Correlation of Viscosity of Aqueous Solutions of Alkanolamine Mixtures Based on the Eyring's Theory and Wong-Sandler Mixing Rule [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 2013
A viscosity model, based on Eyring’s absolute rate theory combined with a cubic PR equation of state and Wong-Sandler mixing rule, has been proposed in order to correlate viscosities of aqueous solutions of alkanolamine mixtures at atmospheric pressure ...

Determination and Calculation of Phase Equilibrium for Aqueous Ternary System (NH2)2CO+KCl+H2O at 283.15K [PDF]

open access: yesE3S Web of Conferences, 2020
The solid-liquid phase equilibrium for ternary system (NH2)2CO+KCl+H2O was determined by isothermal saturation method at 283.15K under atmosphere pressure. The isothermal phase diagrams was drawn in according to the measured solubility data.

Temperature Effect on the Interaction Parameters of GC-NRTL Model Using the Genetic Algorithm

open access: yesChemical Engineering Transactions, 2013
Liquid-liquid equilibrium data is imperatively needed for the design of separation processes, particularly solvent extraction. The experimental measuring approach is complex and costly for a great number of chemical systems, and hence the need for ...

A Modified van der Waals Mixture Theory for Associating Fluids: Application to Ternary Aqueous Mixtures [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 2012
In this study a simple and general chemical association theory is introduced. The concept of infinite equilibrium model is re-examined and true mole fractions of associated species are calculated. The theory is applied to derive the distribution function

Parametrization of the NRTL Model with a Multiobjective Approach: Implications in the Process Simulation

open access: yesThermo, 2022
Thermodynamics, as a scientific tool, advises on the control of variables involved in processes of different nature and is particularly useful in the design of equipment, or to obtain previous simulations. However, to generate more accurate models, an exact science is required.
