Hello fellow OilCrackers! Some ideas and questions.

[ShaferLabs]

Hello fellow OilCrackers! I just found this site yesterday, and am very impressed with your work. I have been thinking, drawing, searching and reading for about a year now on this subject. Please don't take the following wrong, They are just questions, and I've never done this myself!

The systems that (Oilguy) built look like they would have a few more problems than just being the hottest thing under the Texas sun! Mainly I'm wondering how you keep the condensing tower at the correct heat to crack as completely as possible? Just spraying 700+ degree oil in there works? Do you get a complete crack or are you getting a mixture of heavy oils and napthas that just have the consistency of diesel when mixed? From what I understand, you are cracking in the heating tube, anything not cracked goes into the waste barrel instead of being re-processed. and much of it could be over cracked. You are not using the condensing tower to crack because of coke buildup? Could that possibly be because the temperature was not regulated well enough in your previous design?

What I have come up with is kind of a hybrid unit. The diesel is not condensed in the tower, but in the tube that leaves the tower. Anything anything not cracked down enough will not make it out the tube. This design relies on keeping the whole tower at the correct heat: Hot enough at the top so the diesel will not condense and run back down to be re-cracked - we don't want gasoline. And cool enough so the long HC chains don't get to the top in vapor form - we want them to condense in the tower and be re-cracked. The burner uses the crud that would otherwise build up in the bottom of the unit. We try to keep the time the raw stream is in the heated tube to a minimum so we don't crack already short chains down further.

I've never done this myself, and up until yesterday, did not know that anyone else was! This site is a great find. I have built 3 large biodiesel processors, and currently own a 300 gallon fully automatic processor, washer and dryer that is not quite finished. I have been running 100% used engine oil in my truck for a long time, and if I could turn it into real diesel that would be great! Not all trucks will tolerate 100% used oil. Mine is a F350 with a 471 Detroit Diesel and 1/2" fuel lines!

Following is a drawing of what would be, to my current understanding, the best small scale thermal cracker. Please let me know what you all think of this, any improvements, design flaws etc! BTW, have you seen patent No. 5885444?

Regards,

Lawrence Shafer

Fire away.... Don't worry about offending anyone here... we are called crazy all the time so we have thick skin... :D

Your right... I have found a number of problems with my design... in fact I posted my design so that I could get positive and negative feedback to improve and refine the design before I get too far in building it... Right now My main problem is not having enough heat to the cracker.... I think when I find out how Leroysoil build his heavy oil burner... it will lead me to a solution to my problem....
As for the condensing tower... It will eventually be insulated and wrapped to keep a consistent product but I am not too worried about burning a cocktail mix that is thinner than the motor oil that we are cracking... :) especially if we cut it with pump diesel.

Just spraying 700+ degree oil in there works? Do you get a complete crack or are you getting a mixture of heavy oils and napthas that just have the consistency of diesel when mixed?

Yes... it has been working when I ran it... but I had other issue to workout before I got to fixing that one. and No... at this time I am not getting a complete crack due to a lack of heat....


From what I understand, you are cracking in the heating tube, anything not cracked goes into the waste barrel instead of being re-processed. and much of it could be over cracked.
Yes... but I am rethinking how I am cracking the oil... I end up with too much back pressure in the tubing and still don't seem to have it hot enough... I am thinking of going with a much larger cracking chamber (5" pipe with maybe 1" of oil in it directly in front of the heat source.) >>> I have it sketched up but on paper right now... I will post it on here when I have a better idea of what I want....
Also.... I am going to have the unprocessed/ uncrack oil run back to the main tank with a valve that I can divert to a waste tank when I think it has been fully processed. (again... still rethinking this part too)

You are not using the condensing tower to crack because of coke buildup? Could that possibly be because the temperature was not regulated well enough in your previous design?
I haven't had any buildup on my new plant... but I haven't run it very long at all... so there should be any yet.... Also we have all had problems regulating the temp because the fire is either on or off... so there is a huge fluctuations in the furnace... that makes it hard to stay consistent.

