Electrical field effect on CO2 absorption and chemisorption in a rectangular bubble column by COMSOL

Raman Kumar Singh1, Prakash Chandra Ghosh1, Venkatasailanathan Ramadesigan1
1Department of Energy Science and Engineering, IIT Bombay, Mumbai, India

The chemisorption and absorption of CO2 bubbles have been extensively studied and modeled in literature. CO2 gas is converted into aqueous CO2, which produces OH-, HCO3- and CO32- - ions in the solution. In this study, a 3D CO2 bubble column is simulated using COMSOL Multiphysics, ...
