My first plant.

[Doggieman]

Hi to all!

I finally finished my oil distiller! It is just a small plant, just to see if it would work. And it works. The "diesel" that is coming out of the condenser is still very dark so i filtered it to 5 micron just to be sure . I tested it in a Lister LD (direct injection) and it worked very well. It starts every time on this stuff. Even when its 5 degree Celsius in my shed. It can make 1.5 litres a hour (its a small plant) I just distil all the oil because I think my engine will run fine on it.

To see it in action just look on you tube and search for redkrabby. There are 2 video's on how I made diesel with this contraption.

[nikb]

nice video's, makes me want to start scavenging the bits i need to make my own

[res0wc18]

any updates?

[Doggieman]

any updates?

No...not yet. Working on a other distiller and burner. When its ready I make a new video and place that on youtube

[res0wc18]

how are you routing the feed oil? How are you cooling/condensing the vapors?

[Doggieman]

Look at the videos on you tube. Its al explained there. But in short...the oil is fed in to the boiler a little at the time by a small dosing-pump. The vapours rise up in the boiler and travel to the condenser. This is a stainless steel piece of pipe that holds a copper coil inside. Between the stainless steel pipe and the copper coil circulates cold water. This water comes from a tank that holds cold water. Cold water in...warm water out. Use a big tank that holds a lot of cooling water so the warm water that returns has time to cool down before it gets used again. The vapours condense back into liquid in the copper coil and drips into a storage container. That's it in a nut shell. Hope you understand it because English is not my native language.

You're English is better than most and i appreciate you're effort.

Is the oil fed from the bottom or top of the boiler unit?

It looks as if you have some type of sump to collect the oil that does not get converted into vapor? Is that the tank that directly under the boiler tower?

The oil is fed in from the top of the boiler. There is a piece of copper tubing sticking true the lid of the boiler. this copper tube is connected with the blue air hose that in turn is connected with the small dosing-pump. This pump doses a bit of oil at the time into the boiler.

All the oil that is pumped in, is vaporized. All that is left in the boiler is black gunk. After a few runs I clean the boiler out with a scraper.

The sump you see in the video is the sump for the burner itself. The burner is home build also and runs on waste motor oil to. So no cost to fire the burner.

The burner fires its flame in to the tower. Inside the tower is the boiler. So the boiler is surrounded with the flames from the burner. Al that you can see from the boiler is the top part on top of the tower (the lid with the heavy-duty bold)

Hope this clears things up for you.

Regards,

Doggieman.

I have a crude machine, and i'm working quite a bit on improving it. The vessel is open, no pressure. Machine is substantively improved now, but improvements are not finished for more refined and sustained testing. At maximum output on the first test, it produced in the 30-50 gallons per hour range. The resultant diesel-like oil is dirty, but cleans up well simply by settling. I'm adding a centrifuge now, which will be used to clean the hot diesel as it comes out. Also, the fuel stinks, but sodium bicarbonate added helps with this problem. The fuel runs well with no immediate problems in my 300d. I use flammable things to heat the vessel, along with a blower to completely burn the oil. As of now, I prefer not to use used oil to heat the vessel, as this would increase the cost of my fuel. I have plenty of wood and other combustibles around. Temperature control is regulated by the mass of oil in the vessel at one time, and oil is added at approximately the rate it comes out. For example, 30 gallons of used motor oil in the vessel does not change temperature radically, so this makes precise temperature control on the heating end unnecessary.

Interesting. What is the procedure to use the sodium bicarbonate? I too have considered filtering when the fuel is fresh out the machine but haven't yet. I think it might help to get the tar out before the fuel turns colors. I am currently working on a sand filtration idea. Seems to go ok, but I have gotten mixed results. Someone had posted about activated charcoal to filter which I did try. But now I am wondering about a sand and bentonite clay mix since it has absorption properties. I accidentally put some mix I used for aluminum casting and it actually worked pretty well. Further testing is required though.

