Abstract: In the this paper, the development, equipment characteristics, and the process feature of pressure swing adsorption for oxygen generation technology as well as its application in metallurgical field were introduced. After equipped with the VPSA of ZO-1X6000/93 system in ultra-high power electric arc furnace of 100 t Consteel in Guiyang Minda Iron and Steel Co., Ltd., it is found the oxygen utilization increased by 22.31%, smeltingelectricity consumption decreased by 10.69 %, oxygen cost decreased by 82.88 %, and the smelting time reduced by 4 min, which contributes to the improvement of economic returns largely.

Key words: pressure swing adsorpition, oxygen generation, VPSA, electric arc furnace steelmaking
