How should the heat of vaporization of a mixed gas be calculated

In the case of a safety valve operating in a fire scenario, the release rate needs to be calculated using the latent heat of vaporization. However, for mixtures containing multiple components, how can this latent heat be determined? Aspen simulations can only account for single components
Personal guess: The heat of vaporization per unit weight of a certain component should remain constant. Does this calculation require taking the heat transfer power into account? This power is equal to the sum of the vaporization heats of the various components in the mixture, and then the ratio of the gas components is determined based on Raoult’s law, so as to calculate the heat distribution
If no chemical reactions occur during the process of heat conversion and change, the total amount can be calculated as the sum of its components, but be aware that phase change heat may be involved.
Can’t HYSYS be used to calculate the vaporization latent heat of mixed phases? It is the sum of the latent heats of vaporization for each single phase, multiplied by their respective mole fractions
