As the percentage of water in the solution decreases

I built up a vac/boiler from a 40 gallon water heater.

Added the option to introduce dry air (nitrogen is what I happen to have a
few tanks of) via the dip tube, to help agitate.
Right now it runs down to around 23.5" vac, and you can hear the boilin
In order to remove water content from waste fryer oils, I have been
considering a combined heat/vacuum system.
I have been wondering if a standard electric water heater vessel can
handle a vacuum of ~24" of mercury vacuum...anyone tried this yet?
The boiling point of water is around 140degF

Where does one find a vacuumpump ?

They are used regularly in garages that work on airconditioning systems
in cars, also used in home airconditioning systems, refrigerators,
freezers... They are used to remove water from the refrigerant syste

The 40 gallon electric water heater held 26" of vacuum all afternoon.
Will post details of actual dewatering soon.

Is there a table or so, where one can find at what pressures water boils ?

Rob, I think a water heater will stand the vacuum easily since it is at the
most 15 PSI compression on the steel, compared to 150 or more in tension
when in normal use. Not sure it will save energy. Vapor pressure at 140 F for
water is 150 mm Hg or equiv of 24 in vacuum but you will need

Yes, and then run it through a water separator filter or two on its way
to the engine, if you want to do a more thorough job. Our G3 SVO Max
kit uses this approach
...gravity settle only, followed by a trip through a heated filter with
two stage filtration and water separation.

Brent,
100*C is the boiling point for water. To get rid of water by the boiling
method not only do you have to expend massive amounts of energy, but the
water wil inevitably atomize and stay mixed with oil to some degree, even if
you boil the beejeebers out of it.
Your best bet is to heat the oi

Hello John
As a general rule we've found the cheaper the restaurant the worse
the WVO - more abused, cooked longer and probably hotter before being
renewed, higher FFA levels. Others say
