V-Weir Distributor/Redistributor

V-Weir distributors are used when the fouling tendency of the system is high. A wide turn down range is possible due to the weirs, which permit greater flow rates as liquid head increases. With this style distributor, the liquid and the gas share the same flow area. The gas velocity through the risers usually limits the maximum flow rate of this style distributor. These distributors provide low quality of distribution compared to other distributors.

V-Weir distributors are made either in pan construction (for small columns) or deck/trough construction (for larger columns). This style distributor is clamped to or is rested on a ledge/support ring.

Selection criteria*:
• Column diameter >250 mm (10 inches)
• Maximum Turndown ratio 20:1
• Liquid rates between 2.5-100 m³/mhr (1-40 GPM/ft²)
• High 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.
