Still set up: 4" bubble plate with sight glass into a 3" copper column 1140mm long giving me a 15:1 ratio. This is packed with 2kg of copper scrubby. This then runs to a tee that has a 230mm double coil with a cold finger condenser. WebFeb 1, 1974 · A mechanism of flooding in packed columns based on the interaction between holdup, pressure gradient, gas and liquid flow rates is proposed here. The aim of this work is to elucidate the mechanism of flooding in packed columns, not to replace the 493 widely accepted Lobo correlations for predicting flooding flow rates.
WebPacked towers are typically operated at a gas velocity that corresponds to about 50-80% of flooding condition. This usually results in a ΔP of 0.5-1.0 in. H2 O/ft of packing. …
