Improved binary parameters using GA for multi-component aromatic extraction: NRTL model without and with closure equations
TL;DR: In this article, the binary interaction parameters based on non-random two liquid (NRTL) activity coefficient model have been estimated using GA, without and with closure equations for 65 multi-component aromatic extraction systems: 53 ternary, 9 quaternary and 3 quinary systems.

UNIQUAC Interaction Parameters with Closure for Imidazolium Based Ionic Liquid Systems Using Genetic Algorithm
TL;DR: In this paper, the global optimization has been used for the prediction of UNIQUAC interaction parameters for ionic liquid-based systems, and the two concepts of closure equation and global optimization via GA have been benchmarked and tested on 88 aromatic and 28 hydrogen bonding multi-component systems.

Closure Equations in the Estimation of Binary Interaction Parameters
Syed Akhlaq Ahmad,Ashok Khanna +1 more
TL;DR: In this article, the binary interaction parameters have been estimated with and without closure equations for few ternary and quaternary systems, and they exhibit better root mean square deviation than those that do not satisfy the closure equations in most of the cases.

A direct method for calculation of liquid-liquid equilibria in multicomponent systems
A. Avijit Bhowal,D.P. Rao +1 more
TL;DR: In this article, a direct method for LLE calculations based on the Newton-Raphson method has been presented, and two initialisation schemes have been tried employing 21 systems, one gave convergence for all points, with a minor adjustment in a few cases, whereas Scheme 2 gave convergence in all but 3 cases.

Extraction Separation of Aromatics
TL;DR: In this paper , a survey of recent advances in the extraction of aromatics from aliphatics mixtures and the application of the extraction processes in the industry is presented, and the general trends for the above extractions are analyzed and the challenges of the separation process are evaluated.