The burner uses the crud that would otherwise build up in the bottom of the unit. We try to keep the time the raw stream is in the heated tube to a minimum so we don't crack already short chains down further.

That is an interesting concept... What size tubing are you thinking of for the outlet and how long before you get to the holding tank?
I have a couple of other questions... but I will start there.

Hahahaha.... 1/2" line? Wow! No smoke? or build up? How well are you filtering it?

I have seen lots of drawings... I will look that one up and see what it looks like... I noticed that you have a lot of bubbler/drip plates....
What is the purpose of these if you only have one outlet?
What kind of pump are you thinking of using to run the unit?
Do you currently have a Beckett that will run on used motor oil?
Is the flapper used as a thermostat to divert the exhaust heat?
Any Idea on physical size of your unit?

I actually had a drawing that is very similar to this >>> I will have to go to my note as to why I chose the one I did... I had about 5-10 concept running at the same time and was talking to a couple of engineers a Texas A&M to get feedback on design issues.... Unfortunately a lot of that correspondence was in my email box before my computer crashed and I lost all of that... :(

Glad you found us... I hope we can get something working that doesn't require a baby sitter and has good production rates.

Good! me too!

Right now My main problem is not having enough heat to the cracker.... I think when I find out how Leroysoil build his heavy oil burner... it will lead me to a solution to my problem....
I have a burner in the works made from a large injector pump and injectors. The problem I have is they are direct injection injectors, and I need IDI injectors so the tips will not plug. It has a 1750 RPM electric motor driving the pump, and I have a servo on the throttle for flame control. I think it may be the answer for LARGE flame burners!


As for the condensing tower... It will eventually be insulated and wrapped to keep a consistent product but I am not too worried about burning a cocktail mix that is thinner than the motor oil that we are cracking... :) especially if we cut it with pump diesel.
Part of my design revolves around being able to heat the tower without running 50 gals of fuel through it.

It is my sense that if you pull the oil off the bottom of the puddle in the tower to run for heat, it will keep the uncrackable stuff out of there automatically.

I haven't had any buildup on my new plant... but I haven't run it very long at all... so there should be any yet.... Also we have all had problems regulating the temp because the fire is either on or off... so there is a huge fluctuations in the furnace... that makes it hard to stay consistent.
See my big IP pump idea above.





That is an interesting concept... What size tubing are you thinking of for the outlet and how long before you get to the holding tank?
I have a couple of other questions... but I will start there.
Maybe 5/8 soft copper?



Hahahaha.... 1/2" line? Wow! No smoke? or build up? How well are you filtering it?
Yup, 1/2" truck air brake line for the fuel line. No smoke, no build up! 5 micron luberfiner 750 bypass engine oil filtration system off semi truck.



I have seen lots of drawings... I will look that one up and see what it looks like... I noticed that you have a lot of bubbler/drip plates....
What is the purpose of these if you only have one outlet?
Just an idea to keep the heat down and the cool up...

What kind of pump are you thinking of using to run the unit?
Probably very small hydraulic power pack

Do you currently have a Beckett that will run on used motor oil?
No

Is the flapper used as a thermostat to divert the exhaust heat?
Yes, the flapper will be computer controlled along with the IP pump burner servo to keep both the bottom of the cracker and the top at the correct temperature.

Any Idea on physical size of your unit?
I'd like to build one 12" dia X 14' high, but my first on might be on the kitchen stove!

A very nice heavy equipment friend GAVE me a new 12"x14' by 1/4" wall pipe today. So I guess I'm starting in full size! Kinda scary, but I'll do my best!

Post lots of pictures! I am interested in your progress as well...

[ShaferLabs]

I will post lots of pictures! So you think I'm on the right track as far as you understand this process? Should I advance with this design?

