Dynamic modelling based on surface renewal theory, model validation and process analysis of rotating packed bed absorber for carbon capture

• Pioneering work applying Surface Renewal Theory to model rotating packed bed. The first dynamic distributed process for bed absorber. Dissecting physical phenomenon of mass transfer inside process. New experimental data RPB Absorber validation. Case studies absorber through both steady state and simulations. Rotating beds can reduce the equipment size costs in solvent-based carbon capture. However, difficulties are encountered when modelling due turbulent fluid flows cross-sectional area unit that changes with radius. This study aims develop a validated carry out analysis Innovatively, was developed based on surface renewal theory transfer. calculate coefficients other key variables related absorption performance. Experiments were carried new under realistic operating conditions obtained Process about effects operational such as speed, liquid-gas ratio solvent concentration performance performed benchmark MEA solvent. It found optimal is around 70 wt%. Dynamic simulation results reveal has fast responses changes. insights will promote technology towards its industrial deployment large scale capture processes.
