SUMMARY

This discussion focuses on plotting Vapor-Liquid Equilibrium (VLE) using Wilson, Margules, and van Laar equations at a specified temperature, incorporating fugacity coefficients. Users seek guidance on executing these calculations and visualizations, with references to existing examples. The conversation emphasizes the importance of understanding these thermodynamic models for accurate VLE predictions.

PREREQUISITES
  • Understanding of Vapor-Liquid Equilibrium (VLE) concepts
  • Familiarity with Wilson, Margules, and van Laar equations
  • Basic knowledge of fugacity coefficients in thermodynamics
  • Proficiency in plotting software or programming languages (e.g., Python, MATLAB)
NEXT STEPS
  • Research the implementation of Wilson, Margules, and van Laar equations in Python
  • Learn how to calculate fugacity coefficients for different systems
  • Explore graphical libraries for plotting VLE data (e.g., Matplotlib, Seaborn)
  • Review case studies or worked examples of VLE calculations
USEFUL FOR

Chemical engineers, thermodynamic researchers, and students studying phase equilibria who need to understand and apply VLE modeling techniques.

Using the equations Wilson’s, Margules’, and van Laar’s, plot the predicted VLE for this system at this temperature, with and without the use of fugacity coefficients.

Anyone know how to do this or can explain to me how to do VLE. Or have a link for a worked example.

Cheers.
