Where can I get an enthalpy-concentration diagram for methanol-water system at 1 atm? I have searched for it and ended up getting two different diagrams. I need it quickly to complete design of distillation column within deadline. Please help.

Thank You for responding but I already downloaded it from google. The problem is that it is in FPS units and I will not be able to sit and convert every value as I have my values in SI units. Please check if you could provide the link of a chart with SI units. Or can you suggest a method for designing a packed column where I would not require the usage of this diagram?

Are you kidding ?  from cal/gm to KJ/kg  should not be so complicated : * 4.1868 .

For the method , refer to your textbook (Ponchon & Savarit method) .

I did not mean it that way. I would also have to convert mass fractions into mole fractions for each value. It is equivalent to drawing a new diagram.
