraisal opinion stating that the unit involves significant technical difficulty and strong innovation, possesses independent intellectual property rights, fills a domestic gap in China, and achieves an overall technical level comparable to advanced international products of the same type, with aerodynamic and mechanical performance ranking internationally leading.
Dai Jishuang, Secretary of the Party Committee, Chairman, and CEO of Shengu Group, stated in his address that choosing to hold the appraisal meeting at the Baofeng site was because this project witnessed China's leap in modern coal chemical industry core equipment from heavy reliance on imports to comprehensive domestic substitution. The 115,000-grade air separation compressor unit supplied by Shengu is the core equipment supporting this leap. Gao Jianjun, Executive Vice President of Baofeng Energy and Chairman of Inner Mongolia Baofeng Coal-based New Materials Co., Ltd., shared the cooperation history between Baofeng and Shengu, stating that Shengu's units laid a solid foundation for the full-load, safe, and stable operation of Baofeng's Inner Mongolia project for over 14,400 hours.
At the afternoon promotion conference, Zhang Yong, Chief Engineer of Shengu Group, delivered a keynote report titled "Focusing on Key Equipment Breakthroughs to Empower Air Separation Industry Upgrades," reviewing over 20 years of technological evolution in large air separation compressors. Huang Li, President of CGMIA, announced the appraisal results at the promotion conference and stated that orderly development of coal deep processing is an important energy strategy for China, and Shengu has demonstrated its capability to undertake national major equipment localization during the development of large air separation compressors.
This ultra-large air separation unit compressor set is primarily applied to the methanol project of the Inner Mongolia Baofeng green hydrogen and coal chemical coupling carbon reduction innovation demonstration project. Six units form the largest fully domestically produced air separation cluster in China. The overall unit is divided into an air compressor, a booster compressor, drive equipment, and auxiliary systems. The air compressor adopts the SACC "6+1" axial-plus-centrifugal structure, consisting of 6 axial flow stages and 1 centrifugal impeller; the booster compressor adopts the SVK63-6H assembled structure, containing 6 impeller stages and 4 interstage coolings. Since entering commercial operation, the unit has maintained continuous and uninterrupted operation, with actual energy consumption lower than the design value, and vibration and temperature rise indicators remaining stable in the excellent range for a long time. It is well-adapted to the Hangyang air separation system, and the entire set of equipment maintains a stable oxygen production capacity at the rated load of 110,000 Nm³/h.
This appraisal and promotion event marks that Shengu Group has achieved a full-chain closure from technological breakthrough to industrial application and industry recognition in the field of ultra-large air separation unit compressor sets, signifying that China has formed an independent technical system and industrialization capability in the field of ultra-large air separation core equipment.
