Carbon dioxide capture is on the top of the list in the climate change debate. The recent United Nations COP27 conference in Egypt highlighted the need for action and fund to combat the effects of climate change on the underdeveloped countries. Global warming requires a global solution or solutions. At the technology level, governments and private institutes are working towards finding these solutions. When it comes to testing these solutions, simulations are playing a major role in shortlisting from a ton of proposed solutions, so money is spent on the right technology that is effective and cheap to deploy. We present a numerical solution of a new design that captures carbon dioxide from flue gas. This is based on a rotating packed bed where solvent liquid (amine) and flue gas are made to pass through in a counter-flow setting. The CO2 gets absorbed in the solvent at the gas-liquid interface. Ansys CFD is used to calculate the interface area for different rotational speeds and flow rates. This is further expanded to include the mass transfer across the interface based on customized mass transfer rates based on experimental correlation. The study focuses on the most important parameters to reduce the number of simulations. The results are verified using measurement data from published literature. This study will use Ansys optimization tool to pick the most important design and process parameters to generate a reduced order model which can be used in the digital twin of the field asset.
