|DFP-644||Feed Pipe||Dispersed (light or heavy)|
|CID-744||Distributor||Continuous (heavy or light)|
The Model DSP-834 disperser/support plate serves two purposes: to support the packed bed and to disperse the light-phase into the continuous heavy-phase. Dump tubes allow the heavy-phase to travel downward through the plate. The light-phase forms a pool under the plate and the orifices generate droplets. The plate design depends on interfacial surface tension, viscosity and differential densities. This plate also acts as a re-disperser in multi-bed towers.
The Model DSP-835 disperses a heavy-phase into the continuous light-phase and in some cases supports the above packed bed. Riser tubes allow the light-phase to pass up through the plate. The heavy-phase forms a head on the top of the plate and orifices generate droplets. The plate design depends on interfacial surface tension, viscosity and differential densities.
Dispersed-Phase Feed Pipe
The Model DFP-644 feed pipe controls velocity of the dispersed phase flow onto the disperser plate. It is important to prevent excessive turbulence at the phase boundary at the plate. This feed pipe controls feed velocity and correctly positions the discharge points to minimize disturbance. If this requirement is not met, this could lead to maldistribution, loss of dispersion, and premature flooding.
Continuous-Phase Inlet Distributor
The Model CID-744 inlet distributor controls velocity of the continuous phase flow into the tower. Proper control of velocity is important to prevent excessive disturbance of the heavy/light interface, which could lead to carry-over of the dispersed phase. The maximum continuous phase flow should be less than 18.3 m3/hr/m2.
