The Behavior of a Counter-Current Packed Bed Column Undergoing Flooding. The Behavior of a Counter-Current Packed Bed Column Undergoing Flooding. The Behavior of a Counter-Current Packed Bed Column Undergoing Flooding

The lecture present results of an experimental study of the hydrodynamics of a counter-current pack bed column irrigated by water and passed by air. The experimental setup developed for this purpose enables measurement of overall pressure drop, pressure profiles along the height of the packed section and the holdup of liquid retained in the packing and (if applicableú also on top of the packed section. The experiments are controlled by PC using Labview software and cover transient regime of the hydrodynamics of the column induced by variation of inlet gas and/or liquid rates. In focus of this lecture are experiments when the column under transient conditions reachers or even exceeds the flooding point
