A method and device for compressing a gas-phase medium, particularly hydrogen or natural gas, wherein the medium may have a water content up to total saturation with water and wherein the medium is compressed in a single or multiple stages in at least one liquid-filled chamber. The liquid(s) that is/are used are an ionic liquid that is not susceptible to attack by the water contained in the medium to be compressed and/or a liquid with low vapor pressure that is not susceptible to attack by the water contained in the medium to be compressed, and the compressed medium undergoes a water separation stage.

Compression of a water-saturated medium

A method and a device for compressing a gas-phase medium, particularly hydrogen or natural gas, in a single-stage or multistage process using at least one piston compressor, wherein the medium may have a water content up to total saturation with water. The medium to be compressed is heated before the compression at least to such point that the water is unable to condense out during the compression process, and the compressed medium undergoes a water separation process.

Compression of media

An arrangement for guiding a medium, preferably compressed, gaseous hydrogen, is described. The arrangement encompasses a medium line, a cooling medium return line which surrounds the medium line, and a cooling medium feed line. The cooling medium return line and the cooling medium feed line are hereby preferably arranged in direct heat contact. The arrangement can furthermore be surrounded by a jacket tube.
