Title: Effect of solids on gas-liquid mass transfer
Issue Date: 2009
Abstract: : The effect of the solids on the mass transfer characteristics in a bubble column wasstudied experimentally for the systems air/water/Polyvinyl chloride (PVC) andair/water/glass beads. Volumetric liquid side mass transfer coefficient, kLa, was determinedunder different solid concentrations, gas flow rates and solid sizes.The presence of solids affects negatively kLa being this effect more pronounced for thelargest particles. For smaller size particles, surface properties play an important role in masstransfer as opposite effects in kLa are observed for the hydrophobic and hydrophilic particles.
