The axial mixing characteristics of a pilot-scale multi-stage mechanically-agitated gas/liquid contactor (the PROCHEM column) was investigated over a wide range of design and operating conditions. The experimental results, obtained using the dynamic response method, were analyzed using three models. The tanks in series model were identified as the one most suitable for describing the axial mixing in this type of column and a general correlation describing the effect of various design and operating conditions on the axial mixing characteristics was developed. A comparison with other multi-phase column contactors indicates that the axial mixing characteristics of this column are superior to those of unagitated bubble columns operating under similar conditions. Means for further improvement in column performance were also identified.
