I have a DME (dimethyl ether)- methanol - water mixture with the mol fraction composition: DME 0.4295, methanol 0.1353, water 0.4351.
This mixture has a boiling temperature range: dew point 141.6 °C and bubble point 69.95 °C, and the heat applied for the phase change (condensation) is a latent heat. How can I calculate it?
I know that for pure compounds, during the condensation process, there's no temperature change, so the latent heat is the result of:
Q = mass flow * latent enthalpy (constant value)
For a mixture that has a condensation temperature range, can I use the same equation? If this is not the case, how can I calculate the latent enthalpy for a mixture in function of the temperature?
