AZEOTROPE PREDICTION BY MONTE CARLO MOLECULAR SIMULATION [PDF]

Chemical Engineering Communications, 2012
This article presents a methodology for checking the existence of the azeotrope and computing its composition, density, and pressure at a given temperature by integrating chemical engineering insights with molecular simulation principles.

Homogeneity of the water+ethanol+toluene azeotrope at 101.3kPa [PDF]

Fluid Phase Equilibria, 2008
An all-glass, dynamic recirculating still equipped with an ultrasonic homogenizer has been used in the determination of the vapour-liquid equilibrium (VLE) and vapour-liquid-liquid equilibrium (VLLE).

Azeotropes and pseudo-azeotropes

Fluid Phase Equilibria, 1989
Abstract Liquid mixtures of azeotropic composition cannot be separated by evaporation, condensation or distillation, provided that these processes are entirely equilibrium controlled. If diffusion becomes rate controlling, too, the phase change at constant composition may occur at other than the azeotropic composition.

Locating all azeotropes in homogeneous azeotropic systems

Computers & Chemical Engineering, 1996
A global optimization based approach for finding all homogeneous azeotropes in multicomponent mixtures is presented. The global optimization approach is based on a branch and bound framework in which upper and lower bounds on the solution are refined by successively partitioning the target region into small disjoint rectangles. The objective of such an

Extractive distillation for CO2–ethane azeotrope separation

Chemical Engineering and Processing: Process Intensification, 2012
The separation of the CO2–ethane azeotrope using the hydrocarbon solvents through an extractive distillation process was simulated with the HYSYS 2004.2 software platform. The objective was to examine the optimum solvent amount and composition as well as