Thanks,

[Oilguy]

As far a the tower.... the only thing that I am concerned about is it being too big and you not having enough heat to keep it 700+ for as long as you want without being 1000-1100*F in the furnace with a lot of BTU's to spare.... But that is mainly because I haven't seen you burner design specs...
I do like you idea though....
How big is your heating coil going to be? Linear length? Tubing diameter? Material? and Pump pressure?
What size exhaust are you going to have?
OG

[Oilguy]

I have a burner in the works made from a large injector pump and injectors. The problem I have is they are direct injection injectors, and I need IDI injectors so the tips will not plug. It has a 1750 RPM electric motor driving the pump, and I have a servo on the throttle for flame control. I think it may be the answer for LARGE flame burners!
I like the idea for how to adjust the temp by using the throttle control the adjust the flame/heat.... Do you know how to build this kind of burner or are you experimenting?

Part of my design revolves around being able to heat the tower without running 50 gals of fuel through it.
That is going to have a lot to do with design... I had a 8-10' chimney stack on my last plant and was only getting 400*F at the tip and I know I was over 1000*F in the furnace... there is a lot of heat lost in the tower so you are going to have to insulate the poo out of it to maintain the heat level... what are you thinking for insulation? I used Vermiculite in my last processor to insulate the boiler and it worked very well>> I could place my hand on the out side of the boiler area and it was only about 150-175*F with 4" of insulation. >> However if you don't have the area you want insulated sealed up really well it will be a really messy ordeal. It is like trying to hold a pound of sugar in your hands.... :)

It is my sense that if you pull the oil off the bottom of the puddle in the tower to run for heat, it will keep the uncrackable stuff out of there automatically.
That would be the way I would like to run the burner >>> YOu need a way to cool the oil before taking it through any parts that have nylon, teflon, plastic, soldier, in them.... Do you have a plan for this?


Maybe 5/8 soft copper?
That will probably work... I was running 3/4" Galvanized in my last unit and it was gushing out of there.

I need to post my latest design so I can get some feed back... I have been lazy lately because it is heating up here in Texas.

[ShaferLabs]

I like the idea for how to adjust the temp by using the throttle control the adjust the flame/heat.... Do you know how to build this kind of burner or are you experimenting?

Just experimenting. It should put out about 1,530,000 BTU/hr. I calculated that from the HP the engine would put out at full throttle not taking into account wast heat from the engine, so it will prob be more yet! I'm not sure how that compares to your burners, but I'd guess it's a lot more.

That is going to have a lot to do with design... I had a 8-10' chimney stack on my last plant and was only getting 400*F at the tip and I know I was over 1000*F in the furnace... there is a lot of heat lost in the tower so you are going to have to insulate the poo out of it to maintain the heat level... what are you thinking for insulation?

I'm thinking of using kaowool, it's some amazing stuff.


That would be the way I would like to run the burner >>> YOu need a way to cool the oil before taking it through any parts that have nylon, teflon, plastic, soldier, in them.... Do you have a plan for this?
The bosch pump I have should be able to stand 200 degree oil. So I'll probably just use a length of soft copper here again.


Maybe 5/8 soft copper?
That will probably work... I was running 3/4" Galvanized in my last unit and it was gushing out of there.
Vapor or solid fuel gushing out? If you were putting out that much maybe I should go with a smaller unit? I want to make about 1000 gal/week. I have a source for that much oil, and he would like to buy about 700 gal of fuel a week from me. He's the same guy that gave me the pipe. He works on the railroad and has access to almost anything.

I need to post my latest design so I can get some feed back... I have been lazy lately because it is heating up here in Texas.Do it! I'd love to see it and give some feedback.

Just letting y'all know I'm still around! I expect to be running in about six weeks. I have the plant about half done. I should post some pix. I also have a design for a super hot and clean oil burner, often used in forging, Very simple to make. Anyway, I'm still here!

