Modeling the absorption of CO2 in solvents enhanced by nanoparticle in polymeric membranes

Abstract

Lately nanomaterial received substantial consideration by several researchers. Solid nanoparticles prove to have extensive applications in composite materials and in the enhancement of mass and heat transfer. Adding nanoparticles to a base fluid improves the performance of mass and heat transfer. The effect of the addition of nanoparticles to base fluids, such as pure water and aqueous sodium hydroxide, show significant improvement in the percent removal of carbon dioxide from a gas composed of 15% CO2 balance is CH4 using gas-liquid hollow fiber membrane contactor. Results reveal that the rate of absorption of carbon dioxide increases with an increase in the concentration of nanoparticles up to certain extent beyond which insignificant removal rate is observed. Predicted results revealed that the percent removal of CO2 in the existence of CNT and NaOH is 35% and 40%, respectively.
