Investigation into simulating Selective Exhaust Gas Recirculation and varying Pressurized Hot Water temperature on the performance of the Pilot-scale Advanced CO2 Capture Plant with 40 wt(%) MEA

• Selective Exhaust Gas Recirculation was simulated at the Pilot-scale Advanced CO 2 Capture Facility, Sheffield under influence of 40 wt(%) Monoethanolamine. concentrations in synthesized flue gas from 5.0 to 9.1 vol (%) mimicked. Furthermore, Pressurised Hot Water temperature for solvent regeneration inlet reboiler unit also 124 127 °C. concentration 6.6 vol(%) identified yield lowest Normalised Specific Reboiler Duty based on process and operational conditions utilized conducting test studies. Whereas 125 °C found generate Duty. Increasing partial pressure via demonstrated achieve a reduction by up about 25 %. This optimization is however envisaged increase management regime due increasing liquid-gas ratio provided capture efficiency restricted 0.9. Higher with recycle impacts cooling effect absorber (CO lean) outlet, potentially enhancing driving force absorption curtailing emission monoethanolamine. The an aqueous solution amine affects energy requirement Post-combustion (PCC) process. Therefore, this study investigates performance impact (S-EGR) MEA i.e. 10 % above benchmark Monoethanolamine (MEA) 90 its potential reduce Normalized (N-SRD) experimental research work carried out United Kingdom Carbon Storage Research Centre - Technology (UKCCSRC-PACT) National Core UK.
