There is not a secret that many backyard types of research, trying to build a system that would successfully process a waste motor oil into good usable diesel fuel. Many of them had created a machine of some sort that is capable of some diesel-like fuel in many cases of questionable quality.
Not many will risk filling a fuel tank of a modern car with this kind of fuel, and as a result, in most cases, this fuel is entirely for old prehistoric stationary engines that do not care about the sort of fuels they are working on.
On another hand, there are many people – “black diesel users” - who tries (some claim success) to simply process the used motor oil through the sets of filters, add some “secret”  ingredient, mix with regular diesel fuel in some proportions and use it as conventional diesel fuel.

Anyway, while people are searching for the method that will significantly lower their fuel expenses some problems involve the use of such fuel, - in some countries there are strict rules that would not allow using these kinds of processed fuels especially black diesel, some engines won’t tolerate these fuels. And despite the simple usage of the “Black diesel” one will need a set of expensive equipment; the backyard oil refining machines in most cases are massive, constructions that may be appropriate for someone who lives on farmland – not for everyone.

 

Thus the fuel that produced out of the waste oil must be clear and transparent, as real as possible. The machine as small as possible with low maintenance and capable of relatively good processing volumes, the supporting equipment with fuel treatment options must be as simple as possible yet giving the best possible results. Moreover, any person interested in home fuel production whose hands are growing from the correct place should be able to replicate the oil processing machine in a simple garage.

 

WMO continuous still

 

Sorry for a long introduction, here I want to introduce a new Continuous distillation machine (Oil Still)
That easy to work with, really small and mobile, low maintenance, yet capable of good quality diesel fuel.
The machine is relatively safe in comparison with oversized monsters where people are trying to boil gallons and gallons of oil at once - and no one wants to be next to an extremely hot system filled with hundreds of litres overheated oil.
But this particular machine made the way when the oil is stored in a separate container and continuously pumped from a distance into the reactor of the distiller, at the same time the resulting fuel and waste can also be evacuated from the distiller into the containers via the pipes that are far enough from the still. Thus the system at any present time processing just a fraction of the used oil only about 2.5 - 3L (less than one gallon) and while all safety measures must in place, the 3L of boiling oil is not 300L and even not 10L. The continuous distiller design eliminates overpressure - the reactor has a bypass, and as a result, all the reactions are happening at atmospheric pressure, while no oxygen can get into the system.

 

 

Now let’s list the materials this machine is capable of processing into the diesel fuel:
Motor oils – mineral and synthetic, automatic transmission oil of any kind, industrial mineral oils, transformer oil, hydraulic mineral oils and mixes of any listed above.
The distiller can bleach dark diesel fuels, and “red diesel.”
Currently, I put together a construction manual of a continuous distiller that help you to build a real continuous waste motor oil distiller that would be capable to continuously process used automotive and industrial oils into usable and clean diesel fuel at rates of up to 10L per hour. Moreover, the continuous distiller is capable to bleach dark and dirty diesel-based fuels and will remove the dye from the dyed diesel fuel at rates of up to 15L per hour. Thus practically supplying the owner with almost free fuel for a diesel car, diesel generator, diesel heater (burner) or agricultural machinery in your farm, all you need to do is to find a supply of used engine oil that some mechanics are having trouble to get rid off.

 

A sample of diesel fuel made out of automatic transmission oil with some absorbent at the bottom of the jar.

Thus you will own your crude oil processing mini-factory that will pay for itself in no time. Now, let’s do some calculation – the cost of the manual is yet the US $100.00
if second-hand metal from the scrap yard is using, then it could be bought from $20.00 up to $50.00

The cost of 1L of the diesel fuel in Europe is minimum $1.30, and the maximum is $1.75
Thus if you use only 20L of diesel fuel per week – you’ll spend from $1352.00 up to $1820.00
And this is less likely possible minimum; in reality, the overage car owner will double these figures at least, I am not talking about farm machinery and other possible equipment like backup power generators, water pumps, boats and so on – name it…

And at the same time, many of us can find a good source of some used automotive oil – motor oil, automatic transmission oil, hydraulic oil… at the cost of asking, some mechanics will be happy to get rid of it. Or maybe you are a motor mechanic, or own the car scrap/removal business and thinking about improving your business output and instead of having trouble to dispose of your collected sump oil – you may turn it into a useful fuel to run your yard machinery and diesel heaters, backup generators.

The distillery is a low maintenance continuous oil distillation machine that is not a pyrolysis machine - this distiller if correctly used is capable of good quality fuel that will not be prone to oxidation, will not smell horribly like a pyrolysis fuel and will ensure a standard engine work.
Anyway, even at lowest diesel fuel prices, this machine will pay for itself in no time at an overage production rate of 10L per hour it will save you at least $10.00 per hour worth of fuel – remember the crude oil prices are climbing up again so they’ll pull the cost of fuels as well!!!


The machine that described in this manual is simple and relatively easy to build by any person who can work with sheet metal and weld a bit, and the manual contains all necessary information to replicate the distiller described in these construction plans.
The plans are loaded with heaps of step by step pictures of the real working still construction, there are “how to run” and “treatment plant” videos, also some info about how to treat the homemade diesel with absorbent. The distillery is a simple continuous system, and despite the simplicity, it gives excellent results while bleaching colored diesel-based fuels, including red diesel fuel, thus the color can be removed by distillation and this process allows to avoid unpleasant sulfuric acid and triethanolamine bleaching procedure. The machine is also capable of processing pyrolysis liquids, petroleum gas condensates and capable of processing of used automotive and industrial mineral and synthetic oils into usable diesel fuel.

I will be happy to answer all your questions regarding to the continuous oil distiller.
