What is the meaning of bubble point?
bubble point in Chemical Engineering Bubble point is the temperature at which the saturated liquid starts to boil off its first bubble of vapor. The bubble point temperature is the temperature at which vapor first forms from a liquid.
Is the bubble point the same as the dew point?
In thermodynamics, the bubble point is the temperature (at a given pressure) where the first bubble of vapor is formed when heating a liquid consisting of two or more components. For a single component the bubble point and the dew point are the same and are referred to as the boiling point.
What is bubble point in phase diagram?
Bubble Point Curve—the curve that separates the pure liquid (oil) phase from the two-phase (natural gas and oil) region. This means that at a given temperature, when pressure decreases and below the bubble point curve, gas will be emitted from the liquid phase to the two-phase region.
How do you measure bubble points?
This measurement is taken from the downstream side of the filter housing where a flexible piece of tubing has been attached and the other end submerged into a beaker of water. The bubble point is indicated by vigorous bubbling from the tubing.
What happens at the bubble point?
The limits in the case of gas-liquid phase changes are called the bubble point and the dew point. The names imply which one is which: 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.
Why is bubble point important?
Bubble point pressure is the pressure at which the first bubble of the gas will come out of the liquid oil solution (McCain, 1990). The determination of the bubble point pressure in oil reservoirs is crucial because it will determine several aspects in the reservoir management strategy.
Which is the correct definition of the bubble point?
The bubble point is the temperature at which a solution makes the first bubble of vapor, commencing the vaporization of that solution (at constant pressure). If it is a pure liquid, then the bubble point is called the boiling point.
How is bubble point pressure related to dew point pressure?
Any flash separation divides the hydrocarbon system into two streams: a bubble-point stream and a dew-point stream. The bubble-point pressure of a hydrocarbon liquid at a given temperature is the vapor pressure of that liquid at the same temperature.
What makes an oil field have a bubble point?
At discovery, all petroleum reservoir oils contain some natural gas in solution. Often the oil is saturated with gas when discovered, meaning that the oil is holding all the gas it can at the reservoir temperature and pressure, and that it is at its bubblepoint. Occasionally, the oil will be undersaturated.
How is the bubble point of a filter determined?
Bubble point is a function of pore size, filter medium wettability, surface tension and angle of contact. The filter membrane is wetted and a gradual increasing gas pressure is applied. The bubble starts forming from the largest pore first. The gas pressure at this time is the bubble point for the membrane.
