Abstract

The invention relates to a method of operating a liquid ring compressor having an impeller installed eccentrically in a compressor body, with gas being supplied to the liquid ring compressor on a suction side and gas being discharged from the liquid ring compressor on a pressure side. A liquid ring is generated in the liquid ring compressor on the inside of the compressor body by rotation of the impeller. Chambers are formed between blades of the impeller and the liquid ring and gas is drawn into these. The gas is compressed in the chambers which become smaller from the suction side to the pressure side as a result of the rotation of the eccentrically mounted impeller. The compressed gas is ejected on the pressure side. An ionic liquid is used as service liquid for generation of the liquid ring.
