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
