[biofuel] Re: proper storage of used cooking oil to make it last longest possible
Thanks for such a practical idea; I hadn't thought of displacing the air in the tank itself. For lack of a MIG welder I could just exhaust my 1984 turbodiesel into the tank to displace the air, couldn't I? It reminds me of the old technique for ridding one's yard of gophers... Not being a chemist, I am guessing that automobile exhaust from a turbodiesel would contain more carbon monoxide than carbon dioxide, plus a bunch of soot and other particulates. Other than the temperature of the gases, would the chemical composition of the exhaust fumes degrade the oil more rapidly than the air being displaced?

Re: [biofuel] Re: proper storage of used cooking oil to make it last longest possible
It ought to take months for your oil to go rancid, considering it lasts a
week or so exposed to air at high temperatures.
Displace air with carbon dioxide - when the tank (smaller is better) is just
about full put the nozzle of a MIG gun in and press the trigger - 18 litres/
minute should go in - assuming you have turned off the welding current
(there is usually such a function for starting out a new roll of wire) and
released tension roller on the wire, then seal. Or route the exhaust of
your homebrew kit into the tank with cap on but loose, preferably via some
drier chemical. If the oil is clean and dry it should last years..-

Maud wrote. Can anyone think of something that would float on the surface of the WVO without melting? InterestingI have heard of ping pong balls being used to conserve warmth in heated swimming pools. I would like to reduce oxidation and increase storage life by covering the surface area of WVO stored in a large tank with a lot of floating objects that won't melt in the WVO...maybe ping pong balls? Styrofoam peanuts? Scraps of bubble pack? Why would floaters melt? Are you thinking of temperature melting or dissolving type melting. If temperature - is your oil stored hot or does it get hot during storage? If dissolving - I know that bio diesel can be aggressive to rubber but not VO I can't think of anything that would be solvent in VO except perhaps salts, chemical thinners and emulsion agents. It will be interesting to see if you get some more qualified responses. How long are you planning to store your WVO and have you considered a couple of other factors such as that like all 'living matter' to prolong freshness (ant oxidisation) produce should always be stored dark and cool. Would home heating oil float on the WVO or mix with it? Is there some other oil that would float on WVO? I have scavenged three home heating oil tanks that I hope to use for my future WVO Collection Coop. These 265 gallon tanks are about 5 feet long x 30 inches high x 18 inches wide. The ends are ovoid. So what this means is that a partial tank of WVO exposes a surface area of somewhat less than 5 feet by 18 inches to the air within the tank. Thoughts or ideas? But I am having difficulty visualising your tanks, if the ends are ovoid are the actual tanks cylindrical, that is to say of circular cross section or are they ovoid (egg shaped as I understand the word)? Or do you mean you have round tanks with convex ends which is the most usual liquid tank storage shape. Sorry to nit pick on terms but we all have different local ways of describing weights, forms and measures Anyway, congratulations on your scavenge. If your tanks are round, cylindrical or ovoid cylindrical and they are laying down then the area to be covered would decrease as the tanks filled and at some stage your tanks would be full of WVO and insulation whereas without insulation there would be remaining space for even more WVO. With pp balls of other granular type floating media I think oxygen would still reach the wvo surface and serve no purpose, a floating liquid sounds good - like mum used to use melted wax to float on top of her home made preserves to prevent oxidisation, but I am sorry I don't have a suggestion for WVO, ( I am sure someone here will have though :-) And having introduced an isolator the problem of how to separate it from the WVO surface when required remains. I think that if they were my tanks and I wanted to exclude oxygen I would stand the tanks on end to reduce the surface area of exposure and do some plumbing with a 1 drain at the lowest point and a filler cap at the highest. Water goes to the bottom and forms a barrier which will collect lots of gunk as your WVO settles making your pre-filter process simpler. You will still have exposure but only until your tank is full. When the time comes to empty the tank the water and gunk will drain off first and gravity will do the rest, so no pumps will be needed at that stage. The tanks should of course be elevated somewhat to facilitate draining. I would have thought that oxidisation of WVO would greatly depend upon the quality of the product, or put another way, its degree of contamination. It seems logical that adjacent to its collection it would benefit greatly by pre filtering prior to storage. On this subject though I have read a recommendation that SVO canola/rape for use as fuel should be stored from press date for at least six months and that it benefits by freezing at least once - anyone know what that's all about?
