Re: [biofuel] Shelf Life / Storage / Moisture FollowUp
Does anyone know if steel tanks at ambient temps (like 250 gallon oil stove tanks) will condense moisture on the exposed walls if they are not full? Yes they do. Any vented container will do this. That's also why it is wise to fill up fuel tanks on lawn mowers and other outdoor ICE appliances after each use. Should storage of BioD incorporate a water trap? Tank on a slight incline and a simple petcock drain would suffice.

Re: [biofuel] Shelf life of BioDiesel
Don't know about Biodiesel shelf life, but i've had dinodiesel/home heating oil sit for years w/o additives and be just fine, just have to have a h2o separator as condensation will settle to the bottom over time. Found out this when i bought my home in 96, they were using propane, but had a 1/2 full 300 gal. tank of heating oil, i converted back to oil, drain some water off the bottom, about a gallons worth, and fired it up. It ran fine, and didn't add any oil to it till it was down to 75 gal. a month and and a half or so later. Jenn :-) Yahoo!

Re: [biofuel] Shelf life
Todd, I was actually asking if it's your opinion that SVO and/or WVO were immune to algae buildup. Craig Appal Energy wrote: Craig, Biodiesel can be subject to algae buildup. But it also has a considerably long shelf life when treated properly. I haven't had the occasion or need to utilize a biocide as of yet. But about the time we start storing fuel in a 100 bbl tank you can bet the problem will begin to crop up. We are considering picking up a high pressure washer that is biodiesel compatible to clean the tank prior to putting biodiesel in it. Between 1/2 and 3/4 of an inch of parafin, varnish and other junk clinging to the sides. Could use the same washer for cleaning the tanks of customers as well. The trick is how to handle the solid waste that comes off the sides. Chances are it could be adequately consumed in a used oil furnace or boiler, such as http://www.cleanburn.com/ These units also burn veg oil and come with a fuel tank pre-heater.

Re: [biofuel] Shelf life
Craig, I couldn't say they are immune. WVO would initially be more prone, as it comes in from the restaurants mixed with water from fryer cleanouts at day's end. I couldn't speak as to whether or not any particular biocide would be functional with either feedstock.

Re: [biofuel] Shelf life
Shelf life of veg oil is limitted by rancidity. Rancidity is not a limitation of biodiesel, as infernal combustion is not affected by taste. With appropriate steps taken to prevent algal buildup, biodiesel should have a tank life of years, depending upon the feedstock and air volume in the storage tank. Some feedstocks, such as linseed oil and hemp seed oil will dry under oxygenated conditions, such as an open tank or a tank with minimal fuel and high volumes of air for long periods.
