Hi dudes. I have recently programed under Visual Basic a program to calculate bubble Pressure, Temperature, dew Pressure, Temperature and Flash for a multicomponent mixture with a little database of some compounds and able to calculate fugacity coefficient and activity coefficients via Wlson method.

Now based on this for my final proyect from school, my job is to code a Rigurous Method for multicomponent Destilation like the Wank-Henke method.

My question is:
Can soemeone know or supply me a little more extensive database of compounds that has Wilson interaction parameters or for any other Activity coefficient Method???? (So i can calculate K values for non-ideal mixtures)


Becouse i only got 5 pair of binary interaction parameters for Wilson on b00k of Smith Va Ness: "Intro. to Thermodynamics"

I dont want a big database becouse i dont have money to buy big professional DB packages like NIST or DICHEMA.

Plz i need more compounds with Wilson or NRTL or UNIFAC info necessary to extend my program.

Thanks in advance...
