The boundary points between one and two phase regions must be determined in advance through bubble point and dew point calculations. For mixtures that consist of light gases or polymers, these …
WebThe bubble point test is a method for both characterising a particular membrane and also for testing the integrity of a membrane. The test is based on the fact that for a given fluid and membrane pore size and constant wetting the pressure required to force an air bubble through a pore is inversely proportional to the size of the pore or hole. WebNov 1, 2024 · The conventional industry method of determining bubble point pressure is two step procedure utilizing PV data obtained from the CCE test: The estimation of bubble point pressure by visual graphical analysis.

WebBubble point testing is a wire mesh integrity testing method that submerges a tensioned wire mesh sample into a wetting agent and subjects it to calculated pressure. This pressure is applied until bubbles begin to protrude out of the pore openings of the mesh, establishing the maximum capillary pressure. WebJul 1, 1992 · BUBBLE-POINT TEST METHOD. ARP901.
