The performance of CV-S3 and 30 wt% MEA (Monoethanolamine) solvents for CO₂ capture was evaluated in terms of CO₂ loading capacity and specific reboiler duty (SRD)
Ktl : Solvent for CO₂ Captures (CV-S3)
Ktl : Solvent for CO₂ Capture (MEA 30 wt%)
Comparison of CO₂ Capture Performance : CV-S3 VS MEA 30 wt%
CO2 loading capacity
CV - S3
CO₂ loading capacity: 0.642 mol CO₂/mol Amine
MEA 30 wt%
CO₂ loading capacity: 0.483 mol CO₂/mol Amine
Specific Reboiler Duty (SRD)
CV - S3
Specific Reboiler Duty (SRD): 4.593 MJ/kg CO₂
MEA 30 wt%
Specific Reboiler Duty (SRD): 8.776 MJ/kg CO₂
※ The absolute values of specific reboiler duty (SRD) from the solvent screening system (SSS) are approximately twice as high as those in conventional carbon capture systems because CO₂ desorption in the SSS occurs in batch mode, from a fully saturated state (100%) to a fully unsaturated state (0%). In contrast, conventional systems perform continuous desorption, where the solvent never reaches full saturation or unsaturation. However, the absolute value differences between SRDs for the benchmark MEA solvent and CV - S3 solvent remain consistent in both the SSS and pilot-scale conventional systems.
