Performance enhancement of hollow fiber membrane contactors for CO2 absorption using MEA-based functionalized nanofluids
The performance of hollow fiber membrane contactor for CO2 removal using MEA-based nanofluid was experimentally evaluated. Different types of nanoparticles, including Al2O3, Fe3O4, and functionalized MWCNT in this study. The influence of various operating conditions including gas and absorbent flow rates, absorbent concentration, and nanofluid characteristics on separation performance was thoroughly examined. The results showed that compared to conventional amine solvents, the nanofluid absorbents significantly enhance CO2 absorption performance. In comparison to the base fluid, the mass transfer coefficient was raised by 320, 120, and 40% for 0.15 wt% MWCNT, Al2O3 and Fe2O3, respectively. The MWCNT showed much more compliance with amine solvents due to its carboxyl functional groups and higher surface area which make it more stable in a strong polar mixture. The study underscores the importance of stability, viscosity, and shear stress of nanofluids as key parameters affecting CO2 absorption performance.
期刊介绍：
Microfluidics and Nanofluidics is an international peer-reviewed journal that aims to publish papers in all aspects of microfluidics, nanofluidics and lab-on-a-chip science and technology. The objectives of the journal are to (1) provide an overview of the current state of the research and development in microfluidics, nanofluidics and lab-on-a-chip devices, (2) improve the fundamental understanding of microfluidic and nanofluidic phenomena, and (3) discuss applications of microfluidics, nanofluidics and lab-on-a-chip devices. Topics covered in this journal include:
1.000 Fundamental principles of micro- and nanoscale phenomena like,
flow, mass transport and reactions
3.000 Theoretical models and numerical simulation with experimental and/or analytical proof
4.000 Novel measurement & characterization technologies
5.000 Devices (actuators and sensors)
6.000 New unit-operations for dedicated microfluidic platforms
7.000 Lab-on-a-Chip applications
8.000 Microfabrication technologies and materials
Please note, Microfluidics and Nanofluidics does not publish manuscripts studying pure microscale heat transfer since there are many journals that cover this field of research (Journal of Heat Transfer, Journal of Heat and Mass Transfer, Journal of Heat and Fluid Flow, etc.).
