Figures 2.2 and 2.3 show measured adsorption equilibrium data along with corresponding fit isotherms for various tem- peratures. These demonstrate that the multi-temperature Toth isotherm describes the adsorption equilibrium well for modeling purposes. [Note the single data point in Figure 2.2 at low loading that is far removed from the fitted curve. This point is likely not accurate, with the error caused by inaccuracy in the pressure measurement or a lack of attainment of equilibrium.] Adsorption bed sizing Using a basis removal rate of 4 kg/day and a 60 min half cycle, the amount of CO2 needed to be removed per cycle was calculated to be 167 g.
