Hi all,

 

I'd like any suggestions on literature where I can find equilibrium k-values (used in industry) for aromatics components,

 

Thanks!

Consider using the Student Forum at this site for student-related questions.

A component's K-value (the ratio of the mole fraction of a component in the vapor phase to the mole fraction of a component in the liquid phase) depends on system pressure and temperature so is usually predicted by a thermodynamic method previously found to give good results for similar applications. At low pressures, mixtures of aromatic components can be treated as ideal so you can calculate K from the partial pressures of the components. At higher system pressures, you will get more accurate results using an equation of state like PR or SRK.

Hi,

 

Refer the link below. The spreadsheet attached in the link has DePriester charts depicting K-values for hydrocarbons. Also extensive VLE K-values are provided in "API Technical databook":

Also refer another link for empirical method of calculating K-values for a given range of pressure:
