In the operation of centrifugal and piston compressors on natural gas transmission lines, it is found that air, moisture, and hydrogen sulfide get into the lubricating oil. These contaminants, especially hydrogen sulfide, affect the lubricating properties of the oil to a great degree; however, this problem, which is directly related to the operating reliability of the moving parts of compressors, has not been studied adequately. Oxygen dissolved in the oil forms an iron oxide film on rubbing metal surfaces, protecting them from wear. When no oxygen is present, the wear becomes much more severe, all the way up to grabbing of the rubbing surfaces and pitting. Oil contaminants that form surface films with a different composition and structure, for example oxysulfide films, have received less attention. Using a procedure that we had developed, in which the oil can be saturated with hydrogen sulfide or other gases, we investigated the effects on wear rate and coefficient of friction from the presence of corrosive contaminants that find their way into turbine oil in the process of natural gas transmission.
