I am calculating relief cases for a system with a water HC mixture. My question is does anyone have a good idée how to calculate the heat of vaporisation for the mixture?
If I take the enthalpy of the mixture in vapour phase (at due point) minus enthalpy of the mixture in liquid phase (at bubble point) I will get some kind of average of the required heat input to evaporate the mixture (and rise the temperature). But the actual heat of vaporisation can change a lot from start to the end.
