Abstract

In this work we present an experiment study of solids distribution in a semi-batch slurry bubble column in the presence of foam formation. The solids concentration profiles are analyzed by means of a modification of the sedimentation-dispersion model. The effect of the presence of solids on the gas holdup is given. At the lowest gas velocity, the solids content does not affect appreciably the gas holdup in the range of concentrations considered. At intermediate and high gas velocities, an increase in solids concentration results in a decrease in gas holdup. The decrease of gas holdup with solids concentration is consistent with the trend observed in nonfoaming systems and the particle size range considered in this work.
