Modeling of <i>n</i>-Paraffin Cracking with Vapor-liquid Equilibrium

Liquid - Vapor Equilibrium/Distillation

Background The volatility of a compound is its ability to change into a vapor, or to evaporate at a particular temperature and pressure. The normal boiling point of a liquid usually allows comparison of its volatility to other materials, with lower boiling points indicating greater volatility, but this may be affected somewhat by the presence of other materials. Comparison of the concentration ...

Harmony Search for Parameter Estimation in Vapor- Liquid Equilibrium Modeling

This study introduces the application of Harmony Search (HS) method for solving the parameter estimation problem in vapor-liquid equilibrium data modeling. The performance of this novel stochastic optimization strategy has been tested using several sets of binary vaporliquid equilibrium data with local composition models and the classical approach of least squares. Our results indicate that HS ...

Liquid-Liquid Equilibrium for the Ternary Systems of Solvent+ m/o/p-Cresol+Water: Thermodynamic Modeling

In this study, NRTL and UNIQUAC thermodynamic models were used to predict the composition of ternary mixtures of solvents+ m/o/p-cresol+ water in organic and aqueous phases. Various solvents are used for the separation of cresols from water. In this study, methyl propyl ketone, methyl isopropyl ketone, methyl butyl ketone, and methyl isobutyl ketone solvents were investigated. Intermolecular in...
