Seriously, I'd appreciate it if you guys could do this.

I'll chuck in $20 if it will help with shipping or something.

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

I read some post on this site and it is COOL but can you say BOOM?

700-900F is not nice I know been there when a re refinery went BOOM

Good luck to all that are into this.

bruce, when I read their stuff, I got the impression that the various iron oxides may be having a catalytic effect as well.

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.
