Abstract
The effect of nitrogen sparging on the rate of liquid - solid mass tra nsfer at fixed beds of Raschig rings was studied by measuring the rate of diffusion-controlled dissolution of a bed of copper Raschig rings in acidified chromate solutions. Variables studied were: ring diameter , nitrogen superficial velocity and physical properties of the solutio n. The mass transfer data were correlated by the equation.
