Data from the pilot plant was used to develop a K+/PZ absorber model in Aspen PlusRTM RateSep(TM). The Hilliard (2005) Aspen PlusRTM VLE model and the kinetics developed by Cullinane (2005) were incorporated in the model. Data-Fit was simultaneously used to reconcile pilot plant data and perform a regression of the interfacial area and heat loss parameters for the RateSep(TM) absorber model. The lean loading for the pilot plant data was shifted down by 10% to account for a discrepancy with the Cullinane vapor-liquid equilibrium data. The Data-Fit results showed that the average interfacial area for Flexipac 1Y was 80% of the value measure by the air-water column. The average interfacial area for Flexipac AQ Style 20 for 5 m K+/2.5 m PZ was 56% of the air-water measurement. The CO2 heat of absorption may not have been adequately predicted by the RateSep(TM) absorber model because the regressed values of heat loss were consistent with forced convection.Schematic of Absorption and Stripping Process for CO2 Removal...... 8 Figure 1-3 .
