Foam Suppression
Foam Suppression
(OP)
I have a 20m3 sodium hydroxide soln recirc tank that generates foam like you wouldn't believe. We've tried knock down sprays but they just don't cut it.
Any ideas or experiences that may help us beat the foam?
I was thinking of using a venturi scrubber to draw the foam from the tank, destroy the bubbles and return the soln back to tank. I am not sure this will work; afraid it may just generate more foam.
Any comments would be graetly appreciated.

A 'foam reducing pack' is sometimes fitted in a 2/3 phase primary separator for oil/gas/water services to tackle this problem. This is a vane type pack that fits in the gas space in the vessel. The general idea is that the foam is 'arrested' on the vanes.
