Dilution Effects of Gasses on Lubricating Oil in a Recip Compressor
Under pressure, carbon dioxide and natural gas have been suspected of lowering the viscosity of lubricating oil in a compressor. The data and research to support this theory is for the most part unavailable. There have been some investigations with gas dilution but only at pressures below about 350 psi and most of this research is proprietary to the companies that have conducted it. There is ongoing bearing research dealing with very high pressures on lubricating oil. These pressures are around 250,000 psi. Experiments were conducted from 0 to 3500 psi using industrial rust and oxidation inhibited (R&O) lubricating oil diluted with carbon dioxide gas and hydrocarbon gas. The findings of these experiments attempted to measure viscosity changes of the oil due to increased pressure.
