Turbulent Flow Pump for CO₂ Capture from Combustion Emissions

In this work, we provide detailed experiments describing the behaviour of CO₂ post-combustion capture (PCC) using Monoethanolamine (MEA) solution and integration of a Turbulent Flow Pump (TFP) into the laboratory scale system. We relate the CO₂ concentration in the inlet gas flow, total mixed gas flow rate, and solvent pump speed against the CO₂ capture efficiency. CO₂ capture efficiency computed per mass transfer and thin-film theory to estimate the overall mass transfer coefficient based on the diffusion rate between gas and liquid phases. The use of TFP showed the advantages of saving space and improve process efficiency. The interconnection between studied parameters is analysed via single variable regression models to generate design equations for developing and scale-up of carbon capture systems.
