Patent ID: 7927080

Claim:
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 ejected from the liquid ring compressor on a pressure side, which comprises the following steps: i) generating a liquid ring on the inside of the compressor body by rotation of an impeller mounted eccentrically in the body, ii) drawing of gas into chambers formed between blades of the impeller and the liquid ring, iii) compressing the gas in the chambers which become smaller from the suction side to the pressure side as a result of the rotation and the eccentric positioning of the impeller, iv) ejecting the compressed gas on the pressure side and passing the gas ejected on the pressure side to a liquid precipitator, wherein an ionic liquid is used as service liquid for generation of the liquid ring.
