A novel methodology in design and simulation of membrane-based purification of organic solvents is proposed. A solution of water and alcohol served as model feed. Mass transfer and momentum transfer equations were derived and solved numerically to obtain the process output as function of process parameters. Water was taken as penetrant throughout the simulations. The studied process was pervaporation in which a nonporous polymeric membrane is used for purification of ethanol. Feed inlet concentration and velocity were considered as process input, water outlet concentration and removal efficiency as output. The Maxwell-Stefan mass transfer approach was applied for estimation of diffusion, the finite element approach for numerical simulation of the process. A lower feed velocity increased the water removal efficiency.

“…Although comprehensive 2-D model was developed and simulated for gas absorption [27][28][29][30], simulation of mass and momentum transport of liquid-liquid extraction, in general, and of copper (II) extraction, in particular, through HFMC is lacking in literature. Marjani and Shirazian [31], Rezakazemi et al [32] and Nosratinia et al [33] studied the numerical simulation of ammonia removal from wastewaters using membrane contactors. Ghadiri and Shirazian [34] investigated computational simulation of mass transfer in extraction of alkali metals through membrane contactors.…”

This work describes the mathematical modelling and numerical simulation of a hollow fiber membrane contactor for copper (II) extraction from aqueous solutions with 1,1,1-trifluoro-2,4-pentanedione commonly known as TFA diluted in n-decanol. Model was developed for convection-diffusion mass and momentum transfer using continuity and Navier-Stokes equations. Model equations were solved using a computational fluid dynamics code, and results were validated with experimental data. After validation of model, simulation was performed to check the effects of hydrodynamics conditions on contactor performance. 49% of copper (II) was extracted from aqueous solution for feed flow rate of 8.3 × 10 -7 m 3 .s -1 , and for partition coefficient equals to 1. However, simulation results indicated that extraction could be greatly improved by decreasing feed flow and increasing partition coefficient. Simulation was also run to study the distribution profiles of copper (II) concentration, flux and velocity in 2-D.