Lets see some pictures of your progress.... I wanna see how you are building your tower especially...
OG

[Oilguy]

I was poking around the net the other day and ran a across a back yard foundry site,,, The guy was using waste motor oil to run his burner and was getting fantastic results...
Here is the site
http://www.backyardmetalcasting.com/oilburners05.html
He is on his 6th (I think) version of burner and he is using a oil injection style with a propane starter... I have been thinking about this style and haw I could control it... It seems that it would be fairly easy to control the temp in the furnace by controlling the amount of oil going through the injector. I am figureing that I have about 6 more weeks of intense heat here in Texas and I will be able to get back out there for more than an hour at a time... SO I have been thinking about the project...
I DID build an air conditioned room in my shop for some smaller projects and the nice thing about my processor is that I originally made it modular! SO I can probably work on it like that as soon as I finish up the project that I built the room for.

Anyone still out there?? Has anyone given up yet?? Anyone interested in getting started??
Lets hear it!

Still here OG and watching what you're doing. I bought the appleseed biodiesel brewer plans. It's pretty simple, straight forward, and quite detailed. It just takes time, money, and desire. Unfortunately I rarely have all three at the same time. :D

I hear ya! Desire is lacking for me a lot of times too... hahaha... Well I have some new drawings in from of me now... I am thinking about it again... So you never know.
I wish I had a qualified helper here that I could tell what to do and get back to me when it was done... BUT.. Those cost too much money.
:D :D

I'm still watching too and working on the shop. First things first. The Dodge smokes some at an idle but otherwise burns the transformer oil fine so more time is bought.

I run wvo in my diesel generator. I am at a remote location in central British Columbia and it would cost $40,000 to bring power in from the road. Besides, it is way more fun doing it myself.

Anyway, with wvo, there are two routes to take, heat the vegetable oil to 170 degrees as it enters the injectors, or make biodiesel. Fora stationery application, heating the oil is way simpler. Using the hot water from the diesel, I built a heat converter out of 2" black pipe, which I drop into the oil, and it heats up the oil to about 110 degrees, then it goes through a 'vormax' filter that also uses hot water from the gennie to heat it more and then through a unit called a 'vegemax' which is just a 12" section of 3/8 pipe that uses the 12v battery to heat it even more and presto, it enters the engine at the right temp.

Been running it this way for 6 weeks and it seems to work like a charm. The next step, is to begin mixing cleaned up wmo into the wvo, since I generally have better access to free wmo. I have a centrfuge, but the diaphragm on the pump went (pumped hot rad water through it, ooops!) and will use that to clean up the oil. And then start mixing, beginning at 5%. I run a kubota 1903 engine (the gennie can crank out 15 kw) and am wondering how much wmo it will tolerate before I start screwing up the injectors and/or c arboning up the valves. Anyway, the idea is to then ramp it up to 10%, 15%, 20%. etc. Those with experience burning wmo in a diesel, would appreciate your feedback, as to the tell tale4 signs that I am at the right number for my partiicular diesel engine. It seems like there is wide variance as to which diesels will tolerate how much wmo.

This will give me time to figure out which way to go with cracking the wmo.

Cheers!

Shaferlabs,

I am following your project with great interest to see how you make out! I am definitely going to build something here, but probably it would be a good idea to figure out what the hell I am doing first.

Thank you for sharing, your ideas look great!

[ShaferLabs]

I'm finishing the tower today. I know I'm way to painfully slow for all you watching, but things are kicking in gear on this now! I'll post some pictures this evening. My camera is down at the shop so I cant do it now. See ya this evening!

BTW, Even though it looks like it, I'm not forgetting you guys!

Lawrence

[bn37]

Thanks for posting! I'm anxious to see your handy work. :)

[ShaferLabs]

Here are a few photos, The tower is almost finished. I have a 4'x10' piece of 22ga stainless to wrap around the tower spaced 1 inch out (with the ring on the top and bottem and the spiral spacers.) with KaoWool on the outside of that and then galvanized sheet. The hot exhaust from the burner gets run through between the pipe and the stainless to help heat it. I have everything, it's just a matter of getting it done.

Price so far.
Pipe. $380
Steel for firebox and misc. $270
22 ga Stainless sheet. $160!!!
26 ga galv sheet $30
KaoWool $320
1/2 soft Copper tube $140
Thermocouples $40 ea (3)
Microcontroller, LCD, Keypad, Servo motors, PWM Blower control, etc $270
I need an electronic variable fuel pressure regulator now.
Pumps $230

and prices at the pump going up, up, up!

