Numerical Simulation of Acetone Stripping from Water in a Microchannel Device

Abstract

A 2D mathematical model was developed in this study to simulate acetone separation from water by using a microstripper device. Model validation was implemented through a comparison of simulation results of acetone removal from water and experimental data for dry nitrogen over a wide range of carrier gas and liquid velocities. A comparison of experimental data and simulation results illustrated reasonable agreement. The results indicate that increasing the liquid velocity reduces the acetone removal rate because increasing liquid velocity results in a decrease in the residence time of liquid in the liquid channel, whereas there is an enhancement in acetone removal with increasing carrier gas velocity. A sharp decrease in acetone concentration in the liquid channel was observed.

Experimental Study and Artificial Intelligence Modeling of Dye Removal in Microfluidic Systems

“…Some of the advantages of this technology are easy process control, fast mixing, low costs, and capacity enhancement by parallelizing chips [8][9][10]. The small scale of the microchannels leads to a high surface contact area and a short diffusion path, which thereby enhances the mass transfer rate of fluids [11][12][13]. Many researchers have used microchannels for solvent extraction [14][15][16].…”

“…Great and irrefutable capabilities such as low investment cost, simple technology, high flexibility in system design and appropriate environmentally friendly characteristics have motivated numerous researchers for further investigations [7][8][9][10][11][12]. Various membrane separation processes have been designed and developed so far for purification/separation of gas and liquid mixtures [13][14][15][16][17][18][19].…”
