Since it was completed and put into production in 1965, Kaifeng Air Subsidiary has provided domestic and international users with more than 500 sets of air separation equipment of various specifications and models, among which nearly 40 sets have been exported to Southeast Asia, the Middle East, West Asia, and the European Union. For more than 40 years, especially since the 1990s, the Kaifeng Air Subsidiary Group has made unremitting efforts in improving technological development capabilities, researching and developing new technologies and new products, and improving the technical level of China's air separation equipment manufacturing industry. Achievements, especially in promoting the localization of China's large-scale air separation plants, have done a lot of fruitful work. By taking charge of the national research projects on the “15†large-scale air separation and localization of seven issues, Kaifeng Air Subsidiary successfully designed and manufactured a large-scale 40000m3/h auxiliary facility for 300,000 tons/year of synthetic ammonia for Shandong Hualu Hengsheng Chemical Industry Co., Ltd. The air separation project has realized the localization of the first set of large-scale air separation equipment in China's 40,000-level high-pressure in-line compression process, and has set an important milestone in the history of the development of air separation equipment in China.
The first large-scale air separation domestication project won the bid
For a long time, large-scale air separation plants with a class of more than 30,000 have been monopolized by a few foreign companies. The localization of large-scale air separation equipment has always been a goal that China's major equipment manufacturing industry hopes to realize at an early date. In order to achieve this goal, Kaifeng Air Subsidiary Group and its siblings in the same industry have done a lot of technical accumulation work, prepared and created conditions, and hope to achieve this dream by relying on projects. From the late 1990s, Kaifeng Air Subsidiary Group actively contacted Hua Lu Hengsheng (at that time, the Texas Chemical Fertilizer Plant) and supported each other. They actively applied to the former State Economic and Trade Commission and the National Machinery Industry Bureau for applying large nitrogen fertilizers and large-scale air separation. Localization projects and government support. After many arguments by experts, the project was approved by the state. In the final fierce bidding competition, Kaifeng Air Subsidiary won the bid with the advantages of reasonable and perfect technical solutions, advanced technical indicators, and remarkable technical performance. At the end of September 2002, it signed a supply contract with users and began 40,000 air separation. Localized development work.
In this major technology and equipment localization research project, the country has set up eight research projects. Kaifeng Air Subsidiary Co., Ltd. alone or together with Hualu Hengsheng Co., Ltd. jointly undertakes the tasks of seven key research topics other than air compressors. September 19th, 2004 was a day of pride for the openers. On this day, the 40,000 air separation unit was successfully driven by Shandong Hualu Hengsheng. After nearly two years of operation, it has been proved that this set of equipment is of reasonable design, advanced technology, and stable and reliable operation. In mid-March this year, the test data conducted by users once again showed that the output and purity of each product basically meet the requirements of design specifications.
Experts believe that China's first 40,000-scale large-scale air separation plant has been successfully put into operation and stable and reliable operation, indicating that China has thus ranked among the world’s largest air separation technology powerhouses.

Kaifeng Air Separation Group Co., Ltd. is one of the key enterprises in China that specially design and manufacture large and medium-sized air separation equipment. The company is directly subordinated to the former Ministry of Machinery Industry. Its predecessor was Kaifeng Air Separation Equipment Factory. In 1997, it was restructured into a wholly state-owned enterprise. In order to better establish a modern enterprise system, improve the corporate governance mechanism, and promote the rapid and healthy development of enterprises, at the end of 2004 under the care and support of the Kaifeng municipal party committee and the municipal government, the company completed the complete withdrawal of state-owned assets and completely restructured it into a private enterprise.
