The 11th China Industrial Gas Summit 2025 was held in Xi’an. As one of the co-organizers of the event, Shaanxi Qinfeng Industrial Gas Co., Ltd. (ShaanGu Qinfeng for short) drew significant attention from the industry.
Throughout its development, ShaanGu Qinfeng has consistently adhered to the gas supply philosophy of “Safety, Stability, Long-Term Operation, Full Load Capacity, High Quality, and Low Consumption”. The company has established a long-term mechanism for safety, environmental protection, quality, and energy management, and has obtained certifications in occupational health and safety, environmental management, energy management, and quality management systems. This solid foundation enables the safe, green, energy-efficient, low-carbon, and low-consumption operation of its gas plants. In its continuous transformation and high-quality development practices, ShaanGu Qinfeng relies on technological innovation and quality services to fully align with market demands. Its brand influence continues to expand, and it has grown into a large-scale state-owned professional industrial gas solution provider. The company’s operations span Shaanxi, Jiangsu, Anhui, Fujian, Hebei, Shandong, Shanxi, Henan, Inner Mongolia, Xinjiang, Liaoning, and other provinces, with a total industrial gas capacity of over 2 million Nm³/h. With more than 20 subsidiaries across China, it serves a wide range of industries, including steel metallurgy, petrochemicals, machinery manufacturing, and photovoltaic manufacturing.
The compressor unit for air separation plants is critical equipment, ensuring the supply of “industrial blood.” In the field of air separation, ShaanGu has independently developed a full range of 100% domestically-produced compressor units for air separation applications, covering multiple series. Their compressor solutions serve the entire spectrum and full process of air separation plants, supporting oxygen production units with capacities ranging from 10,000 to 150,000 Nm³/h. ShaanGu’s compressor units can be arranged in a single-layer layout and are characterized by high efficiency and energy savings. The mechanical and aerodynamic performance of these units has reached domestically leading and internationally advanced levels, capturing over 82% of the domestic air separation market.
The compressor unit innovatively developed by ShaanGu for 100,000 Nm³/h large air separation plants is designed with a high-pressure ratio, high-reliability, and high-efficiency 3H blade profile, which endows the compressor with notable features, including fewer stages, a compact structure, high reliability, and superior operational efficiency.
On the path of focusing on its core business and deepening the transformation toward service-oriented manufacturing, ShaanGu continues to pursue innovation. As its high-efficiency compressor units for air separation plants see expanding application in fields such as coal chemical, petrochemical, and new energy materials, ShaanGu will further intensify its efforts in technological innovation and business model innovation. The company aims to promote the broader adoption of high-efficiency ASP compressor units and integrated system solutions across these sectors. Together with upstream and downstream partners, we are committed to exploring a high-quality, green, and low-carbon development path for the industrial gas industry.
