Abstract:
For first time, bubble size distribution, bubble shape, bubble orientation, mean bubble size (d32), gas holdup and interfacial area in pure IL [BMIM][BF4] were compared with those in its binary mixtures with MEA and MeOH. Experiments were performed in small-scale cylindrical bubble column with a porous sparger using a high-speed image capture system. Further, to investigate effects of sparger pore size, column diameter, temperature and gas flow rate, experiments were performed employing gaspure IL system. Compared with pure IL, d32 in binary mixtures was smaller, which decreased with increasing MEA or MeOH concentration, whereas, gas holdup and interfacial area were increased. MeOH exhibited profound effect as compared to MEA. In gas-pure IL, sparger pore size and temperature significantly influenced on aforementioned parameters. Correlations were proposed for predicting d32 and gas holdup in pure IL for two different column sizes, which demonstrated their applicability in higher column dimensions and scaling-up.
