Liquid-liquid equilibrium (LLE) problems such as phase stability analysis, phase equilibrium calculations, chemical equilibrium calculations, binary interaction parameter identification of thermodynamic models and other problems of fluid characterization have been the core subject of many recent studies. This study introduces Cuckoo Search (CS), Firefly Algorithms (FA) and its variants as p...

Carbon dioxide (CO2) transformation into added-value products through non-thermal plasma (NTP) represents a novel technology of interest. The process involves, apart from CO2, mixtures different gases such as carbon monoxide (CO), oxygen (O2), nitrogen (N2), argon (Ar), and hydrogen (H2) for subsequent CO2 methanation. In this work, preliminary study the thermodynamic representation relevant in...

The modified NRTL (m-NRTL) model is used to represent the excess Gibbs free energy of aqueous (alcohol + electrolyte) solutions. In this work, the m-NRTL model previously developed for representation of vapor-liquid equilibria for (polymer + salt + water) systems has been extended to represent liquid-liquid equilibria of (alcohol + salt + water) systems. The proposed extension is a modified of ...

Formation of gas hydrates in natural saturated with water threatens the integrity subsea pipelines, therefore effort must be put into inhibiting these processes. A commonly used inhibition method is dehydration triethylene glycol (TEG), which molecule interest this work. In our previous study, new multicomponent vapour-liquid-equilibria (VLE) data for TEG/water/natural systems were published, a...
