Assessment of mass transfer correlations in rate-based modeling of a large-scale CO2 capture with MEA

Review on the mass transfer performance of CO2 absorption by amine-based solvents in low- and high-pressure absorption packed columns

“…A review on several mass transfer correlations in packed columns has been performed in the literature. 15, 16 Razi, et al 17 have assessed these correlations in a rate-based model for CO 2 capture with a monoethanolamine (MEA) solution to show the uncertainty associated with using correlations in large-scale CO 2 capture plants. They concluded that the interactions among the transport parameters, mass transfer coefficients, effective interfacial areas and kinetics are too complex for the mass transfer correlations to be applied with a sufficient level of condence.…”

“…They concluded that the interactions among the transport parameters, mass transfer coefficients, effective interfacial areas and kinetics are too complex for the mass transfer correlations to be applied with a sufficient level of condence. 17 So far, none of these reviews has provided a review of mass transfer performance in terms of the K GCO 2 a V parameter for CO 2 absorption into amine solutions in packed columns. In existing studies related to the K GCO 2 a V for CO 2 absorption at a laboratory scale, packed columns have been experimentally investigated for a large number of amine-based solvents across a range of operating parameters.…”

“…In an absorber packed column in a post-combustion CO 2 capture plant, the removal efficiency of CO 2 absorption by amine solutions can be determined by the gas-liquid contact degree, physicochemical properties and hydrodynamics of the absorber column, amine reactivity degree and operating parameters related to the gas and amine solution. 17 Chemical absorption of CO 2 into an amine solution can be described by the two-lm theory. 48 This theory proposes that there are two thin lms near the gas and liquid phase interfaces, which separate them from the liquid and gas bulk phases.…”

Study of the effect of condensation and evaporation of water on heat and mass transfer in CO2 absorption column

“…Sensitivity analyses of several process variables on CO2 absorption have been performed recently (Kvamsdal and Hillestad, 2012;Ralph H. Weiland and Nathan A. Hatcher, 2011;Kale et al, 2013;Razi et al, 2013aRazi et al, , 2014. Neveux et al (Neveux et al, 2013) studied the contribution of water flux to the total heat transfer flux to the liquid in both absorber and stripper.…”

Modeling and Control of Post-Combustion CO2 Capture Process Integrated with a 550MWe Supercritical Coal-fired Power Plant

“…In the scale-up design for the absorber, correlations such as mass transfer and interfacial area should be carefully selected and validated against the pilot plant data. The simulation results using different correlations were found to differ widely (Razi et al, 2014). Since the CO2 stripper is operating at a high temperature, the predictions on CO2 recovery of rate-based and equilibrium-based models were found to be similar (Tobiesen et al, 2008;Plaza et al, 2010).…”
