Linde's developed "ionic compressor" based on ionic liquid
Author: Release time:2014-04-18 13:45:08 Reading times:
Linde have developed a device that they call an ‘‘ionic compressor’’. It is a machine for compressing gases at constant temperature (isothermal compression) and high pressure, using the ionic liquid as a type of liquid piston (ionic liquids have a very low compressibility). Linde state that ‘‘in contrast to a conventional piston compressor, with some 500 moving parts, we now need only eight.’’ The system maintains a constant gas pressure of 250 bar while delivering 500 cubic meters of natural gas per hour. The proposed early applications are dihydrogen and natural gas filling stations.
