Abstract: Abstract This paper presents a study on the hydrodynamics and mass transfer performance of absorption of CO2 into deionized water and DEA solutions in a microreactor under elevated pressures up to 4.0 MPa. It is demonstrated that increasing gas density (system pressure) leads to increased pressure drop. Considering such effect, a modified Lockhart-Martinelli model is developed, showing good prediction over the two-phase pressure drop. For the mass transfer performance, parametric studies by varying system pressure, temperature of feeding fluids...
