โœฆ Synopsis

The mass transfer of oxygen between air and water in a recirculating bubble column has been studied, at gas and water superficial velocities of up to 0.23 m SK' and 0.68 m s-l respectively. Experiments show that the assumption of plug flow for the gas phase is reasonable, eliminating a possible source of error identified by other workers in calculating the mass transfer rates. The results obtained are. consistent with other published work. It is also shown that for the air-water system breaking up the gas bubbles to increase the mass transfer does not have a large effect, due to rapid recoalescence of the bubbles.

Bubble column reactors are widely used in the fields of petrochemical, biochemical, and chemical engineering processes. They are comparable to other multiphase reactors because of their simplicity, low operating costs, and higher heat and mass transfer coefficients between phases. Since a continuous
