Heavy Phase Disperser

This model is used when the heavier phase is dispersed (the lighter phase is continuous) and hence is located at the top of the packed bed. It serves the purpose of only a disperser plate and a standard packing support plate has to be used to support the packed bed. Riser tubes allow the light phase to travel upward through the plate. The heavy phase forms a pool or a coalesced layer above the plate and orifices generate droplets. The plate design depends on interfacial surface tension, viscosity and differential densities. Redisperser plates are provided in multi-bedtowers.

A special feed pipe arrangement (Model LFP 563), which ensures no flow of dispersed heavy phase through the light phase riser tubes, is recommended to feed the disperser. A special feed pipe (Model LLE 564) is also recommended for the entry of the continuous lighter phase at the bottom of the bed.

This plate is supported by a full ledge/support ring. Tube restrictors of different sizes are used to prevent the packing from passing upward through the riser pipes for the lighter phase.
