      Re: Biodiesel Basics

    There are many here in the US, including the colder states who run straight vegetable oil. This is typically accomplished using a modification to the vehicle that allows for a 2 tank system, 1 for diesel and one for straight veggi oil. As you have mentioned, the problem has to do with viscosity at lower temps. With the modification, you start and stop the engine with diesel and use the engine heat to pre-heat the veggi oil.

    In the summer at most latitudes, this is unnecessary. At temps below the get point for the type of oil being used (each oil is slightly different) it becomes critical to pre-heat the oil

    I personally find it more cost effective to run BD since I have several engines that would require modification, and the climate is cold enough here to require the modifications. Also, making BD allows you to barter with it as few others have the modification on their machines either. For example, you may be able to convince a local farmer to combine your Canola field for you if you don’t have a combine if you give him 200% of the diesel he uses to harvest your crop…

      Re: Biodiesel Basics

    Bart, great questions.

    Water washing BD means putting a light spray of water that "runs through" the BD because water is heavier than BD. As the water falls, it collects all the water soluble contaminants that remain in the BD.

    This step is often repeated 3 – 5 times until the water that collects in the bottom is clear. If you do this with a cone bottom tank, it is very simple to add a few gallons of water to your batch of BD, let it settle off, then simply drain the bottom phase which is the was water off until you get to the BD. Then stop draining, and repeat. I personally use a misting head from a lawn sprinkler system (Toro, Rain Bird, others make this device) plumbed to a garden hose to add the water.

    Once the final wash is complete and drained, you now have clean BD with water in it. Instead of the clear liquid you would expect to put in your tank, it is milky and often the color of caramel. This is the suspended water. This is easily dried by running the tank heater, pump, and a fan to aid in maximizing the surface area of the BD and exposure to air to evaporate it off. Within a short time the BD will become light yellow and completely clear so you can see through it. I also pass my dried BD through as water block filter as it’s last step before going into the tank. I have a WIF (water in fuel) sensor in the filter of my Duramax Diesel, and it has never once given me a lick of trouble in tens of thousands of miles. The alternative is a chemical based drywash that uses beads to filter the BD after the initial separation and never adding water. I have this system, but seldom use it because the water based wash gives me feedback about my process by way of wash water contamination and I find it just as easy, and actually saves money.

    Lye is often called caustic soda, caustic potash, and other various names, but chemically it is NaOH (Sodium Hydroxide) or KOH (Potassium Hydroxide). Currently, these chemicals are fairly inexpensive in the US and contribute only a small amount to the cost of production.

    Glycerin can be used to make soap, can be used as compost, can be burned in a woodburning stove, or if you are lucky can be sold to a local soapmaker  or other industrial user of the stuff. Mine ends up in the stove as an input for heating for this and other reactions, like distillation.

     I hope this helps. On the small scale, once you get used to the whole process, BD can power the entire farm as nearly a complete replacement for petroleum. It certainly goes a long way towards helping you live off grid, if that is important to you.

    Cheers,

    Roger

    Nime,

     I started a Biodiesel thread here, in case you are still interested.

      Re: Biodiesel Basics

    Yes you can do this at home on the bench. It is how most people start.

     You will need:

    Some type of Veggi oil, Canola is good but they all work.

    Some methanol, you can get this at wal-mart or an auto parts store as "HEET" gasoline treatment, make sure you get the yellow bottle because the red one is Isopropyl.

    Some lye, which in small quantities is easly found as red devil lye, used as a drain cleaner. If you do find another brand, make sure it is 100% NaOH or KOH and there there isn’t a bunch of other helper chemicals in there.

    On the bench, we typically do 1 liter batches, so a clear 2 liter soda bottle makes a good vessel to work with. Here’s the steps:

    1.)   Heat 1 liter oil to 130 – 140 degrees F. Put it in the reaction vessel.

    2.)   Mix the Methanol and Lye. ALWAYS SLOWLY ADD THE LYE TO THE METHANOL WHILE STIRRING GENTLY. ALWAYS WEAR COMPLETE HAND, ARMS, BODY, AND FACIAL PROTECTION. NEVER BREATHE METHANOL VAPORS. NEVER ALLOW METHANOL, LYE, OR THE MIXTURE TO COME IN CONTACT WITH YOUR SKIN.

    3.)   Add the Methanol / Lye mixture to the heated oil.

    4.)   Seal and shake vigoursly for at least 2 minutes.

    5.)   Let stand for 12 hours.

    6.)   You should see 2 distinct phases in the result, the top one will be unwashed biodiesel, the bottom will be the waste product glycerine.

    In order to use this, you would need to separate out the biodiesel, wash it with water or a drywash resin, and dry the fuel. These steps are easy, and will add another day to the total processing time, but very little of it is hands on.

    Receipe:

    Oil:   1 liter

    Methanol:   .28 liter   (always 28% of volume of oil)

    Lye red devil is NaOH, not KOH, so use:  3.5 grams

     

    Hope you have fun!

    Roger

      Re: I’m scared – what can I do?

