“…CO2 needs to be removed from flue gas streams from power plants and industries due to its high contribution to global warming. There are different technologies to address this important issue (Arias et al, 2016). Among these technologies, chemical absorption using solvents is a promising method and many studies have been performed so far (Borhani et al, 2015).…”

Rotating packed bed (RPB) absorber using monoethanolamine (MEA) as the solvent to capture CO2 is modelled at steady state condition in this study according to the first principles in gPROMS ®. The effect of eight different kinetic reaction models and five enhancement factors is examined based on the newly developed model. Selection of kinetic model has significant effect on the carbon capture level (CCL) but the effect of enhancement factor relation is not important. The steady state process model is validated against the experimental data and showed good agreement. The average absolute relative deviation for 12 case-runs is 3.5%. In addition, process analysis is performed to evaluate the effect of four factors namely rotor speed, MEA concentration in lean MEA solution, lean MEA solution temperature and lean MEA solution flow rate on CCL. Finally, orthogonal array design (OAD) method is applied to analyse the simultaneous effect of the above-mentioned factors in the CCL and motor power of RPB absorber by considering 25 scenarios. The result of using OAD revealed that rotor speed has the most important effect on CCL, and after that lean MEA solution flow rate has the second importance. In addition, the OAD method is used to find the proper combination of four factors that resulted in about 90% CCL with low motor power.

“…Different strategies have been considered and adopted by several countries aiming to reduce the CO 2 emissions, such as the improvement of energy efficiency, increasing the use of low carbon fuels or nuclear energy, renewable energy development, geo-engineering approaches and CO 2 capture and storage (CCS) (Garcés et al, 2013;Leung et al, 2014). Among these different strategies, CCS is considered crucial because it reduces the CO 2 emission from large emission sources (Arias et al, 2016;Garđarsdóttir et al, 2015;Kamarudin and Alias, 2013;Leung et al, 2014).…”

“…Chemical absorption using amine aqueous solutions is a benchmark technology for CO 2 capture (Arias et al, 2016;Bachelor and Toochinda, 2012;Kamarudin and Alias, 2013). However, it has some operational drawbacks, such as high power consumption required for solvent regeneration, equipment corrosion (Gray et al, 2005;Kamarudin and Alias, 2013), degradation/ evaporation of amines, the need of a large-volume absorber , besides additional operating costs due to substitution of solvents (Seo et al, 2014).…”

Aqueous amine solutions are benchmark solvents for CO 2 capture and their operational drawbacks are well-known. In order to overcome these problems, the support of amines on solid materials appears as an option for CO 2 capture. Cellulose is a versatile and low-cost material that can be used as a support. This study reports chemical modification of cellulose fibers extracted from rice husk with different amines and their potential for CO 2 capture. The obtained compounds were characterized by different techniques. The CO 2 sorption capacity was gravimetrically assessed in a Magnetic Suspension Balance. Quantum mechanical simulations and experimental results revealed that-NH-and-NH 2 represent major working sites of the employed compounds. The best result for CO 2 sorption was attained for the amine-modified cellulose CL-D-400 with a sorption capacity of 409 µmol CO 2 /g at 1 bar and 1091 µmol CO 2 /g at 10 bar with amine concentrations as low as 2 × 10-6 mol/mg.
