Correlating Physicochemical Properties of Commercial Membranes with CO2 Absorption Performance in Gas-Liquid Membrane Contactor
The gas-liquid membrane contactor (GLMC) is a promising alternative gas absorption/desorption configuration for effective carbon dioxide (CO2 ) capture. The physicochemical properties of membranes may synergistically affect GLMC performances, especially during the long-term operations. In this work, commercial polypropylene (PP) and polyvinylidene fluoride (PVDF) hollow fiber (HF) membranes wer...
متن کاملRegeneration of СO2 Physical Solvents at Elevated Pressures in Gas-Liquid Membrane Contactor
In the present work, a membrane contactor with asymmetric flat-sheet poly(vinyltrimethylsilane) (PVTMS) membranes was proposed for the CO2 desorption process from physical solvents at elevated trans-membrane pressures. Different solvents were studied: water, a mixture of polyethylene g...
متن کاملSeparation and Fixation of Carbon Dioxide Using Polymeric Membrane Contactor
Polypropylene hollow fiber membrane (PPHFM) contactor, with aqueous solution absorbent such as sodium hydroxide (NaOH), monoethanolamine (MEA) and diethanolamine (DEA), was designed and used to separate and fix CO2 from CO2/N2 gas mixtures. The factors that influence the separation properties of CO2/N2 were investigated. It was found that the CO2 removal efficiency is the best by using MEA solu...
متن کاملAmine Based CO2 Absorption in Membrane Contactor Using Polyvinyl Pyrrolidone-modified Polysulfone Flat Sheet Membrane: Experimental Study and Mass Transfer Resistance Analysis
Membrane contactor using amine based absorbents is an efficient technology for CO2 separation from gaseous mixtures. A novel porous polysulfone (PSF) flat membrane was prepared via non-solvent phase inversion method. The PSF membrane was modified by adding polyvinyl pyrrolidone (PVP) to the dope solution. The fabricated membrane was used in the serpentine flow field contactor module for CO2 abs...
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...
