Abstract:
A three-dimensional (۳D) model was proposed for carbon dioxide (CO۲) capture from a gas mixture using a packed bed column. Nanofluids of graphene-oxide nanoparticles were used as absorbents. The governing equations were solved using computational fluid dynamics technique (CFD), while the concentration and velocity profiles were determined under different operating conditions. The increases in the capture efficiency for graphene-oxide/MDEA nanofluid with concentration of ۰.۰۵ vol% in comparison with bare MDEA was ۲۴.۳۰%. The obtained results from the proposed model were compared with the experimental data, which findings revealed that there was a good agreement between the CFD predictions and the experimental results.
