Please, I need some data about Wilson K-Value methods, I'm using Chemcad 6.01.
If it is possible to post me the equation for this method or can anyone tell me how to find it on internet.

Have you ever heard of Google? Here's a link to the first "hit".

Thank you very much Latexman I really appreciate your help but if it is possible to post me more about Wilson method I mean dhe equation of state by Wilson. I need for my thesis so I have to write about this medhod. The topic is "Simulation of distillation coulmn" and the sources that I've been consulting are on attachment.
Once again, thank you for your help.
best regards

Are you talking about the Becker-Kistiakowsky-Wilson equation of state? Again, google it. I got 110 hits when I googled "Becker-Kistiakowsky-Wilson equation of state". When I looked at your attachment it seems to me you want the Wilson equation for vapor-liquid equilibrium, not an equation of state. Are you sure what you are looking for?

Yes that’s it Latexman I want the Wilson equation for vapor-liquid equilibrium. If it is possible to post me more about this method, as I said I need for my thesis I have to write a one page report. Once again, thank you very much for your help.
Best regards,

Are you looking to understand how to use the Wilson equation to obtain VLE data, or are you simply after interaction parameters? Which "Wilson" equation are you using? The one I'm most familiar with is Wilson's expression for excess Gibb's free energy that is usually used when modeling VLE with activity coefficients.
If you are looking for instruction on how the Wilson activity coefficient equation is used, you can try just about any thermo text. The ones I'm familiar with are Molecular Thermodynamics of Fluid Phase Equilibria by Prausnitz. Prausnitz also is co-author of The Properties of Liquids and Gases which has a section on VLE calculations. There's also Phase Equilibria in Chemical Engineering by Stanley Walas.
If you are looking for interaction parameters, I would start with DeChema Chemistry Data Series compilation of VLE data.

Thank you very much dear MrShorty
Dear MrShorty I just need to know what does mean Wilson method according ty my simulation example and to understand how to use the Wilson equation to obtain VLE data. Please can you post me links for books that you mentioned above. Once again thank you very much I appreciate your help

I'm not sure what kind of link you are looking for. Maybe try books.google.com and enter the title as your search term.
