CO2 separation from gaseous mixtures in a hollow‐fiber membrane contactor (HFMC) with conventional solvents has a high energy cost. Aqueous ammonia is an industrial solvent candidate that provides better features. A mass transfer model was developed to investigate the effect of operating parameters on the separation performance of an HFMC using aqueous ammonia for CO2 removal. The governing equations were solved numerically. The influence of the liquid flow rate, liquid concentration, and gas flow rate on CO2 removal was studied at different CO2 inlet concentrations. The liquid flow rate had a slight effect on the CO2 concentration at the shell exit, while the CO2 removal significantly changed with variation of the gas flow rate. Moreover, the proposed model can predict CO2 removal as well as axial and radial CO2 concentration profiles in the HFMC as a function of the main operating parameters.

The membrane gas separation process has gained significant attention using the computational fluid dynamics (CFD) technique. This study considered the CFD method to find gas concentration profiles in a hollow fiber membrane (HFM) module to separate the binary gas mixture. The membrane was considered with a fiber thickness where each component’s mass fluxes could be obtained based on the local partial pressures, solubility, diffusion, and the membrane’s selectivity. COMSOL Multiphysics was used to solve the numerical solution at corresponding operating conditions and results were compared to experimental data. The two different mixtures, CO2/CH4 and N2/O2, were investigated to obtain concentration gradient and mass flux profiles of CO2 and O2 species in an axial direction. This study allows assessing the feed pressure’s impact on the HFM system’s overall performance. These results demonstrate that the increment in feed pressures decreased the membrane system’s separation performance. The impact of hollow fiber length indicates that increasing the active fiber length has a higher effective mass transfer region but dilutes the permeate-side purities of O2 (46% to 28%) and CO2 (93% to 73%). The results show that increasing inlet pressure and a higher concentration gradient resulted in higher flux through the membrane.

Membrane contactor has emerged as a promising technology for flue gas carbon capture as it integrates the advantages of high capture efficiency of absorption technology and compact design of membrane technology. However, the integration performance could be affected by the presence of minor components such as water vapor and residual oxygen in real gas conditions, owing to vapor condensation and dynamic oxidation in gas‐liquid transfer interface. Therefore, it remains a need to develop a model that enables the prediction of CO2 removal performance of membrane contactor under industrial real gas conditions. In the present study, a multicomponent model considering the impact of water vapor and oxygen on CO2 removal in membrane contactors was developed. The model, based on mass transfer equilibrium, gas reaction kinetics, and diffusion coefficients, describes the transport and reaction dynamics of multicomponent gases within the gas, liquid, and membrane phases. Utilizing the finite element method (FEM) for solution, the model was demonstrated with a case study of CO2 separation from a quaternary gas mixture by a hollow fiber membrane contactor (HFMC). The results highlight the importance of considering water vapor and oxygen in the design and evaluation of industrial membrane contactor systems, offering valuable insights for enhancing CO2 separation efficiency in practical applications. © 2024 Society of Chemical Industry and John Wiley & Sons, Ltd.