There is another ring on the top end not shown. The pipe is 12" gas pipeline from Boone Express in Nashville (I service all their trucks) 12' long. It's gonna make 80 GPH of pure EN590 Diesel Fuel per hour form oil and plastics!!! Is this a pipe dream or what?!!

[moparguy]

Looking GOOD. Very nice work.

Are those bt4 blocks in the background?

Thanks for the update.

RJR

No, those are aluminum 4-71 Detroit blocks, My favorite pickup engine! I do have two good running 4bt's and a 6bt sitting here though.

[ShaferLabs]

Just a funny side question, Is there a direction that air would rather spiral going up a stack in the northern hemisphere? Hope I'm not working against nature here :)

[bent wrench]

I'm thinking the air will follow the guides regaurdless. but to check go flush the commode.

[ShaferLabs]

Another few days work to show! I have the stainless wrapped and screwed about halfway up. I'm screwing every 2". I didn't get photos of that part because it got too dark. Here are a few pics. I can't wait for fuel to come streaming out the little copper cooler pipe, and heat waves to come out the stack!!!

http://www.diesel.shaferlabs.com/drilling.jpg
OK, so this is not as easy as plasma cutting and I had to complain about it!

http://www.diesel.shaferlabs.com/setting_stack.jpg
Just got the stack in the hole.

http://www.diesel.shaferlabs.com/bolted_down.jpg
She's bolted down (I spent $103 on grade 8 bolts today)

http://www.diesel.shaferlabs.com/wrapping_stainless.jpg
Struggling to get the stainless under control, I ended up with 7 straps on the thing!

Tomorrow I'll wrap the KaoWool around the stainless, and then wrap some 26 ga galv sheeting around that. The firebox also get KaoWool and firebrick. Then the 7" stovepipe gets put up on the back of the machine and plumbed into the stainless. I figured I'd bolt a plate onto the top of the stack and seal it with stove gasket and cement. The only problem is I'd like it to blow off at about 20 psi (just in case) so I don't have too big a bomb here. How many GPH do you think I can produce? More tomorrow perhaps.

[bent wrench]

Gets dark to early now but we are reading. and very interested to see it work.

[bn37]

I'd bet most of us still come around frequently. Personally I've been going crazy busy with work, but still check in all the time.

[rovingbenz]

I check every day too. Just no shop to work in yet.
Ryan

[i_stripe]

I following your progress also. I check in several times a week. Just not much going on at my end right now.

[ShaferLabs]

Where has OG gone these days? I tried to PM him and no luck.

[Oilguy]

I am still alive...
I am building a 20x40 swimming pool in my back yard... It is a huge project and I have to get it finished before I get any more rain.... Should be done by next weekend and I am definitely motivated to get the processor going since diesel here is around $3.20+
I am glad to see we have plenty of people checking in... I hope others will get interested and decide to participate and build one...

Oilguy

[ShaferLabs]

Good to see you still around! Maybe I'll get more done tomorrow if it'll quit raining...

[Oilguy]

You done yet?

hehehe....
:D

[ShaferLabs]

You done yet?

hehehe....
:D

Now way:D Are you done with your pool yet???:p

...and then you still have to get to work on YOUR processor...

[Oilguy]

Now way:D Are you done with your pool yet???:p

...and then you still have to get to work on YOUR processor...

Hahahaha.... Almost...
I just finished the concrete work inside of it... Now I need to finish the tile work and paint it and the pool will be done.... I am figuring about 5-7 days
(weather and less sunlight has really been slowing me down!!!)

I will post some pictures of the progression if your interested....

OG

[ShaferLabs]

It doesn't show, but I have three more days of work done on it! I have the power and water run to it, the microprocessor, thermocouples, and giant servos are sitting on my desk, and the insulation is done. Oh and I have $200 worth of pipe fittings sitting here...

Here's a pic of my youngest brother, my dad, and I, doing insulation:D
