Packed column flooding
WebApr 11, 2024 · Unwanted foams cause column flooding and reduce separation capacities (Lieberman et al., 1989). Especially in packed columns, foam can reduce mass transfer efficiency by ~20% and packing capacity by ~30% (Chen et al., 2007, Kister, 2003). To date, there are only a few systematic studies on the effects of foaming on separation equipment. WebWhen the column was repacked with new packing, the results were essentially the same as those obtained in the inverted column. Thus, it is believed that a carefully packed column is more likely to yield flooding rates similar to those obtained in the new or inverted columns rather than rates predicted by the original correlation.

WebMay 1, 2024 · In the flooded portion of the conventional packed column, the liquid fills the voids almost completely. A steep pressure drop increase occurs across the conventional packed column under flooding. This is partly because the incoming gas must support the weight of the liquid in the flooded portion (a similar condition to a fluidised bed or a ...
