The remarkable performance lays a solid foundation to promote the progress of the industry. In September 2021, PKU Pioneer’s VPSA industrial oxygen production project was put into operation in Golmud, Qinghai-Tibet Plateau, a place with the highest altitude in China. Since oxygen is scarce in plateau areas, to generate equivalent oxygen, more air has to be fed than in plain areas. The design capacity of the VPSA oxygen system is 4100Nm3/h with the purity of 93%. The practical oxygen flow reached 4222Nm3/h, with 3% overproduction, and in addition, the oxygen purity reached 93.67%. This means that VPSA oxygen units in China, medium or large-sized, have achieved stable 93% oxygen supply for non-ferrous metal smelting under the alpine and anoxic environment in plateau areas. The performance indicators, such as the oxygen capacity, purity, unit power consumption, etc. of the project have always remained stable and were even better than the design values. It helps to save the oxygen cost for the customer and enhance the comprehensive benefits, which is the biggest highlight of the project.

Apart from a series of breakthrough projects such as ultra-intelligent control, ultra-large oxygen capacity, and ultra-short construction period, PKU Pioneer is also striving to expand the application fields and scenarios of VPSA oxygen generation technology. In October 2021, the company signed a cooperation agreement with CATL, a leader in new energy batteries, to supply the client with VPSA oxygen generators. The product oxygen is designed to be used as the protective gas in the production process of lithium battery pole pieces, which is the first time to apply VPSA oxygen plant to provide the protective gas in the lithium battery industry.
