Yeah... Really...

I've been working on a processor for a few years now and it is real... You can heat used motor oil until it vaporizes and then condense it into diesel (among other things)
I am working on a plant with a foot print of about 5'x 8'x 8'tall and I should have it running very soon.

Think about this...
How much used oil is generated every day?
How much do you have to pay for it?

Yeah... I built a batch machine and it worked really well but I wanted a continuous production machine that will pump out 6-12GPH without having to babysit it... I am on version 3.0 and I have high hopes for this one... should be test firing in about a week... maybe 2 depending on weather.

Mobile_Oilguy,
can you give us some more details on how you do it ?

What sort of equipment, how much heat input, how is it heated ?

Where'd you come up with the idea ?

What sort of viscosity are you getting ?

There is a group of people around the world that are trying different designs... We have a forum dedicated to it at http://www.oiltodiesel.com
The process is actually very simple... You heat waste motor oil to about 750-1000*F and then condense the vapors at between 300-700*F and you have diesel...
As far as equipment >> We all have different ideas as to what to use but it all achieves the same result.. Our goal is to make the process and the processor simple enough and cheap enough for the average handyman to build and use.
Viscosity and color is the same as diesel/kerosene.

Most all of the oils lighter than diesel have already been extracted>> the primary objective of the oil companies is to produce gasoline and the "Motor Oil" is one of the byproducts. So if you think about it >> What you have left is Kerosene, Diesel, Lubricating oil, & Fuel oil in th motor oil you buy....Along with all the particulates that it picks up in your motor... We are just distilling out the lighter oils and leaving the heavy oils and the trash there... I have a lube business and the recyclers that picks up my oil now pays $.70 a gallon so I will even get payed for the left overs when I am done...
Another interesting thing to think about is that >> say I have to babysit my machine and it produces 10GPH (which is about what I got out of my last batch type machine) that is equivalent to making $30 per hour with todays fuel prices >> Or I could pay a guy $10 to sit there and still make or save $20 an hour >> I currently spend about $1000 a month on fuel so this would be a huge savings.

What type of fuel or power are you using to heat the temp of the oil burner? And, have you figured the cost of the heating/burner costs into your formula of the finished product? Interesting stuff.

He said he's swimming in used oil, an excellent heating fuel.

With some ingenuity he might be able to use the leftover petro product that doesn't turn into diesel.

Right now I am using a Beckett Burner like what you would find in a regular boiler or furnace and I am running it on diesel... I am going to modify it later to run on oil>>> but I want the machine running before I play around with that part... I know when I start running oil it is going to run hotter which will help production.
And No.. I haven't figured it into final product cost yet.

That is my goal >> to use a portion of the left over heavy oil to run the burner in the furnace... Shouldn't be too difficult. I will sell the rest of the left overs to my recycler which will lower the final product cost.
I am hoping that my cost will just be the electrical cost for running the burner which will be $.05 - $.25 a gallon!

There's a Wal Mart in the US with a pilot project where they're saving up the oil from their lube service, and using it to heat the place in winter.

There might be varnish buildup in your fuel system when running this stuff, since it's been exposed to very high temperatures, and might have some chemical loose ends on the molecules. Perhaps adding 5% biodiesel would keep that in solution.

If you can build a pressure vessel that can take about 400 psi with a region insulated to take 400 degrees C, and have some centrifugal pumps set up to move gases around, and have a source for some hydrogen, you could set up a cracking/hydrogenation system and put out higher quality fuel.

I am pretty much doing what is being done here... http://www.globalfinest.com/tech/
Except I don't have a plastic shredder and don't use plastics in my processor... Tell you the truth >> I think that if I filter the fuel to about 3-5 microns I shouldn't have any problems... People are running straight vegetable oil without much problem as long as the modify their delivery system to heat it... So a fuel that has the same consistence as diesel and well filtered should be a problem>>> I plan to put some lubricity additives in the fuel also.

As Far a heating systems... You can buy commercially sold heaters that run on waste motor oil and do a Very good job!... They are pretty comparable to traditional heating systems as far as initial setup costs but if you can get you fuel for free >> That is where you start to see you savings.

would you send me a sample? I'd like to put it through a GC-FID, GC-PFPD, and sulfur chemiluminescence test to see how the specs of this product really stack up to products ranging from marine gas oil to jet fuel.

