I am analyzing the role that different solvents play in the extraction of certain organic compounds. As a part of my analysis, I want to compare what would be the energy duty if I was to proceed the distillation to obtain those compounds using the analyzed solvents. Is it reasonable to calculate it by the difference between the (solvent) enthalpy at room temperature and the enthalpy of vaporization (for each respective solvent)?
Important: This calculation is meant to be a rough estimation for an energy balance analysis, not for the design of the distillation column.
Thanks!

If you're doing a practical, not a simulation, then you might want to involve some thermodynamic equations in your work.
If it was a simulation it could've been easier to calculate the energy requirement for every other solvent..
Hope it helps.
For your analysis with the enthalpy of vaporization of the solvent is sufficient. The energy needed to bring a solution, mostly solvent, to the bubble point is negligible compared to the energy needed to vaporize it.
