Experimental investigation on possibility of oxygen enrichment by using gradient magnetic fields

CAI Jun, WANG Li, TONG Lige, SUN Shufeng, WU Ping

Frontiers of Chemical Science and Engineering 2007, Volume 1, Issue 3,   Pages 271-276 doi: 10.1007/s11705-007-0049-x

Abstract: This paper presents a novel method that uses the interception effect of gradient magnetic field on oxygenmolecules to realize enrichment.Thus, continuous oxygen enrichment is realized.The enrichment degree of oxygen reaches 0.65% when the inlet and outlet air flows are 40 mL/min and 20enrichment degree than other oxygen-enrichment methods using magnetic separation.
