2023 is a year full of challenges and opportunities for PKU Pioneer. In the face of global economic instability and increasingly fierce market competition, PKU Pioneer's main business, vacuum pressure swing adsorption (VPSA) and pressure swing adsorption (PSA)gas separation, once again achieved impressive results. With sales revenue of nearly $104 million, up 17% year-on-year, PKU Pioneer achieved solid growth throughout the year.

PKU Pioneer has been deeply engaged in the steel industry for nearly 25 years and is committed to providing steel enterprises with economical, efficient and reliable VPSA (Vacuum Pressure Swing Adsorption) and PSA (Pressure Swing Adsorption) oxygen generation equipment. Up to now, PKU Pioneer has constructed oxygen plants for nearly 70 top steel mills around the world, helping them save nearly 30% of comprehensive energy consumption. Among them, a VPSA oxygen unit set up by PKU Pioneer for a steel mill in China has achieved a new breakthrough- the total oxygen capacity reached 100,000Nm3/h.

Oxyfuel combustion technology refers to using industrial oxygen instead of air to burn fuels. Compared with the traditional air-fuel combustion technology, the "oxygen + fuel" mode changes the combustion medium from air to oxygen, which reduces the introduction and removal of N2 by about 78% and improves the flame temperature as well as heating efficiency, thus greatly lowering the amount of flue gases and venting heat loss, etc.

A steel company in China reformed its 3 ladle heating systems (120t). The former natural gas combustion supported by air was upgraded to oxyfuel combustion, i.e., the natural gas is assisted by 91% oxygen gas supplied by a VPSA oxygen unit. The oxygen capacity of the VPSA oxygen generation system is 800Nm3/h with a purity of ≥91% taking into consideration the simultaneous usage of 3 ladle heaters and the available residual O2 replenishment in the steel mill.

On December 10, 2023, 2 sets of VPSA oxygen plants (5556Nm³/h, 90%) built by PKU Pioneer for Gansu Jinchuan Group were successfully started up to provide stable oxygen for nickel flash smelting furnace and copper synthesis furnace.

PKU Pioneer hereby launches the steel industry promotional video (2023 new version)! PKU Pioneer has been promoting the application of VPSA (Vacuum Pressure Swing Adsorption) and PSA (Pressure Swing Adsorption) oxygen generation technology, low-carbon utilization technologies of steel exhaust gases, and dry fine desulfurization technologies in the steel sector. Driven by the "dual-carbon" strategy, and to create a low-carbon future, PKU Pioneer will be given unlimited opportunities to lead us to march forward together with the world's iron and steel enterprises!
