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 کاملCO2 Capture by Dual Hollow Fiber Membrane Systems
In this paper, a system for efficient removal of carbon dioxide by hollow fiber membranes is proposed. The system is compact, and it is very useful for application in the offshore energy industries. In particular, it is used to removing CO2 from the exhaust of power generation facilities on offshore platforms.The proposed dual membrane contactor contains two types of membranes (polypropylene me...
متن کاملCFD Modeling of Hollow Fiber Membrane Contactor for Post-Combustion CO2 Capture
Due to its non-dispersive contact, definite interface and high specific volume, a membrane contactor offers many advantages over conventional contactors. In recent years it has been established as a potential replacement for packed absorber columns in the field of CO2 capture. There are many different configurations in which a membrane contactor can operate, while tubular membrane with liquid i...
متن کاملEffect of Ethylene Glycol as Pore Former on Polyphenylsulfone Hollow Fiber Membrane for Crude Palm Oil Deacidification through Membrane Contactor
In this study, polyphenylsulfone (PPSU) hollow fiber membrane was fabricated via a wet spinning method with the addition of ethylene glycol (EG) in the range of 0-10 wt% as the additive. The EG was added to improve the membrane pore formation and interconnectivity for better membrane contactor performance in extracting and removing the free fatty acid (FFA) from crude palm oil (CPO). Four diffe...
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...
