Effect of gas feeding and solvent flow rate on PRB based CO2 absorption

The effect of gas feed and solvent flow rates on the performance of Al₂O₃ (I) and (II) NFs-0.01 wt.% was examined (Figure 6). It is clear that the amount of k_La increased with an increase in the gas feed/solvent flow rate, and its values were higher at high rotating speeds than lower ones. Therefore, there was a relationship between the above-mentioned operating parameters and MT performance. Figure 6a shows the performance of Al₂O₃ (I) and (II) NFs (0.01 wt.%) at high rotating speeds, a constant CO₂ content of 50 vol.%, and two constant solvent flow rates of 24 and 42 L/h based on changes to the gas flow rate through the two upper solid curves along with the upper horizontal and right vertical axes, as well as the two lower dotted lines along with the lower horizontal and left vertical axes. Figure 6b similarly shows the performance of these two NFs at the same concentration, with a CO₂ content of 50 vol.% and at the constant gas flow rates of 6, 16, and 24 L/h based on changes to the solvent flow rate. It is also shown that sovereignty was related to Al₂O₃ (II). It is possible that the microconvection strength of Al₂O₃ (II) was higher than that of Al₂O₃ (I) in the solvent.
