Furnace Oil Seperate

seetle it oooout in a tank ie oil will float ontop of waaater

Or speed up that process with a centrifuge. (That's physical rather than chemical, and yet another physical process could consist of some type of filter.)

After settling and taking the water out from under it, and depending on the percentage of water remaining, add an alcohol, mix, and feed to the burner as a single-phase fluid. That way, further separation will be unneccessary.

As with some previous posts I have seen, there is not sufficient data supplied to adequately provide a solution. In this fuel oil water problem, one needs to know the viscosity of the fuel oil, the measured water content in either % or ppm, the desired water content you need in the product. We operate a waste oil refinery in Bangkok so we deal with many types of oil with water content ranging from 5-15%. We use the settling method as one person suggested. But, this handles the free water only and the waste oil still contains 3+ % water. We take the remainder out in a jacketed vessel under vacuum. We also have a Alfa-Laval centrifudge for high water content oil, but generally we try to avoid using it. It would be helpful if you stated the ppm level you need and what kind of storage you are using. There are numerous chemical treatments available as well which are easily searched on the web. As you probably already know, water reduces the heating value of the fuel oil. One way or another you should get the fuel oil under 1% water. Hope this helps
