How to calculate the saturated vapor pressure of a pure component in Aspen?
Thread Content
I want to calculate the saturated vapor pressure, for pure components or mixed components – how can I do this in Aspen? Thank you all.
This approach is feasible; alternatively, a flash module can be used – given the temperature and gas phase fraction, the pressure readout corresponds to the saturated vapor pressure...
I don’t fully understand the first two methods. Could you explain them? 1. It’s the pressure at which a fluid changes from a liquid state to a gas state. If the container is very small, wouldn’t the pressure be very high? 2. How is the vapor phase fraction determined?
The gas phase fraction is set to 1; Aspen is used for simulation, and there is no scenario with a small container – everything is idealized
I understand what the people upstairs meant; thank you very much, the issue has been resolved.
In the flash vaporization model, when the gas phase fraction is set to 1, the system is considered to be in a saturated state. The size of the equipment is determined automatically by the system, and the resulting pressure corresponds to the saturation vapor pressure.
