A Mathematical Model for CO2 Capture via Mineral Carbonation Using Hydrated Lime

Year: 2025

Type: conference-paper

Abstract: The construction sector contributes to approximately 37% of global GHG emissions. To mitigate this impact, this study develops a mathematical model to analyze CO2 capture via hydrated lime carbonation. The model integrates reaction kinetics, diffusion and heat balance, considering the effects of liquid water saturation, the influence of porosity on diffusion and the heat generated by both the reaction and water evaporation. For a specific case, the carbonation front and temperature gradient along the reactor are analyzed. Then, the model is validated, demonstrating promising results for optimizing future carbonation processes.
