Postcombustion CO 2 separation using aqueous amine solution has a great potential to minimize CO 2 emissions but is expensive due to huge energy requirement for solvent regeneration. Several structural modifications can be implemented to minimize the regeneration energy requirement and optimize the energy efficiency. In this study, we evaluated the techno-economic benefits of three stripping modifications, namely lean vapor compression (LVC), stripper overhead exchanger (SOE), and an advanced hybrid configuration (LVCSOE) in a single flowsheet aimed at reducing the energy consumption of CO 2 separation process using 30 wt.% monoethanolamine (MEA) solution. All the configurations were simulated using Aspen Plus ® rate-based modeling, while capital investment was evaluated using Aspen Economic Analyzer ®. All the modifications reduced the energy consumption and showed economic benefit compared to the base case. The optimal configuration was LVCSOE, which reduced the energy requirement for solvent regeneration and the CO 2 capture cost by 18% and 5.3%, respectively, and can save 5.4 million USD annually. Additionally, sensitivity analysis of economic variables suggested that CO 2 capture cost is more sensitive to regeneration steam cost than any other economic parameter. Furthermore, the effect of regeneration steam cost revealed that the implementation of an advanced process configuration can result in higher net savings as compared to the base case at high fuel price.

“…The PCC plant and the CO2 compression train are modelled in Aspen Plus V7.0 (Aspen Tech, 2016). The absorber is simulated with a rate-based model which includes reaction kinetics and thermodynamic equilibrium for the CO2-H2O-MEA system, as well as mass transfer and heat transfer phenomena (Razi, Svendsen and Bolland, 2013;Sanchez Fernandez et al, 2014). The stripper column is simulated with an equilibrium model.…”

“…Some authors have proposed a purely equilibrium reaction set [20,27,32,40,52], while others have considered only one kinetic reaction between CO2 and MEA [11,[54][55][56], or multiple kinetic reactions involving CO2 and MEA and CO2 and OHions [15,35]. However, the most used approach is to consider a hybrid set that takes into account both equilibrium and kinetic reactions [7,12,16,39,41,42,49,50,[57][58][59].…”

The process analysis for the post-combustion CO2 capture using amine-based solvents is nowadays a fundamental step in its industrial scale design. In this work, the absorption-solvent regeneration system is deeply analyzed for different values of the loading in the solvent entering the absorber. The importance of the temperature and composition column profiles is highlighted for both the columns. In particular, the tight connection between the profiles and the L/G ratio is found to influence the choice of solvent flow rate for what concerns the absorber. On the other hand, an alternative configuration for the stripper is proposed together with a new criterion for the evaluation of the packing height. Finally, it is found that, in order to minimize the energy consumption in the stripper, the rich solvent must be sent at the highest possible temperature, taking into account the limitations imposed by the minimum temperature approach in the cross heat-exchanger and the solvent degradation.