Seriously... very interesting. Id love to test it from a chemistry standpoint, to see what the product really looks like chemically.

PM me if you'd like me to do this analysis.

Best,

I am redesigning and rebuilding my processor right now so I don't have any fuel to test... I will be getting back onto the plant pretty soon... I have one big project that I have to finish first before I can get back to that... I appreciate the offer though... If you want >> there is a group of people building and running these processors at http://www.oiltodiesel.com >> you could post you offer there and I am sure they would like to know the results also...

since drian oil has depending 2-5 light ends from fuel dilution
and maybe 10-25 "light" base oils at the high temp you are getting thermal cracking I would guess cost to run and odors maybe a problem.

Plus sludge disposal

Good luck to all that are into this.

Thermal cracking appears that is what these guys are doing at least 2 Concerns would be ODOR complaints from neighbors if process is large and Auto Igniton, oil @ >700F any leak WILL BURN without any help.

I guess if way ouside and in a area if On Fire not a problem then go for it.

I like stuff that can blow up, keeps you on your toes.

Working in power stations, I can agree with you (2600psi, 1000F, half ton per second evaporation rate, 130lb/sec of coal combustion).

Years ago I suggested that we should install a cracking plant in a part of the boiler that has sufficient temperature to manufacture our ignition oil ( 25,000 gal to get a unit started) from biomass/waste plastic/waste oil (we've got a fair bit of that). I was laughed at.

I think it's time to test their sense of humour again.

The boilers need diesel/light heating etc.

The main waste oil is ISO 320 gear oil.

I told them it wouldn't work !!!!

How often do you have to burn a tank of heating oil? That's a lot of money just to turn something on.

oilyriser,
we try to limit starts to two per unit per year. If we have a plant problem and it needs to come out, it's about $100k in oil to get it back in...ocasionally that ends up being a fortnight apart.

One of the stations needs oil support to bring a coal mill in or out of service. That's about 1000 gallons per mill change (two per day)

I am interested in your process for used motor oil distilled into diesel. I have several thousand gals of used motor oil a month and I would like to process this into diesel. I am current producing biodiesel at a about 500 gal. week. I would appreciate any comments and input. Thanks

Any update on your oil conversion to diesel system. I am interested. I have a large quantity of used motor oil that I would like to convert. I am also making biodiesel. I have 20 tanks at restaurants but the thief of the used cooking oil is becoming a problem.

Yeah ... when I saw that BioD from used restaurant oil was soaring in popularity and being publicized on TV >> I knew that it was just a matter of time before people were going to be fighting over every drop and restaurant owners were going to be getting a new revenue stream... Especially when oil and fuel prices spiked.
Believe it or not >> Used Motor oil is going to do the same thing eventually.... I know because I am getting paid $.80 a gallon now and they are saying that if the market sustains the price that it is at now it will continue to go up (I don't think it CAN sustain the current price but that is beside the point) They are also taking my used oil filters for no charge on top of that! I think it is because of the scrap steel prices but I just don't want to mess with them.
For converting used Motor oil to diesel we have a forum complete with picture of what we have done at http://www.oiltodiesel.com
You have to keep in mind that most of us are not experts >> Just people that are tired of getting led around by our ear and told we have to conform >>> We decided to think outside of the box and find a new and cheaper way to power our diesels with potentially free fuel...
Batch plants are pretty simple to build and there are a lot of people that have done it... I decided to build a continuous production processor which makes things a little more complicated but I am always up for a good challenge... Anyway stop by and look at what we have so far and feel free to contribute if you want.

Hi, I finished now my second refinery, this one is for continuously working. My problem is I cant get the diesel stabilizer Stabil AD 5300 and I need someone were can test my diesel.Has someone an Idee how to get to this stuff, the producer ( Nalco chemicals gives me no answer on my emails). If anyone working on a continuously refinery, you must be carefully!! The added oil has to be preheated to at least
180 C, until all water is for sure steamed out before the oil enter the system.

You're having troubles with Nalco ?

I think that they think that they are rich enough ATM. Otherwise, they'd be collecting fish heads out of your trash to find a use for.

What kind of Thermometer do you use, 700 to 1000 degrees? the auto ignition is only 750^F. When reaching those high temperatures do I need to worry about my tank blowing as long as I have no leaks, or will it not be able to reach enough pressure to worry about?
