Continuous Neutralization of NaOH Solution with CO 2 in an Internal‐Loop Airlift Reactor
The neutralization of NaOH with CO 2 in a continuously operated airlift reactor with gas flow rates up to 10 NL min −1 and gas phase recycle was investigated. Neutralization experiments were performed at 25 °C and the amount of absorbed CO 2 , as well as the NaOH feed rate, were recorded. The reacti...

, as well as the NaOH feed rate, were recorded. The reaction rate was calculated based on the two‐film theory and empirical equations for several parameters. The calculations of the volumetric mass transfer coefficient, the liquid phase circulation velocity, and the gas holdup were experimentally validated. The reaction rate and the process efficiency were modeled with a deviation of 5 %. |
