Oil-in-water separation

  • #1
Try not to fly too far over my head if you answer this. I'm just an amateur chemist who spent three years in the chemistry department until I hit a wall (Calculus!) and ended up with a writing degree. So be gentle please.

I'm trying to dry oil (vegetable oil) in a process (rather than a batch). It will be in a tiny chamber, maybe as big as your fist, and it will go down at 60C, so I was thinking of pulling a vacuum on the chamber to flash off the water. The chemistry question goes like this:

If the water is emulsified in the oil, will it flash off?

I have experience building evaporative processes, as I built my own desalinator, so I'm biased to this technique. I have already figured out the kinks of it.

Any advice will help. Thanks!

To get most of the water you want to use a centrifuge first and then follow that with your method or a different drying technology as Nucleus suggests. Centrifuging is a lot cheaper than making vacuum so use it to do most of the work.
