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.
