Qiyuan has nearly 20 years of R&D and manufacturing capability of air separation equipment, and currently sells more than 300 sets of air separation equipment to the outside world, and has formed a series of exclusive patents related to the manufacturing of gas equipment and gas production process. By the end of 2024, Qiyuan has obtained a total of 30 invention patents, 16 utility model patents and 9 software copyrights.
Qiyuan's self-designed double distillation tower nitrogen production process has low energy consumption per unit of nitrogen production and high extraction rate, and the end product nitrogen purity of the high-purity nitrogen nitrogen generator is extremely high, reaching 6 N. The nitrogen generator can be matched with a high-purity oxygen tower, and the purity of the prepared high-purity oxygen can be up to 6 N.
The high-purity carbon dioxide device developed by Qiyuan itself uses food-grade carbon dioxide as raw material, and the purity can reach 6N after purification and distillation, which can meet the raw material index requirements of semiconductor customers.
Relying on its own helium separation technology, Qiyuan cooperates with domestic helium suppliers to strengthen the security of the domestic helium supply chain and ensure multi-channel supply, so as to escort the domestic semiconductor industry's sustained, steady and high-quality development.
Qiyuan's bulk gas station in Linyi, Shandong Province, has been in stable operation for 15 years, with zero safety and quality accidents during the operation period. Meanwhile, the electronic grade bulk gas stations in Shanghai and Taiyuan have started to operate smoothly, supplying 9N bulk gas products to semiconductor manufacturing customers 24 hours a day.
