What is bubble point pressure of oil?
The bubble-point pressure (Pb) of a hydrocarbon system is defined as the highest pressure at which a bubble of gas is first liberated from the oil. This important property can be measured experimentally for a crude oil system by conducting a constant-composition expansion test.
Why is the bubble point important?
Importance of Bubble Point Pressure Bubble point pressure is the pressure at which the first bubble of the gas will come out of the liquid oil solution (McCain, 1990). This will affect the oil effective permeability and in turn the oil production will diminish.
What is the difference between bubble point and boiling point?
The bubble point is the same as the boiling point for a pure liquid. But for a mixture, the bubble point occurs when enough energy is inputed for the mixture to first change phase (evaporate).
What is bubble point and dew point?
The bubble point is the point at which the first drop of a liquid mixture begins to vaporize. The dew point is the point at which the first drop of a gaseous mixture begins to condense.
Is bubble point greater than dew point?
The lower temperature, 60.23°C, is called the bubble point temperature (since it is the temperature at which the first bubble of vapor appears on heating). The upper temperature, 80.15°C, is called the dew point temperature because it is the temperature at which the first drop of liquid appears on cooling.
Is bubble point pressure the same as Vapour pressure?
The bubble-point pressure of a hydrocarbon liquid at a given temperature is the vapor pressure of that liquid at the same temperature. If the composition and temperature of a hydrocarbon liquid are known, its vapor pressure can be determined by calculating the bubble-point pressure.
What is the alternative name for bubble point temperature?
What is the alternative name for bubble point temperature? Clarification: Bubble point temperature is also called initial boiling point. It is the temperature at a given pressure, when a liquid consisting of two or more components is heated the first bubbles of the vapors are formed.
Is Bubble Point test destructive?
A bubble point test is a non-destructive method of integrity testing that allows the user to correlate their results with manufacturer-determined values that indicate proper function.
