Removal of sulfur from gasoline is one of the major processes in refineries. Designing of removal process requires phase equilibrium data of the sulfur with various hydrocarbon systems. 3-Methylthiphene is an organic sulfur compound found in gasoline. In the present work VLE data of 3-Methylthiophene with various hydrocarbons were modeled using genetic algorithm. VLE data were modeled using Wil...

Solid-liquid equilibria for binary mixtures of {Methyl palmitate (1) + Naphthalene (2)} were measured using differential scanning calorimeter (DSC). Simple eutectic behaviours for this system are observed. The experimental results were correlated by means of the NRTL, Wilson, UNIQUAC and ideal models. The root-mean-square deviations of the solubility temperatures for all measured data vary from...

In order to reduce global CO2 emissions, capture based on absorption in an amine/water mixture is established method. To develop such processes, correct physicochemical properties like densities and viscosities are important.The first objective of this work explore mathematical correlations for fitting viscosity data aqueous Monoethanolamine (MEA) Methyldiethanolamine (MDEA). A second evaluate ...

The temperature dependent solubility of 18 organic compounds, which some are active pharmaceutical ingredients, was measured in 1,4-dioxane, toluene and cyclopentyl methyl ether over a range between 0 70 °C using turbidity method. the studied compounds three solvents increases with all binary solute-solvent systems, exhibit higher 1,4-dioxane than ether. non-ideal behaviour systems evaluated te...

the effect of magnetic field on the liquid-liquid equilibrium of two ternary systems (water + acetic acid + butyl acetate and water + acetic acid + dimethyl succinate) at 298.15 k under atmospheric pressure was investigated. the results obtained show that the strength of the magnetic field (0.02 t) affects the solubility of acetic acid in the used organic solvents. distribution coefficients and...

In this work, the performance of four electrolyte models for prediction the osmotic and activity coefficients of different aqueous salt solutions at 298 K, atmospheric pressure and in a wide range of concentrations are evaluated. In two of these models, (electrolyte Non-Random Two-Liquid e-NRTL and Mean Spherical Approximation-Non-Random Two-Liquid MSA-NRTL), association between ions of opposit...
