Incipient flooding

WebJul 11, 2015 · At incipient flooding there is high interfacial activity due to momentum transfer between gas and liquid. The intensity of interfacial activity may be further increased and hence the mass transfer coefficient, by increasing packing density. However there is a maximum packing density above which fluidised operation is impossible. WebFlooding is a common abnormal process condition wherein the distillation column stops generating a separation. This presentation will document experiments with the on-board …

What is Jet Flooding? Jet flooding occurs when the downcomers and trays consist of froth or foam, there is a quantity of entrained liquid that is lifted above the froth level on the trays of the tower. The driving force that causes this entrainment is the vapor flow through the distillation tower.
