Apply Solubility Theory for Process Improvements
Michael J. Gentilcore
For solid compounds that dissolve in solvents but do not ionize, the thermodynamics of solubility can provide valuable predictions and insights.

Accurately Predict the VLE of Thiol-Hydrocarbon Mixtures
Chorng H. Twu, Vince Tassone, Wayne Sim
This methodology can be used to calculate vapor-liquid equilibria (VLE) between thiols and hydrocarbons at any composition, temperature or pressure to improve gasoline fractionation processes.
Troubleshooting Distillation Simulation
Stanislaw K. Wasylkiewicz
A tool called azeotrope pressure sensitivity analysis (APSA) can shed light on the dependence of an azeotrope's composition and temperature on changes in pressure.
Understanding Crystallization and Crystallizers
Ketan D. Samant, Lionel O'Young
Gain qualitative insight into the basic mechanisms of crystallization, the principles of crystallizer operation, and the ways in which these concepts relate to the selection and application of the various crystallizer configurations in industrial...
A Simple Approach to Vapor Pressure Prediction
Andrew J. DeDoes, Matthew D. Goetz, Michael J. Misovich
This method reproduces the vapor pressure predictions of the Soave-Redlich-Kwong and Peng-Robinson equation of state with a simple Antoine equation that uses constants derived from critical properties and the acentric factor.
