Flooding velocity in packed column
WebIn this work, the upper limit of operating regions, which corresponds with the flooding velocity in the countercurrent contactor of col umn type, will be compared with each column (packed column, wetted wall column, bubble cap column, perforated plate column. and turbo grid column). Weba percentage of the flooding velocity, is implemented to select operating gas velocities when sizing packed columns and to avoid detrimental effects on absorption efficacy. In order to prevent the operation of packed columns from flooding, various
