How to turn plastic waste into diesel fuel cheaply

[wheels]

Thanks to everyone.
able to find plastic bags washed and compressed. There is no organic matter in.
When recycling plastic, because it was cheaper to put into the calcite. calcite rate is close to 5% to 45%. This does not apply to all the material. Does calcite problem?
retort and other parts of the image I had previously shared. During installation I'll share new pictures. I'll be using BEK. for heather.

Sorry Kedigen, I really am not understanding your comment about Calcite. Are you adding Calcite to the Plastic inside the Retort?

Calcite is another name given to Calcium Carbonate. CaCO3. Also known as Lime. It is not acidic, it is very much the opposite, being extremely Alkaline and will react with and neutralize Acids. I am not sure if Acid neutralization inside the Retort is the best place. You would have to continually add Calcite and that would result in a lot of ash in the bottom of the retort, requiring frequent cleaning.
Any Acid neutralization should be done further along the process and the best place is in the Bubbler.

my system is running out soon. insulation bricks are made.

So how are you heating the Retort? and how will you control that heat.
Also, I can not see in your pictures, any means of heating the Reflux and other distillation vessels.

waste nylon is cheap. I tried plastic granules. Do you have tried nylon? nylon is polyethylene. nylon and plastic, while processing the second time they put into the calcite. Does this problem? please urgent information.
Thank you.

kedigen your system looking nice seems to be a good effort by fabricator

I think I told WRONG. Waste bags I'm talking about.

Yes the Plastic Bags can be used. They can be made from either PE and sometimes PP material, but there are also organic materials that make the Biodegradable Bags. They can be used OK as well.
The only negatives are the area that they take up for weight and it is best to either compact them or have them shredded. They also often are found to be quite dirty, because they tend to be used as Rubbish bags.
Sorry I don't understand your question about the Calcite.

No Nylon is not Polyethylene. It can not be used.
It is not made from Oil stock, but from Dicarboxylic Acid and Diamine. It's Molecular Groups are Carbon, Hydrogen, Nitrogen and Oxygen. In Pyrolysis, you will get a large quantity of Hydrogen Cyanide Gas from it.

Hi Friends
why there is so much silence on this wonderful discussion are all your qurries get answered please post your views and keep this wonderful discussion alive

Thanks

thanks excalibur for sharing your tests...keep it up

My new deep retort probe showed 10°C - 30°C difference compared to the existing probe.
The balance scale for determining retort level has been improved with some tweaks. This can be seen on my latest Youtube video.
I have enough diesel for 3- 4 weeks so will be running the retort with the latest tweaks soon.

OK. So I assume your PID output will switch either on or off. So how do you use that exactly?
I am upgrading from the Electric element, to a 27Kw Burner and have been trying to figure out just how to control the heat. I have some ideas, although the Burner hasn't arrived yet, so I haven't yet been able to try any of the ideas. Hence I was curious as to how you controlled your burner. Do you simply switch it on and off?
I would rather have the heat dial back rather than just switch hard off and then on again, as that is going to cause too much up and down of temperature inside the retort.
One idea I did have was to have a bypass control gate steer the Burner exhaust to flow around the retort, or slowly open and bypass the heat directly to the Flue. That way I can have greater control of the retort heat and still take heat from the burner to heat the Reflux vessel.

bypassing heat through flue may also work but then unnecessary wastage of fuel is there now answer to your question No I am not turning blower motor on and off through PID To go through my idea you must understand logic of PID . PID has two states simply say 1 & 2 as it reaches setpoint it change its state from 1 to 2 and viceversa I convert my 1140 rpm motor of blower in two speed motor having three states that means off , low speed and high speed similarly diesel supply to burner is made by modifying fish aqurium motor to two speed one . Now i get these two motors connected through PID at speed 1 and speed 2 (not zero) so when the desired temp. is gained it doesn't switch off the motor but it goes to lower speed and lower diesel supply resulting lower temp. and similarly get reversed at another set point I feel very sorrry that due to some obligations this time I cannot post any of the pictures but as soon as my 5000 kg plant gets completed I will post pictures
what type of catalyst are you using and what are the end results

retort proplem

Thanks. Wheels for answer me too. I put bags as you said but next time I try wmo and then try like excalibur retort try heating 90 percent of retort I think it is good idea..thanks

[wheels]

excalibur...today was calm very little wind so i do another test. i put lunchbags but not to much and fire gas burner in about 45 minutes reflux tempreture rise to 330 and oil begun coming out for about 30 minutes and stop then reflux tempreture begun to decrease to 204 this time i leave system fired and after a while tempreture rise again to 280 and about another 300ml oil comes out so i stop system and leave it to cool.i open retort and was empty.i only find little ash like burn paper.so as you said.vapor generated by the retort declined so this was reflected in reduced reflux temperature. but do i understand you well? is this proplem because i only heat base of retort and not 80-90% of retort? thanks

Hi Jonathan, This reply is going to start of sounding complicated with lots of numbers, but please bare with me.
Firstly, what you have seen happen is actually very normal.
You have to keep in mind just how much 400 and even 330 deg actually is and that even a small percentage of difference in temperatures results in a very large difference. For instance, if we were working in much lower temperatures, say 30 and 40 deg, then the difference between then maybe a huge 30%, but the difference is actually just 10deg. But at 300 and 400 deg, the same % but actual difference is 100 deg. So at high temperatures, small changes in anything happening inside the Retort can result in very large changes in temperature or output and so on.
Also remember that inside such a very hot Retort, if there is very little Vapor, then there is very little anything. With nothing, you have an almost perfect insulator. The only way heat can travel is via the Steel wall of the vessel, which is not very efficient. Only when Vapor is produced can heat travel again. So what you have seen is really not that abnormal. What will most likely have happened is that a crust may have formed on the surface of the little remaining plastic. Then the crust finally broke and released the remaining Vapor and that gave you another short final temperature increase.
Something else to consider is that Plastic bags trap a lot of Air. A way to help reduce that air is to stuff all the plastic bags into one plastic bag and then suck all the air out of it. The plastic bag will shrink right down and squeeze out the air from all the others. You end up with a very tight dense ball of plastic bags.
Remember that Oxygen inside is bad. Not just for risk of explosion, which actually is not that easy if most of the air has been removed anyway, but mainly in what nasties can be made. Small amounts of oxygen and temperatures over 400Deg can produce Diaoxin and cause oxidation of some of the Hydrocarbon vapors.

by controlling flow of fuel and speed of blower

OK. So I assume your PID output will switch either on or off. So how do you use that exactly?
