Editing Buffer gas (section)

=== Industrial ===
Buffer gases are also commonly used in [[Gas compressor|compressors]] used in [[power plants]] for supplying gas to [[gas turbines]].  The buffer gas fills the spaces between [[seal (mechanical)|seal]]s in the compressor.  This space is usually about 2 micrometres wide.{{Citation needed|date=April 2024}}  The gas must be completely dry and free of any [[contaminants]].  Contaminants can potentially lodge in the space between the seal and cause metal to metal contact in the compressor, leading to compressor failure.{{Citation needed|date=April 2024}}  In this case the buffer gas acts in a way much like oil does in an automotive engine's [[Bearing (mechanical)|bearings]].
