Abstract
This study presents a framework for evaluating the performance of MEA-1DMA2P solution in CO₂ absorption for a structured packed bed by integrating a rate-based model with statistical optimization. The developed model is validated with experimental data. Sensitivity analysis identified mass transfer correlations as critical factors influencing CO₂ concentration profiles, with kinetic models having a less significant impact. Operating parameters showed that CO₂ removal efficiency increases with higher amine flow rate, column pressure, and amine temperature but decreases with higher CO₂ gas concentration. Efficiency notably declines when the amine temperature exceeds 333 K. Statistical optimization was used to analyze the combined influence of operating parameters on CO₂ removal performance. The response values for statistical optimization were obtained using the rate-based model, identifying the ranking of parameter impacts: amine flow rate had the most significant influence, followed by CO₂ partial pressure, blended amine temperature, and CO₂ loading of blended amine. Cost analysis was also done by scaling up the absorption system using an MEA-1DMA2P solution. The cost of CO₂ capture based on the absorber column was estimated as 40.35 $/tonne of CO₂, which is acceptable compared to the literature and other solvents and processes for CO₂ capture.
