1 1602 CHEMICAL INDUSTRY AND ENGINEERING PROGRESS TQ A Prospect of the structure of oxygen generating adsorber by pressure swing adsorption ZHANG Hui LIU Yingshu LIU Wenhai ZHANG Dexin ZHAI Hui School of Mechanical Engineering University of Science and Technology Beijing Beijng China Abstract The inner structure of adsorber flow distributor arrangement and packing style of molecular sieve impacting components of packing bed are introduced. The factors that have effects on the performance of oxygen generating system by pressure swing adsorption are analyzed and discussed and some key skills and lessons are shared in the design of the oxygen generating equipment. Key words pressure swing adsorption oxygen concentrator adsorber flow distribution plate molecular sieve Praxair APCI UCC LindeMesser Air Liquide Nippon Sanso Corporation Mitsubishi Heavy Industries E mail zhanghui56@me.ustb.edu.cn
