How to turn plastic waste into diesel fuel cheaply

[Kris3033]

Congrats

Dear all,
Congrats to all !!!
Today completed my first trial n succeeded in producing about a liter of diesel.
The color of my diesel is light pale yellow. It burned almost like Diesel and Petrol with initially bluish flame than bluish yellow flame. I am so excited.
Thanks to all for their support n guidance. Special thanks to Jeti (Big Dady) and Asad.
Soon I will load the pics of my setup and Diesel.
I was just able to reach the temperature of about 250 C.
Initially Oil started to come at Temp of about 175 C drop by drop but as temp rise oil flow increased.
I know the future for this is very bright.
I once again thanks to all guys for there support and well wishes.

Congratulations Kris3033
You seem very happy, that is fantastic.
Waiting for your pictures setup

congratulation


Hi Kriss3033
Congratulations Kris3033! Looks like you have made petrol
But I note you in products have got gasoline, diesel .through your test
I saw “The color of my diesel is light pale yellow. It burned almost like Diesel and Petrol”
You can announce your affiliate data feed formulas materials input reactor
The finished product is how many liters of petrol
I suggest you should fractionating condensation will be fine diesel, and gasoline

Hi Rahal,
please read through all this topic, it has already been discussed multiple times and I hate to repeat myself, well, actually I am just lazy. The short version is - no need for any gasses, why? Read the topic and find out. It is really very much advisable to read all the posts through as most of your questions are already answered.

congnghiah4,
I got aboyt 750mL of fuel from 1 liter of shredded PE. But one liter of shredded plastic weights also about 750 grams, so the efficiency is even better. Don't confuse grams with mililiters. The 750 mL of fuel actually weights around 500mL or something like that. You lose mass in the process, but gain volume due to reduced material density.
Thanks,
Jetijs

Hi Jetijs,
I am new here and have been reading over the forums. Your knowledge is amazing! I have a question for you. I read where you said pvc wasn't a good choice. I am able to access about 15 tons of pvc a month for about one dollar a ton. It's the only plastic that I have reasonable access to, because of my location. Now my question--Is pvc feasible for fuel at all if I use a modified bubbler to filter out the chlorinated product? I apologize if you have addressed this already and I missed it.

Pvc

Hi Jetijs,

Hello ;
PVC cannot be used alone as a feedstock for producing liquid fuels .
Even big companies selling there plants for 3-4 million dollars says specifically not to include PVC in the feedstock .

PVC Decomposition :
Polyvinyl chloride gave hydrogen chloride as by far the main gas. The C–Cl bond in the PVC structure has a lower bond energy than other bonds in its structure and upon heating has a tendency to break first. As a consequence, PVC thermal degradation begins around 150◦C which is a much lower temperature than the other common plastics. The intermolecular chain transfer reaction which follows leads to dehydrochlorination and
hydrogen chloride is produced.

Thanks, Asad!

I will look for other feedstock sources!

This is really impressive, so if we run out of oil we can extract fuel out of the remaining plastics. Won't this worsen our exhaust problem? This will grow as a global business in long terms.

Positive:

Recycling plastic

Negative:

Prolonging fossil fuels exhausts

To Mase

Hi Mase:
You can think for example in extracting Hydrogen from the oil produced by this way because the base are the CH groups.
We are all in love with hydrogen because its clean, H2O instead of CO2 as emissions, clean electricity, etc, etc, but most of the hydrogen available comes from fossil fuels.
Ironic, isn´t it?.

Condensator

Hi everybody
What is a good design for a condenser.
a) Big empty tank.
b) Container full of anything for max. gas surface area.
c) Long container with different tapping points. As the gas cool off, thy condensate and go to different storage containers.

Thanks
Alec.

[well]

Hi i'm a student in energy engineering and i'm working on a project about turning waste plastic into fuel but sadly more on the business side.
So i would like to know how much energy is required to perform the process?
I made my own calculation using the heat capacity and the enthalpy of fusion of the PE and i found that we need 0.3 Kwh for 1 kg of PE (to heat the plastic up to 350°c, hope your talking in °C in the description by the way). It seems to be too weak for me.

Thank you for your help and really good job for those who manage to build this system, it's fantastic!

[otpadnoulje]

well, books said , 2200 Ws per kg for cracking + 600 Ws per kg for heating up to 400 c.

All process, heating and cracking = o,77kWh per kg of waste plastic.

my experience for waste motor oil is 0,5 kWh per kg.

Hope this will help

Alec, whatever design of condenser you come up with it almost certainly wont work perfectly first time. it will need to be adjusted to separate the fractions correctly. An empty tank will work but baffles will make it more efficient,

Im constructing a pair of condensers at the moment from 11kg gas bottles. To start with Im not going to use baffles but i may have to change that.The first will be heated and the second air cooled. The length of the pipe joining them will be one way of adjusting the outputs.

[munkeyflavamuffin]

So impressed!

Just a quick post to say how impressed I am with this tread and forum in general really. The Diesel you produce would probably be illegal in the UK, im going back to read the 20 or so pages I haven't had time to read now )

440V? no way!

Hello Jetijs ;
In my country 220V A/C power in single & three phase is available .
First I SIMPLY connected TWO phases of 220V each with the band heaters.
This gave the 220+220=440V .

Now I simply connect single phase 220V (One neutral & One phase of 220V).
This heats the reactor more quickly although consumes more power .

Hi Asad,

I am a new guy but a electronic specialist. your equalision vould be fine, if it would be direct current and not alternatig current.

on one phase , the effective voltage is 230V (equal to a Dc voltage) peak 320V(230V*1,4)

between two phases(which each have an effective 230V) there is 120degree of sinusoidal delay. you can solve it by draw a triange with 120degree and that two sides are 230V legth. belive me, the third will be approx. 400V.

then the electricity provider has a +/-10% garantee, that there will no overvoltege or less voltage than that. it means it can be from 207V to 253V. it depends of what kind of loads has the whole electric system has.

cheers
