摘要

Method for compressing a gaseous, oxygen-containing medium, preferably oxygen, comprises condensing the medium by means of a liquid piston containing ionic liquid or a mixture of two or more ionic liquids. An independent claim is included for an operating liquid such as ionic liquid or a mixture of two or more ionic liquids, for an oxygen compressor, in which the condensation of a gaseous, oxygen-containing medium, preferably of oxygen, is carried out by means of at least a liquid piston.
