How does Aspen display the vapor pressure calculation results?

Aspen only has the vapor pressures for individual components built in; during calculations, the molar fraction of each substance must be multiplied by its partial pressure (under ideal conditions). However, multiplying by γ is still required to obtain the vapor pressure for that specific composition. Could someone please provide the method for calculating the vapor pressure for each stream? If γ is not used, Aspen may calculate that a liquid phase exists when in fact, using the vapor pressure multiplied by the molar fraction, that stream should be considered gaseous. This has a significant impact on the engineering design. Last edited by attrition on 2009-3-27 13:08.]
