Interfacial Mass Transfer

Absorption rates of CO2 into aqueous solutions of sodium hydroxide were measured in shallow-bed bubble columns with sieve trays as gas distributors. Experiments were carried out in two cylindrical columns (ID 0.15 and 0.30 m) and in a rectangular unit with square cross-section 1 m2. Liquid side mass transfer coefficients (kL) and specific interfacial area (a) were evaluated from experimental data of absorption rates. The effect of bubble-bed dimensions on mass transfer characteristics is discussed and recommendations for scale-up of bubble column reactors are presented.
