Dear Russel Fouts,
I made enquires in S. Australia about using Frying Oil. Even as a waste =
product it would have been expensive. Restaurants in this area sell it =
to the Pig Farmers at a profit and the pig farmers make a big profit on =
the pigs because of the superior flavour of the pork fat which is =
produced. A new way to enhance the flavour so to speak.
As a kiln is being heated from cold with Waste Sump Oil the flame =
temperature is not high enough to destroy dioxins (which are created =
during internal combustion in an engine). Also, waste lube oil has a =
higher flash point and is more difficult to burn.
Filtration may remove solid contamination from Waste Sump Oil but it =
will not take out dissolved chemical components which are scavenged by =
Lithium and Zinc soaps (Presumed to be stearates and palmitates).These =
soaps do burn letting lithium and zinc corrode your refractories. I =
tried it once, noted this effect, spoke to the Chemistry lecturer at the =
Uni Campus in Whyalla and was given the griff. You would need to search =
the research papers to find out about the benefits of using an activated =
charcoal filter. A good multistage sand filter will get rid of the =
solids but not the solutes.
Hope this gives the information you were seeking.
Best regards,
Ivor Lewis.

Dear Ivor and all,
I am wondering...it used to be that fellows who dispaired to 'waste' things,
would let used Crank-case Oil set for quite a while, where it would
clearify, and sediments and layers would establish - as visually verifiable,
especially if in a glass vessel, as old 'sparklets' bottles.
They would then, when satisfied with the process, decant and reuse,
discarding the lower levels, and of course the base sediments...
I wonder to what degree the solutes may locate themselves in the lower, or
medium layers of 'settled' Oil?
Perhaps not enough, but any ideas on that?
Even if it took some months, or required some warmth, or a dash of Kerosene
for them to do so ?
It seems on principle that Specific Gravity would assert to settle
matters...or may do so the better with some small assistance...
