A special feed pipe arrangement, which ensures no flow of the lighter dispersed phase through the heavier continuous phase downcomer tubes, is recommended to feed the dispersed phase to the model LLE 561-LP. Similarly a special feed pipe (Model LFP 564) is also provided for the entry of the continuous heavier phase at the top of bed.
This plate is supported by a full ledge/support ring and is designed to support the packings. Tube restrictors of different sizes are used to prevent the packing from falling through the heavier phase downpipes.
This model is used when the lighter phase is dispersed (the heavier phase is continuous) and therefore, must be located at the bottom of the packed bed. It serves the twin purposes of a disperser and a support plate. Downcomer tubes allow the heavy phase to travel downward through the plate. The light phase forms a pool or a coalesced layer under the plate and orifices generate droplets. The plate design depends on interfacial surface tension, viscosity and differential densities. This plate also acts as a re-disperser and a support plate in multi-bed towers.
