Effects of membrane properties on CO2 recovery performance in a gas absorption membrane contactor

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...

Effect of Polymer Concentr ation on the Structure and Performance of Polysulf one Flat Membrane for CO 2 Absorption in Membrane Contactor

Modeling and Experimental Study of Carbon Dioxide Absorption in a Flat Sheet Membrane Contactor

comIn the present study, CO2 removal from natural gas stream has been studied using a flat sheet membrane contactor. A three dimensional mathematical model is developed to describe the process. The model considers the transport of a gas mixture containing carbon dioxide and methane through a flat sheet membrane contactor module. The model is based on the non-wetted mode of operation, in which t...

Amine 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...

Regeneration 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...
