Oxygen is produced from the largest air separation island in China
Recently, the first set of six 110,000 standard cubic meters per hour air separation units provided by Hangzhou Oxygen Group Co., Ltd. for the Inner Mongolia coal-to-olefins demonstration project of Baofeng Energy successfully produced oxygen, marking a new step forward for domestic super-large air separation equipment.
It is understood that this project is currently the largest single-plant coal-to-olefins project in the world. The six sets of 110,000-cubic-meter air separation units to be built in the project are currently the largest and highest-grade air separation islands in China in terms of one-time construction scale, which will provide a strong gas supply for the operation of the project. This is also the largest order for super-large air separation equipment that Hangzhou Oxygen has ever received in terms of both the number of sets and the scale grade.

Han Yisong, deputy secretary of the Party Committee and general manager of Hangzhou Oxygen Group Co., LTD., introduced that the 110,000-grade air separation equipment for this project adopts core and key components such as high-pressure aluminum plate-fin heat exchangers and large-diameter molecular sieve switching three-stem valves independently developed by Hangzhou Oxygen. It features short design, manufacturing and construction periods, high domestic production rate and high domestic production level. This project is equipped with an argon-air separation unit and a krypton-depleted xenon liquid extraction device. Its unique process design and on-site assembly technology are both at the leading level internationally. In addition, Hangzhou Oxygen has deeply integrated air separation equipment with digitalization. Through real-time monitoring and process traceability in the intelligent operation center, it ensures the stable operation, energy conservation and environmental protection of the equipment, leading the domestic air separation industry towards high-end, refined and intelligent development.
Zheng Wei, the Party Secretary and Chairman of Hangzhou Oxygen Group Co., LTD., stated: The Baofeng Energy project is the "No. 1 project" that Hangzhou Oxygen has been undertaking in the air separation projects in the past two years. It is characterized by a tight schedule, high grade, large scale and heavy responsibility. We overcame numerous difficulties such as the unsmooth foreign supply chain and the development of high and low pressure integrated plate heat exchangers, and successfully delivered the project, setting a record for the shortest manufacturing cycle, the highest domestic production rate and domestic production level among air separation projects of the same grade and scale. The smooth progress and successful start-up of the project are of great significance for consolidating the foundation of Hangzhou Oxygen's equipment industry and further enhancing the luster of Hangzhou Oxygen's "golden business card" of super-large air separation. We will always adhere to independent innovation, continuously promote technological progress, and provide the world with green equipment, gas products and services that can create sustainable value. We will repay our customers and society with better products, services and cost performance.
Gao Jianjun, executive vice president of Ningxia Baofeng Energy Group Co., Ltd. and chairman of Inner Mongolia Baofeng Coal-based New Materials Co., LTD., pointed out that based on the perfect integration of technology and resources and the deep resonance of enterprise concepts and visions, Hangzhou Oxygen and Baofeng Energy have jointly set a new record for the construction speed of the largest air separation unit in China.
It is reported that in order to address issues such as large air separation grades and high transportation difficulties, Hangzhou Oxygen Co., Ltd. considered design, production and installation in a coordinated manner at the early stage of the project. It creatively applied technologies such as on-site assembly and welding of large-diameter upper and lower tower sections, and optimized the design and installation plans in response to the frequent sandy and dusty weather in the northern part of the country. The main tower assembly of six sets of air separation units was successfully connected on site and the cold box was topped out on schedule, which was highly recognized by the owner.
Air separation equipment is the "ventilator" of the national industry. We must firmly hold the core technologies and the initiative of the supply chain in our own hands and strengthen the industrial support. A responsible person from Hangzhou Oxygen Group stated that in the future, Hangzhou Oxygen will continuously expand the depth of its industrial chain, extend the air separation industrial chain to the gas supply service field, strengthen research in hydrogen energy equipment, helium, bulk electronic gases and other areas, develop towards high-tech and high-value-added products, and provide customers with efficient, energy-saving and stable customized high-quality gas supply service solutions.
The ascent of grade scale, the iteration of technology and processes, the breakthrough of key components and machines, as well as the technological progress and innovation of achievements of major domestic equipment, is a long-term process of climbing uphill. Based on its 74 years of technological accumulation in the field of deep cryogenic and gas separation, Hangzhou Oxygen will refine its products and solidify its processes. It will continue to maintain a high frequency of new product launches and enhance the quality of new products, leading the technological development of China's air separation industry." Han Yisong said.
