How to turn plastic waste into diesel fuel cheaply

[Beyond Biodiesel]

Thanks for the photos batwicho, the bottom clear liquid in your sample must be water. I guess the cloudy layer is either an emulsion layer, or wax.

YES, the bottom is water, the emulsion is some "waste". Next week i'll have answer from our laboratory about the mix.

this is my pyrolysis design retort,reflux and lst condensor l am going to do another condensor and bubbler if some one can help me? my question is to purge the system what l can do? l read that l can put some water in retort? thanks

Purging

You could test it for leaks with water?

But there is no need to purge it, the gases produced when it startes will purge it

You could run a compressor to pull the air out as you start, I have tried that and it seems to speed things up...

ok thanks my friend l read everywhere about risk of explosion? l dont think its very dangerous?

did u have some pictures to take an idea for compresor ? what type?

Dangers

We use the batch machine indoors, we tested it outside, but it was cold

If there were any chance of blowing ourselves up it would have happened by now.

The new continuous loading machine we have developed is now up to version 3 due to problems with the plastic becoming unworkable as it changes from fluff, to waxy solid to a liquid.... we have had to keep re-designing the hopper...

During our steep learning curve we have had some serious vapour releases, pressure build up and fuel being squirted out of the hopper... in fact everything that could go wrong has.... and we are still here, no burns or missing fingers...

Just dont use candles for lighting and avoid sparks and smoking when something goes wrong.... as long as your kit is designed properly, it should be safer than walking up and down stairs



The compressor is a small lab one that can be used for sucking or blowing... it has barbed fitting on the in and out

Hi Jonathan,

Where are you located ? - Looks beautiful wherever you are!

This is a common vacuum/compressor pump.

If you are going to pull a vacuum on your retort, you should make sure it can handle a pressure differential of 15PSI before you heat it up with a load in it.

thanks for help nice pump in malta its dificult to find pumps like that l buy my temp controller and sensor from ebay

The easiest thing to do in my opinion is obtain some CO2 or nitrogen and use it as a purge gas.

I welded a small diameter pipe coming off the bottom of my retort and then attached a hose barb to that using a coupler.

Make sure your small diameter pipe is sufficiently long if you're using a rubber/silicone hose for your gas. I had to extend mine because the hose began melting.

l cant buy that type of gas l try to buy he tell me that l want license to buy co2 or nitrogen l try to find compresure so wwhat l want to do? first start compresor start retort and leave compresor on? can l use compresor from air compresor?

Most compressors pumps used in air compressors cannot be used as vacuum pumps. Since you cannot get CO2, and a diaphragm vacuum/compressor pump is not available to you, then put water into your retort with whatever you plan to crack before you turn it on. The water will displace O2, and as long as your pyrolysis unit is leak-free, then it should operate safely.
