Ionic liquid piston compressor

When ionic compressor is a working isothermal displacement compressor ( liquid organic salts in the workspace) dissipates the heat produced during compression heat inside by an ionic liquid. These specially adapted to the specific purpose "designer liquid " can simultaneously clean the gas or gas mixture of aerosols, airborne particles or other particles and is able to selectively absorb gas components from gas mixtures.

In these compressors, a movable liquid column is used to compress the gas, instead of a movable piston, which is moved by a pump up and down. The liquid is connected to two pistons together. While the liquid column in the rising a cylinder, it decreases in the other cylinder. Since the compressor in addition to the pump for pumping the liquid does not contain any moving parts, are a number of problems of mechanical compressors, such as mechanical abrasion, and expensive cooling energy losses achieved.

An important field of application for these compressors is seen by the current developers Linde AG and Daimler AG in the compression of gases into hydrogen and natural gas filling stations. This compressor allows in combination with the existing reciprocating compressor in a hydrogen filling station a higher capacity for refueling.