I'm currently working on improving my apparatus. Once I proved that I could make dirty smelly diesel quickly, in amounts that can satisfy my driving needs easily, I find it much easier to justify extensive and further improvements.
I don't use used oil as my heating fuel, as I have plenty of other fuel (wood and other combustibles) available, and I want the most diesel out of the umo I have.
I mix some water with the baking soda (sodium bicarbonate) - just enough to make sure that there is a solution, and that the baking soda will act as a base to neutralize the weak acids in the diesel which apparently cause the foul smell. It is not necessary to add a whole lot of baking soda solution - I'm still in the testing/ experimentation stage, so I don't have exact numbers for you. When thoroughly mixed, and allowed to settle, this helps a lot with the smell issue (though I haven't entirely eliminated it.)
This week, I'm putting in a centrifuge on the collection tank, so I can do a lot of filtering just as the fuel is produced, and while it is still warm and best centrifuged. I'm thinking of adding the baking soda solution at this point, and let the centrifuge do the mixing and separating at once. The fuel will pass over the baking soda solution as it is goes through the centrifuge. I haven't tried this yet, however.
Bentonite may be a good idea, as it works very well in the wine industry (I used to be a vintner). However, one should filter or clean the resultant fuel to entirely get the bentonite out, as being a ceramic substance, it may, even in small quantities, create trouble in the fuel lines or engine. Bentonite is famous for clogging press filters in wine making, so there is a lot left after settling and decanting. Also, decanting leaves fuel behind, so I'm looking to get away from settling/ decanting, and centrifuging and filtering everything.
Personally, I think that a final press-filtration before releasing the fuel to your engine is a good idea. Press filters are expensive to buy, but I'm building one now with spare parts, and 1 micron filters are not too expensive to buy (especially if most stuff is removed beforehand anyway). Centrifuging is great, but many passes may be needed, and I don't entirely trust centrifuging to get rid of everything (perhaps I'm paranoid).
Also, in my testing, I have found that it will be very important how efficiently you get heat into your umo. If it's not efficient, it will require a lot of combustibles to get hundreds of gallons of fuel out per month.
Another couple of things:
I plan on using waste heat from the operation to heat the umo (perhaps to 200F or higher if I can) before it is sent to the vessel for thermal cracking. Simply putting copper coils above the device and circulating umo through it would do the trick. This will make combustible usage more efficient, and, allows for an additional centrifuge to be put on the umo circulating pump, for primary cleaning of the umo.
Diesel can be mixed up to 50/50 with clean motor oil with no ill effects, so it will reduce time and energy if the umo can be cleaned up enough to mix with the resultant diesel fuel. The hotter the umo is, the lower the viscosity, and the better the centrifuge will work cleaning it up. I'm going to try a 75% diesel/ 25% cleaned mo and see how it works.

so you have no liquid WMO in the bottom of your boiler to a certain level it just drips in and instantly vaporized ?

couldn't you make cleaner fuel if your stainless tower was in a upright position like a moonshine still then your copper cooling tube was warped and a external discharge tube?

you wouldn't happen to have any drawing with measurements of what you have built there that you would consider sharing ?

No...there is no liquid oil in the boiler if is its running. Your right...its instantly vaporised. I have made several designs for the cooling tower, and I always get that back diesel out of it.
The boiler that I have now can get much hotter. Maybe that is the way to go. I do not know I'm not a chemist. I did do some test with it and it seems to produce a lot more diesel in a hour of running. But its still very dark. I just do not have the time at the moment to do some more testing. I also plan to put the video of the burner and distiller on you tube. I just have to finish the last details and shoot the video.

I do not have plans or measurement. Just built this thing with the material I had lying around. I have no problems with answering questions. I anyone have them just ask. I will try to answer them. Remember that English is not my native language so there could be some spelling mistakes!

[goldhunter_2]

thank you for the answers I look forward to seeing your videos later when you have time to make them

[koluzo]

I am totally new to this 'waste oil to diesel' concept, I am indeed very interested in building a functional one but have no idea of what it's all about or how one can get very simple plans that are most importantly heap to build. Can I get help here?

[res0wc18]

you are doing well, im interested to see what all of you have made for progress in the last 4 months.

Have any of you consider using a centrifuge to filter the "black diesel" that comes out of the machine?

i use it to filter my oils

at present we always should know oil price for taking better decision and for the introduction of crude oil this is
