Design approaches for the scaling‐up of multiphase flow apparatus . The scaling‐up of apparatus from the laboratory‐to the industrial‐scale is illustrated with aid of two examples. Phase partition during the flow of liquids and gases through packing layers is dealt with. It requires particular attention if the volumes of flow are different and if the efficiency of material exchange on an industrial scale referred to volume is to be the same as on a laboratory scale. A design approach for the uniform distribution of a small volume of gas in uniflow with a large volume of liquid is described. For counter‐current flow of large volumes of gas and small volumes of liquid an arrangement of packing with least possible drop in pressure is required. Some well‐known packings are compared, taking into account measured results for a novel packing referred to as “impulse packing”.