    Yoshhash,

     Everyone sees the future differently, and I hold no expectation that my ideas are always right and yours wrong. Is the soft landing you describe plausible? Yes. I, however, and as you have seen here others agree, that is not the most likely outcome here in the US.

    You might look at the result of Katrina as the most timely US example of what happens to the citizens here in the state of emergency. You can look at dozens of external examples as well, including Argentina in 2002. There are so many examples of what happens to a society when the SHTF, and typically they are not a pleasant look into the inner beauty of mankind.

    https://www.peakprosperity.com/forum/lessons-argentinas-economic-collapse-how-prepare-shtf-scenario/11780

    Ever been in a situation where a blizzard is predicted and the supermarket shelves empty in a day? This could be both worse and longer in duration than a blizzard.

    I would ask you this, assuming you have food stored in your house, have a source of heat, the water still works, and you have gas in your car, are you OK? Maybe so, but what if your neighbors don’t? Where will this lead? If you look at past examples, it can be pretty grim, and typically ends with the strong taking from the weak. Preparation for that possible outcome only seems prudent if you view it in the realm of possibilities, as I do. I hope for the best and prepare for the worst because I have a family that depends on my judgement to see them through.

     I personally find that the best way to not participate in the brutality of the worst case scenario is to avoid it and be as self reliant as possible. Even if this particular occurrence ends in a soft landing, we still have peak everything to deal with and ultimately the oil based agriculture society is doomed for failure and the non-oil based carrying capacity of the Earth must someday be dealt with. Permaculture, personal gardening and farming will be a way of life sooner or later. Bet on it.

      Re: Canary in the Coal Mine?

    http://www.reuters.com/article/marketsNews/idUSN2930278220090129

    to Lemony’s question, it appears that demand for Treasurys is decreasing both domestically and from China, Japan, OPEC, etc. I have 2 questions:

    If we reach a point where there is less demand than there are Treasurys at auction even at higher rates, is that the time to start to duck and cover? Is it the crystal ball we are watching? I like your analogy to the canary!

    If the Fed buys treasuries as mentioned in the articles, isn’t that a "false" buy in that they must print money to buy the Treasurys, and it is like loaning money to yourself? Has this ever happened before?

    Thanks in advance for the responses!

      Re: Biodiesel Basics

    The most basic BD processor is called the "appleseed" and is based on an electric 40 gallon hot water tank. You can make a basic processor for under $50 + the price of the water tank. I personally use a cone bottom tank that allows you to see the phase separation and makes it very simple to drain off the glycerin leaving only BD. These tanks come in sizes from 5 gallons all the way up to over 500 gallons. Commercial plants to batches even larger than that.

     Oil is extracted via a physical press. Some examples:

    http://www.oilpress.com/

    http://www.ayimpex.com/Oil-Press.htm

    http://www.alvanblanch.co.uk/vegetablioil.htm

    The last link has some good pics in it, including the cone bottom tanks I mentioned.

    The oil press can be diesel fueled either by using the power take off on your diesel tractor, a diesel generator powering an electric motor, or by a separate diesel engine.

    Fuel economy: there is roughly 90% as much energy in a gallon of BD as in petro diesel. That means the MPG goes down by 10%, however emissions are almost gone. It is (give or take) carbon neutral due to the farming aspect where the plants remove CO2 prior to putting it back in, and the cost per gallon ain’t bad, roughly $.70 per gallon currently.

    My pleasure.

    [quote=Worker Bee]

    Hi Nime,

      Don’t fret about the future, it won’t do any good.  The govenrment (at the highest levels only) has known this was comming for quite some time.  The CIA was well aware of the implications of Peak Oil as early as 1974.  There will be chaos in the early stages and it will get ugly, but the people who think that they can escape to the hills and live off of the land are sadly mistaken (FLIR imaging can flush out those who think they can hide).  As recently as October Northcom has been stationing troops here in the US for "disaster" assistance.  They started with 1000 troops and in January they increased it to 20,000 battle hardened troops strait from Iraq.  The trouble makers will be rounded up and sent to the FEMA detention camps and those who do comply will be reduced to a life of rations and poverty stuck in crime ridden reminants of our cities.  Stock up on canned goods, buy a few guns to protect your foodstock and be mentally prepared.  Its only a matter of time now.

     Just kidding.  The DOW will be 15,000 by October, everyone will have a new car and the weather will be sunny and 75 degrees every day.

    OK Worker Bee. I just read this thread:

    https://www.peakprosperity.com/comment/14385#comment-14385

    and you have clearly got me fooled. So what do you really think lies ahead and on what timeframe?

    Just curious

      Re: I’m scared – what can I do?

    Sounds like worker is having a bad day…

     If FEAM had any power whatsoever to pull off what you suggest, New Orleans / Katrina might be a slightly different story.

     Not every aspect of what we are going through is a conspiracy! It does have the potential to get mean, and it only makes sense to make the appropriate preparations like Arron suggests. I can only hope worker bee is only joking in the apparent suggestion that you should just give up now because the Nazis are coming.
