Mathematical Modeling and Numerical Simulation of CO2 Removal by Using Hollow Fiber Membrane Contactors
Abstract In this study, a mathematical model is proposed for CO2 separation from N2/CO2 mixtureusing a hollow fiber membrane contactor by various absorbents. The contactor assumed as non-wetted membrane; radial and axial diffusions were also considered in the model development. The governing equations of the model are solved via the finite...
متن کاملModeling and Simulation of CO2 Absorption Enhancement in Hollow-Fiber Membrane Contactors using CNT–Water-Based Nanofluids
Absorption of CO2 from a gas mixture containing CO2 and nitrogen by water-based CNT nanofluids in gas–liquid hollow fiber membrane contactor was modeled and solved using COMSOL Multiphysics 5.4. The model assumed partial wetting of the membrane, along with diffusion in the axial and radial directions. In addition, Brownian motion and grazing effects were both considered in the model. The main c...
متن کاملMembrane Based Co2 Removal from Spacesuits
INTRODUCTION Closed loop life support systems, such as in spacecraft or space suits, require removal of carbon dioxide and water vapor from the atmosphere. A membrane device that separates CO2 from breathing air can effectively control CO2 levels by venting the carbon dioxide directly to the vacuum of space. Such a membrane device requires no regeneration and therefore imposes no limitation on ...
متن کاملDevelopment and validation of a dynamic model for regeneration of passivating baths using membrane contactors
This work aims at the development of a dynamic model for the mathematical description of facilitated transport separation processes carried out in membrane contactors where mass transport phenomena are coupled with chemical reactions. A general model that takes into account the description of all possible mass transport steps and interfacial chemical reactions is initially presented, allowing i...
متن کاملSeparation of Carboxylic Acids from Aqueous Solutions using Hollow Fiber Membrane Contactors
Separation of formic, acetic, and propionic acids from the aqueous stream using membrane solvent extraction has been studied using three different membrane contactors made of polysulfone (PS), polyethersulfone (PES), and polyvinylidene fluoride (PVDF) using two different solvents; including ethyl acetate (EA) and diisopropyl ether (DIPE). The efciency of the membrane and e...
