Foaming Caustic
Foaming Caustic
(OP)
I have recently had problems with caustic foaming in a 10% w/w caustic scrubber removing trace quantities of chlorine from air. The problem appears to be temperature related but I can not find any theory or data behind the phenomena to calculate the operating temperature that will prevent the formation of foam.
Any ideas ?
Thanks

I know that this is not a direct answer to your query but I thought you might want to consider the solution concentration in your investigation (if you haven't already).

The problem was solved by temporary raising temperature by steam addition. My question is regarding any relevant theory to predict at what temperature I may start foaming - a quick look in Perry & a search on the net has not given any useful answers.
