Abstract

A method of compressing oxygen includes passing the oxygen into a vessel 12 containing finely divided material. Next a driving gas, for example, air is compressed to a greater pressure than the oxygen and passed through the vessel 12 and the bed of material contained therein which creates a plug flow effect such that the oxygen is compressed by the air substantially without back-mixing.
