Modelling of High Pressure, High Concentration Carbon Dioxide Capture in Absorption Column

Abstract:

With the depletion of low carbon dioxide (CO₂) content natural gas reserves, there is a pressing need to explore the vastly undeveloped high CO₂ content natural gas reserves and reduce the release of greenhouse gas CO₂ into environment. Our previous investigation on the absorption performance of CO₂ at high concentration level of 50% from mixture of CO₂-natural gas stream for 20wt% monoethanolamine (MEA) solution in countercurrent packed column indicated efficient removal at high pressure condition. In this present work, a combination mass transfer, chemical reaction of MEA as well as mass conservation equation was developed to model the removal behavior of the high pressure, high concentration CO₂ capture along the absorption column. The model developed in this study had satisfactorily represented the mass transfer behavior for high pressure and high CO₂ concentration gas removal along the absorption column.
