How The BioPro 190 Automated Biodiesel Processor Works
The BioPro 190 (BP-190) converts organic oils into an alternative to diesel fuel called Biodiesel through a chemical process. The common name for the process is called an acid/base catalyzation. It's just a fancy word meaning that the oil is chemically altered to allow it to run in an unmodified diesel engine.
What's unique about the BioPro 190 is that the majority of this process is done by the machine with very little user interaction. Instead of having to turn valves, meter in chemicals, and carefully monitor the machine, you just pour everything in, press a button and walk away.
Before starting the process, the user simply fills the machine with 50 gallons of filtered, dewatered oil. The oil can be any organic oil (tallow, fats, vegetable oil, etc), but in most cases, waste vegetable oil is the most commonly used feedstock to make biodiesel with due to it's wide availability.
After filling the machine with oil, the user fills the machine with a predetermined amount of catalyst and methanol. The catalyst is easily weighed and placed in the machine. The methanol is then added to the machine. The final step is to measure out the proper amount of sulfuric acid. The user then presses "The Big Green Button", waits for the mixing to start and then pours the sulfuric acid into the machine. And then, get this, THE USER WALKS AWAY allowing the machine to do it's work. There is absolutely no need to monitor the machine at all. It does the majority of it's work all by itself!
After the button is pushed and the machine is started, here's a breakdown of how the machine converts the oil feedstock into clean, crystal clear, ready to use Biodiesel.REACTION 1 - ESTERIFICATION a.k.a. the "Acid" stage
During this stage, the machine mixes sulfuric acid and a portion of the methanol into the oil. The sulfuric acid goes on the hunt for free fatty acids and modifies them so that the methanol can attach to them and create biodiesel.
Over the course of a few hours a lot of heating and mixing will occur to make sure that the acid and the methanol have had a chance to do their job. This is because a thorough Acid stage helps to make the Base stage successful.
REACTION 2 - TRANSESTERIFICATION a.k.a. the "Base" stage
This stage takes several hours to occur as well. While this stage is happening the machine is mixing the oil, chemicals, and methanol together with an extremely powerful, tri-blade impeller. This helps to really mix things together and helps ensure that all of the oil has a chance to be chemically altered.
SETTLING PERIOD - a.k.a. Glycerin Drop Out
MID POINT - DRAIN GLYCERIN
As the water falls, excess methanol and soap molecules attach to the water and fall with it, thereby cleansing the biodiesel. After the first mist wash, the water is then drained out and another mist wash is performed, only this time the big tri-blade mixing impeller comes on mixing the water and the biodiesel together to create a wonderful washing action. They call it an "agitated wash cycle" and agitate it does! It mixes the water thoroughly with the biodiesel so that it pulls the most impurities it can out of the biodiesel.
The machine then lets everything settle for a few hours, drains off the water and starts another agitated mist wash. In an effort to cleanse the biodiesel the best it can, the machine performs this last wash cycle with the massive tri-blade impeller going in full force. Once it's done the water settles to the bottom and is automatically pumped out by the machine.
And that's it! That's all there is to it. Instead of having to transfer everything around from container to container the machine does it all for you. When it's completed you can even hook up the hose to the included fuel pump and pump the finished biodiesel right into your vehicle! How's that for automation!
We hope this page has helped you see just how amazing this machine really is. We firmly believe in this product and think it's incredible! After homebrewing biodiesel for quite some time now using equipment that required a lot more work, we've fallen in love with this machine. We're sure you will too!
