Metal Dual Flow Trays

Dual flow trays are sieve trays without a downcomer device. Perforations in the tray allow liquid and gas to flow through. They are mainly applied when fouling or polymerisation is expected. Dual flow trays are Suitable in highly fouling services where efficiency and turndown are not concerns.

Applications

· Fouling sections of atmospheric & vacuum column

· Beer columns, PVC slurry strippers

Benefits

· Cost competitive simple designs

· High capacity

· Excellent fouling resistance

· Dual flow trays offers relatively good mass transfer efficiency while catering to fouling application
