  • Making a large batch of biodiesel (video)

    In these four videos, you'll see how to set up a small-scale biodiesel production facility. They feature Graydon Blair of Utah Biodiesel Supply.

    This is part 5 in the series. <- Previous

    Discuss biodiesel production in our biodiesel production forum.

    Making A Large Batch - Shop Intro & Filtering Oil (08:30)
    This video highlights how you can set up a basic small scale Biodiesel production facility. We introduce you to some of the basic components you'll need to produce Biodiesel. In particular, we show how to filter oil, how to transfer oil around in a shop, how we store and transfer methanol, introduce the catalyst and more. We also discuss a bit about which diesels can handle Biodiesel.

    Loading Oil, Catalyst, & Methanol (05:35)
    Using a BioPro 380, we introduce how easy Biodiesel can be made. We show how to load the machine with oil using an inexpensive sump pump, how to add the methanol, how to measure out the catalyst & get ready to start the batch. There are several different styles and kinds of Biodiesel production equipment available on the market, this one just happens to be our personal favorite.

    Making A Large Batch - Starting The Batch (02:24)
    Using the same BioPro 380, we show how to start the machine and get a batch running. This one's pretty small because it really doesn't take much to get it going. Reach around back, turn the machine on, and push the start button. We then load it with sulfuric acid (to give us higher yields) and then we let the machine take care of the rest.

    Making A Large Batch - Transferring Finished Fuel (06:19)
    This video wraps up our videos on making a large batch of Biodiesel. Using a BioPro 190, we transfer finished fuel from the machine into our storage barrels. We also give a basic overview of the BioPro machines, discuss the differences in the machines, and then wrap it up.

  • Titrating oil for biodiesel (video)

    In these four videos, you'll see how to titrate your oil to determine the acidity of the oil before converting it into biodiesel. They feature Graydon Blair of Utah Biodiesel Supply.

    This is part 3 in the series. <-Previous | Next->

    Discuss biodiesel production in our biodiesel production forum.

    Titrating Oil - Building A Titration Kit (04:11)
    In this video we show how to build a basic titration kit that will be used to titrate oil with. Titration is nothing nore than a method used to find out what the acid level is in the oil that will be used to produce Biodiesel. It's necessary to know this because it will indicate how much catalyst will be used to make biodiesel.

    Titrating Oil - The Chemistry (05:04)
    This video explains the chemistry behind how a titration works. We explain what a titration will indicate and why it's important to perform them on used oil. Don't worry, like the other video's we keep this one simple. No chemistry degree needed.

    Titrating Oil - Preparing Titration Solution (04:31)
    This video shows how to prepare the titration solution that will be used to do the actual titration with. It's important that this be done accurately because it will impact the titration readings. To make it, add 1 gram of catalyst (either Potassium Hydroxide (KOH) or Sodium Hydroxide (NaOH) to 1 liter of water.

    Titrating Oil - The Actual Titration (10:54)
    This is where it all comes together. We do 3 complete titrations from start to finish. We measure everything out, explain how to mix everything, do the actual titrations, and then explain what the results mean.


    The Basic Titration Method
    1- Add 1 mL of Oil to 10 mL of Isopropyl Alcohol
    2- Add a couple drops of indicator solution (Phenolphthalein is what we used)
    3- Start adding measured amounts of Titration Solution
    4- Watch for the color change to stay for 30 seconds
    5- Record how much titration solution was used
    Titration Solution Used = Number Of Grams Of Catalyst To Use Per Liter Of Oil
    If there were 4mL used, then 7.5 + 4 = 11.5 grams X 100 liters of oil = 1150 grams of KOH
