I have been running a lot of numbers on my new plant and I am wondering if you think it is possible to heat .01 gal to 1100F in 20 seconds running it though 70" of 1/4" steel pipe.
The pipe will be hot, of course, and if this works... then I should be running continuous 12 GPH (+/-1) if I get a 50% product from the waste oil.

I have the pipe and fitting ready to weld up and then I am going to build the heatbox. My drawing have changed a little but they are still very close to what I posted in the pictures section.

hey Oil Guy I tried to make a plant with no boiler. not much luck, but I found I could pre heat my oil to 400 by running A copper line with about 10 coils around my exhust . you do not rob any heat from your heating coils that way much easyer to get to 1100. good luck Leroy

Leroy >> When you try without a boiler... what did you use for a heat source? and how long was the oil in the fire?

I finally got all of my fttings and pipe and have started putting them together. ($300 spent so far on new materials plus the burner so $410) I wish I knew exactly what level to put the drip tray because I am a little nervous about cutting the tank... I don't want to have to redo over and over to get the right level.
I am leaning toward 1/3 of the way up the tank for the tray... What do you think? I am only going to have 1 tray... I figure that spliting the oil 2 ways will do... Heavy oils and light oils
One Idea that I had was to make 3" inserts for the tower and if the tray is too low.. I can lift it up 3" and put the spacer in. Probably a flanged insert so I can put a gasket on and bolt it all back together.

I built the nozzle so that I can easily remove and clean or replace. I am going to shot the oil in at an angle to see if starting a swirling effect will do any good.

I made a place for a temp gauge right before the oil gets to the tower to make sure that it is the right temp for vaporization. Now I just have to find a gauge that will withstand those temps. I am thinking of using a Pyrometer like on a diesel truck and inserting the thermocoupler in the fitting. I will let you know if that works.
I will install 3 temp gauges (dial type) on the tower to monitor the vapor temp while it is running.

I am building everything modular to I can disassemble very easily. The forebox and the distillation tower will be mounted with pipe unions on a platform which is attached to the feedstock tank. >> I am trying to keep the footprint as small and compact as possible.

My burner will be here on Thursday so I should be producing diesel on Sat.

I am taking pictures so don't worry.

Hey Oil Guy I will start by telling you I used a turk burner for heat. I used a small oil pump and I pumped thru about 10 ft. of 1/4 copper wrapped around the exhaust this gave me about 400 * then into a heat manifold 18 inches long with a 1 inch hole thru and a large o.d. of 2-1/2 inches. I thought the heavy wall might hold the heat well I got about 800* out . now I went into my condenser ( auto air cond.) and I got used motor oil out. I guess not enough heat ,or I should have used a tower to seperate. I will work more on this later Leroy

Yeah I am going to see if I can get it to 1100*F by using 6' of 1/4" Pipe and fittings that are looped like a spiral and putting it directly in the flame path of a beckett burner and pressure it through a 1/16" nozzle that I tested to get 1.3-1.5 Quarts per min.
at about 40psi.
It will be spraying into the bottom section of the tower.

I am also thinking of using 2-3" chimney pipe and lowering the inlet for the chimney to the bottom of the firebox to keep the heat in and not have a draft since it is forced air.

I am pretty commited to it and really think it will work.

Any feed back is helpful... Good or bad... It helps me think.

I will keep everyone posted.

OG - I have been giving your idea some thought and two things come to mind. In my home I have a re-circulating pump that keeps the hot water pumping through the hot water heater. This gives almost instant on hot water. What if we put a circulation pump to pump the oil through the grid and into an insulated holding tank?

Second thing is my truck transmission. To change the fluid in it I must get the transmission up to operating temperature before I can pump the old fluid out the oil cooler line. It has a bypass valve that blocks it from going to the cooler until it gets up to operating temperature.

So, what if we circulated the oil as mentioned above with the bypass valve preventing the oil from going to the tower until it reached 1100 deg F? Anytime the oil temp fell below 1100(Like when you supply more cold oil to insulated storage tank) the bypass valve would circulate the oil until it reached 1100 and so on. I don't know, let me know what you think?

My goal is to make it so that the spray nozzle atomizes the oil at about .5-1GPM and I am hoping to get diesel content of 50% or better. So if I use a pump that is 40psi on demand and only turns on when the pressure drops and I have enough pipe in the flame so that the temp will hit 1100 when the oil get to the spray nozzle.. then I won't need to circulate it. I really don't want the oil hanging out at 1100*F any longer than absolutly necessary. I am lengthening my pipe to get the maximum amount of oil in front of the fire to give me the right temp... The quicker I am able to reach the temp the higher the GPM I am able to Vaporize in the distillation tower.

So when the oil is ready to leave the grid it will be heated to 1100 deg? WOW, that should give you a continuous operation as long as you have oil flowing. Great idea. Is there anything I can do to help you get your plant going?

How far do you live from Mason County, TX?

Gary

[Oilguy]

I live just outside of Bryan TX... I was just contacted by a professor at Texas A&M University that has several patents under his belt and has multiple engineering degrees and wants to help me out and see if there can be a profitalbe business model that can be designed around it... I am not sure about that but if it can help to get this up and going faster then I might be interested... He has the patent on the most effecient method desalting Crude >>> I need to google that and see what the hell that means! hahaha:eek:

My goal was continuous opperation with high production and I didn't see any real way of achieving that with Verralls design with the boiler. It was flawed from the start which was hard to see given that it was drawings and not plans.

I hope that I can get this together and running very soon... possibly by this week if I get the materials I need.

OG - What do you think of making the grid out of seamless 1/4 or 1/2 inch copper tube? From what I'm told, copper will support temeratures up to 1900 degs F. Seems that would greatly reduce any possibility of leaks inside the furnance.

Gary

[Oilguy]

You are probably right and it would be a lot cheaper than what I have decided to go with. I went with 1/4" steel SCH80 seamless pipe and VERY heavy duty fittings (4000psi). I was told by welders and fabricators that it would be a lot safer this way and if the line went dry it would not melt down or sag. It might be worth trying out... definately a lot more affordable.

Yeah, that is what I am going to try. I will have a device on my furnace that will shut down the system if the temp goes past a certain point.

How much pressure are you going to run? Also, what are you using as the nozzle to spray into the tower?

Also, have you got any pics you can put up?

Gary

[Oilguy]

Working on the pics... Every time I try to use the stupid camera the battery is dead!!:confused:
I am going to run a flojet 40psi pump with a demand switch and I ended up drilling and taping the end of a brass 1/4" plug with a square head so that I could screw in a .30 welding tip... It sprays 1.3-1.4 qpm which at 50% will be about 10 GPH diesel production.
I gave the measurement to my welder to cut out some parts on a CNC Plasma machine and I should have those back on Monday... I decided to make the tower able to break apart right under the drip tray so that I can raise the tray up by adding a spacer and bolting the thing back together with gaskets to prevent any seepage.
I am also making the beckett burning adjustable so that i can move it down to reduce the direct flame on the heating grid as a temp adjustment.

I promise I will get and post pictures...

OG - Would you mind if I posted the pic of your theory for building a plant?

Gary

[OiltoDiesel]

OG - Do you think I can maintain 1100 deg F with a Beckett Burner atomizing the oil at about .5-1GPM?

Thanks - Gary

[Oilguy]

I just got my burner and I haven't tested it so see how it works... But from pictures I have seen when they are running I don't think it is going to be a problem.
And Yes... you can post the picture. I don't think it has changed much since a posted it as an attachment.
