An experimental study of the effect of operating conditions on the performance of a hydro‐filter (marble‐bed scrubber) has been conducted. The overall volumetric mass transfer coefficient, K G a , remains constant while the gas flow rate changes in the stable operating regions but increases sharply in the region above the loading point, corresponding to a sharp increase in the total pressure drop of the hydro‐filter. Since the gas flow is turbulent and the liquid flow is laminar under the present experimental conditions, the value of K G a is strongly dependent on the flow conditions of the liquid and its properties, while those of the gas have less effect. The performance of a hydro‐filter as a mass transfer device is shown to be superior to other types of scrubbers although its main drawback is large pressure drop.
