Trough Type Distributor/Redistributor with Sump

This distributor is similar to the Trough Type Distributor with Parting Box, except for the parting box, which is replaced by a sump. Feed enters the sump, which divides it proportionately to the troughs. Orifice for liquid can be located either on the base or on the wall of the troughs. Distribution points are also located at the centerline of the distributor by providing tubes in the center of the sump.

Achieving adequate sealing is critical due to a large number of joints at the sump to trough connection. All joints are gasketed for adequate sealing.
This distributor rests on a ledge/support ring. The redistributor includes riser caps and a wall wiper.

Selection criteria*:
• Column diameter > 250 mm (10 inches)
• Maximum Turndown ratio 10:1
• Liquid rates between 2-30 m³/m²hr (0.5-12.25 GPM/ft²)
• Low to medium fouling

*Selection criteria guidelines provided are typical but not limiting. Under certain conditions, special design provisions can be made for accommodating varied hydraulic and mechanical requirements.
