Saturated vapor pressure of the mixture
Thread Content
Is the saturated vapor pressure of the mixture at the bubble point temperature or at the dew point temperature? Can it be calculated using the ASPEN flash module?
The bubble point temperature can be calculated using flash evaporation
It depends on what kind of mixture it is; if it’s a conventional one, an approximate estimate can be made. Additionally, the vapor pressure of the mixture can be determined through theoretical calculations.
“The saturated vapor pressure of a mixture is at the bubble point temperature,” and this holds only in the case of completely miscible systems； If stratification occurs, as in a \"water/oil\" system, the vapor pressure is essentially equal to the vapor pressure of the light-phase component, and at this point the meaning of \"saturation\" becomes quite ambiguous – has equilibrium been reached in terms of dissolution? Or is the temperature close to the boiling point of the light-phase component?
It’s not easy to simulate; I’m not sure what method to use :)
