Abstract
|
In this research, the gas-liquid absorption process is modeled in a hollow fiber membrane caller with a non-uniform flow pattern. modeling
A two dimensional math is considered for solving equations of mass balances. From pure water to the liquid phase in the membrane duct and pure 2CO
The gas phase is used in the shell section. Modeling by dividing the polyvinylidine fluoride membrane caller (PVDF) asymmetrically into four
Shell section, dense layer of membrane surface, membrane block and tube were performed. By solving simultaneously the equations of equilibrium and mass balance on the component transmitted in
In these four regions, the concentration of 2CO was distributed in radial and longitudinal direction in the membrane modulus. The effect of the strength of the dense layer of the membrane surface on the zinc
These concentration profiles were considered using the series resistance model and taking into account the effective porosity of the surface. The results of this simulation with data
Laboratory showed very good agreement. The results of the modeling showed that the increase in fluid velocity resulted in an increase in the 2CO CO 2 absorption flux.
