ASTM D3827 Test Method for Estimation of Solubility of Gases in Petroleum and Other Organic Liquids
4. Summary of Test Method
4.1 The solubility of gases in petroleum and other organic liquids may be calculated from solubility parameters of the liquid and gas. The parameters are given for several classes of systems and their use illustrated. Alternative methods for estimation of solubility parameters are described.
5. Significance and Use
5.1 Knowledge of gas solubility is of extreme importance in the lubrication of gas compressors. It is believed to be a substantial factor in boundary lubrication, where the sudden release of dissolved gas may cause cavitation erosion, or even collapse of the fluid film. In hydraulic and seal oils, gas dissolved at high pressure can cause excessive foaming on release of the pressure. In aviation oils and fuels, the difference in pressure between take-off and cruise altitude can cause foaming in storage vessels and interrupt flow to pumps.
