Mass Transfer and Influence of Physical Properties of Solutions in a Bubble Column

The absorption of CO 2 by aqueous solutions of sucrose and surfactants was studied in a bubble column under batch conditions. The volumetric mass transfer coefficients, k L a, were determined for each of the solutions and of the gas rate flow, and the experimental values were correlated with the sup...

Description
Summary:The absorption of CO 2 by aqueous solutions of sucrose and surfactants was studied in a bubble column under batch conditions. The volumetric mass transfer coefficients, k L a, were determined for each of the solutions and of the gas rate flow, and the experimental values were correlated with the superficial gas velocity and the physical properties of the liquid phase. The proposed equation reproduces the experimental k L a with an error of less than 10%.
