Characteristics of a hydro-filter pressure drop,liquid hold-up and liquid overflow rate

An experimental study of the effect of operating conditions on the characteristics of a hydro-filter (Marble bed scrubber) has been performed. There are stable operating regions of a hydro-filter with respect to the gas flow rate, the packed bed height and the height of an overflow pipe above the bed. The total pressure is mainly composed of the pressure drops in two sections, the packed section and the bubble section. The pressure drop in the packed section can be estimated from the correlation for a cocurrent gas-liquid upward flow packed bed given by Turpin ad Huntington.
