Water removal from surfactant

Water removal from surfactant

Water removal from surfactant

(OP)
Hi all,
I have an issue which I would like to ask the experts here for some help.

What is the best way to remove the water content from a liquid surfactant? The water in concern has to be reduced from 1.0% w/w to 0.1% w/w and the current method is by dispersing the liquid into fine droplet at the vessel head space under vacuum, promoting the higher surface area for water to vapourise. In my opinion there must be another way to more effectively removing the water out.

I am suggesting to sparge some dry inert gas such as nitrogen to the liquid to strip the water out from the liquid like how nitrogen would strip oxygen out. Any idea if that will work?

Any help would be much appreciated. Cheers buddy

RE: Water removal from surfactant

Both methods will work. You have to analyze the economics to tell which is better.

RE: Water removal from surfactant

Nitrogen will work.  Sodium Sulfate might work as well.   Cooling and phase separating could work depending on the properties, Molecular sieves would probably work, 3A.
