Abstract

The absorption process as taking place in a plunging jet system is investigated. Starting from the assumption that the site of the main mass transfer process is the submerged biphasic jet, a physical model is developed and a mass transfer equation is established. In the second section of the paper, a criterial correlation eqn (35): Sh* = 8.8 ( Re. We. Sc. H d N ) 1 2 for the liquid phase mass transfer coefficients in the system carbon dioxide-water is obtained, on basis of experiments in which the nozzle diameter, jet velocity, jet length through the gas phase and working temperature were varied. This equation correlates in a satisfactory manner the experimental data (the average of the absolute deviation is 14.1%).
