Abstract

Article history: This paper applies computational fluid dynamics (CFD) to explore a numerical simulation of mass Received 22 November 2015 transfer in a hollow fiber membrane contactor (HFMC) for non-wetted and partially-wetted conditions. Received in revised form 8 January 2016 A comprehensive 2D mathematical model based on the finite element method (FEM) was developed Accepted 19 February 2016 for modeling a gas–solvent HFMC which was applied to CO removal from a CO /N gas mixture. 2 2 2 Available online 5 March 2016 Aqueous mono-ethanol-amine (MEA) solution was used as the CO absorbent and flowed in the fiber bore and then the gas mixture was circulated counter-currently in the shell side of HFMC. The average Keywords: outlet CO concentrations, the absorption flux, overall mass transfer coefficient and the CO removal 2 2 Hollow fiber membrane contactor efficiencies are parametrically simulated by using the operational parameters such as gas and solvent CO capture flow rates, operating temperature, the fiber porosity and other geometrical characteristics. As a novel Computational fluid dynamics work, the effect of opposite fluid direction, i.e. absorbent flow in the shell and gas mixture in the Non-wetted conditions Partially-wetted conditions fibers, on the mass transfer coefficient and CO
