the mass transfer coefficient was 5.739 m/s, the enhancement effect was the most obvious.The effect of two types of tower type on the removal efficiency and the enhancement factor was compared. Results showed that the removal efficiency of dual-contact liquid-column tower under different operating conditions were far higher than that in the bubble column, but the enhancement factor was less than that of bubble column. Based on the experimental parameters of the enhanced CO2 absorption by ammonia-TiO2 nanofluid, the empirical formula of mass transfer coefficient was obtained by using the least square method:Sh=1.28023Sc1.01537 Rel1.14686... |
