Abstract
A sealing device for sealing a rotatable shaft of a gas compressor and/or a gas expander may include first and second sealing chambers and an extraction unit. The first sealing chamber may surround the rotatable shaft and include an inlet for the supply of a sealing medium. The second sealing chamber may be separated from the first sealing chamber by a seal and may surround the rotatable shaft. The second sealing chamber may include an outlet for the discharge of the sealing medium. The extraction device may extract the sealing medium out of the second sealing chamber. The present disclosure also concerns a corresponding method. Still further, the present disclosure concerns an installation for producing nitric acid with a NO compressor and a residual gas expander as well as a corresponding method. The NO compressor and/or the residual gas expander may have such a sealing device.
