Hello, I've been reading this forum for over a year I've been slowing increasing the size of my setup im now building a 500 gallon reactor will be done next week, i am pursuing this as a business. I live in Jamaica and per liter of diesel costs 1.17 USD yes not gallon liter and that's not ulsd i have been supplying boiler companies as i am up for a grant so i can afford the proper equipment i operate out of the dump at a scrap metal yard wmo= free pp/pe plastic = 1 cent per pound USD so at least living in 3rd world countries has its advantages anyway thanks to the people on this site i am able to do this so much easier to read and learn from other peoples experiences and results will post pics when finished the 500 gallon.Comment

Well done and I wish you an exciting future. You will have some challenges ahead and the first one will be trying to ensure you have a pure plastic type of the PE/PP type, without other types slipping through.Originally posted by Renewable Rtesources View Post
The other challenge will be the Fuel produced, as in, creating a product of quality that can be sold. Producing Fuel of quality is really the most complex and challenging issue. The Pyrolyzing of plastics becomes the easy part.Comment

The quality of fuel is more flexible with boilers i don't try to mess with piston engines just as long as long as i distil the naphtha gasoline and keep the diesel fractions i measure viscosity just by comparing times to pump diesel at room temp over a meter long 2mm rod longer it is more accurate for me i would like to know if blending my wmo diesel with the naphtha gasoline from plastic is feasible say between 85%-90% wmo diesel plastic naphtha gas 15%-10% to adjust viscosity along with sta bil fuel stabilizer diesel 100liter to 0.3 stabilizer also i find it hard to mess up pp plastic hdpe ldpe may give waxing question how would prevent waxing from pe as i do not want to make candles factors temp catalyst ect. There maybe something I'm overlooking at times any good experienced advise would be niceComment

Yes, perfectly OK to blend heavy fractions with lighter fractions like gasoline to make diesel at a usable viscosity. I normally limit the gasoline to 20% max. Gasoline with an ethanol content is more of a problem because the injector pump seals compatibility. In your case I expect you are meaning gasoline and naphtha that you make from plastic. When I'm cracking diesel, I don't separate the gasoline's, naphtha's etc and I do it by only maintaining the diesel reservoir at about 60°C. In this way only the most volatile fractions LPG, benzenes, etc are removed. My condensers are of course in series.
On the subject of waxing, this has been talked about over and over. There are numerous posts detailing the causes and fixes. In short, reducing the reflux temperature has cured the problem. Also taming down the heat force applied to the retort so the contents does not superheat. Careful monitoring the temperatures in the retort, reflux and actual applied-heat temperatures are recommended.Comment

flashpoint?
What is the procedure if you have diesel with a lower flashpoint?This will not effect run ability of product but may effect volatility whilst handling? Any way to increase this value?Comment

Excess Gas
Hello.
Is there any way to completely scrub the excess gases and turn them into water or non - flammable state as the BLEST machine claims to do? I currently just burn the excess gases but would like to just get rid of them completely. Any ideas?Comment

The way I see it is this. Hold the diesel at a temperature that allows the lighter fractions to evaporate off. More or less, the lightest fraction will come off first, followed by the next lightest, etc.Originally posted by rozier56 View Post
60°C is what I use but higher or lower would work depending on the desired target flashpoint and the timeframe to achieve it.
So, in effect the more light fractions you can extract, the higher the flashpoint figure will be. I suggest to save energy, do it "on the fly" as you are making the diesel. Also it would be worthwhile to re-condense those extracted light fractions for other uses. An ice quench condenser could maximize the fractions condensed, else any non-condensables could be flared off or used as heat.Comment

What is the ideal temp range for retort and reflux to produce liquids when using hdpe and ldpe research give a bunch of different ranges. Still i would like mostly diesel range. Pe plastic seems to have a temper mental thing about it. One day fantastic the other not so fantastic at same temp range. Will water in retort affect results so dramatically. i am using clay pots that are made in areas of bauxite mining. Is there any other catalyst that can be added i cant get zeolite ill have to ship that in.Comment

We have discussed the temperatures many times in past posts and some of those discussion were not so long ago. You need to do some reading, of which we encourage because of the dangers with what this process can come with.Originally posted by Renewable Rtesources View Post
Zeolite is basically Bauxite. Although there are many mixtures depending on the areas the Zeolites are mined. So some can have other Chemicals like Magnesium etc. in the make up. Unless you are heating the catalyst, it is probably not doing anything. Try doing a run with and without and see if there are any variations in the final product.
Yes water can have a huge impact. You can not raise the temperature of water above boiling till it has turned to steam. Once it is steam, the temperature can then rise. Steam can also affect cracking. In fact, the Oil refining industry uses steam in a process called Hydro cracking. It is high temperature and high pressure, so having steam at low pressure and temperature in the retort could possibly cause a negative result rather than positive.
However, the main issue with water is that you will get a flow of gasses come through early in the process and you are falsely lead to think things are working well. Then it all goes dead for awhile and has you scratching your head as to what has happened. After some time, the gas starts to flow again and you are into the actual Hydrocarbon gasses coming through.Comment

Well seeing as the "off gas" as it is called, is Hydrogen and a little methane, I am surprised the Blest machine, because of it's small size, could turn them into anything non-flammable. But I don't know a great deal about the Blest Machine's operation, so I am just guessing. But I do know that Methane is very difficult to "change" into anything else, without some very difficult processes. Hydrogen can be turned into Electricity via using a Fuel Cell process, but once again, a sizable piece of equipment compared to the small size of the Blest Machine.Originally posted by Babataku View Post
Burning the gas is the easiest means of eliminating them and by doing so also means that any possible nasty contaminants from the accidental addition of a wrong plastic type, should be eliminated. The exhaust Gas of combusting Hydrogen and Methane is Co2 and water. Otherwise all other processes require sophisticated equipment.Comment

Does the speed of quenching the vapor affect the quality of oil dramatically?Comment
-
No and YesOriginally posted by Renewable Rtesources View Post
OK so what do I mean by that.
No, the Speed has no direct influence on the Quality of a/any given Hydrocarbon type. But yes, the quality of the total output, as in producing a specific range of Hydrocarbons from the many, can be controlled by time.
In the "backyard" type processes we are playing with here, the cracking of hydrocarbons is carried out by heat. Heat causes the Hydrocarbon Chains to wriggle and shake violently and if they get hot enough, that shaking will cause them to break apart. The longer they are in the heat and shaking about, the more chance they will break again, creating even lighter chains.
So if you can cool the Vapor stream quickly at just the right time, you will reduce the production of lighter fractions. The problem though, is that we have no way of knowing what has been produced at what point in time, so cooling at any time or speed is going to be a trial and error kind of thing.
It is also why everyone gets a different output result because everyone's machine designs are different.
However, most certainly play with times and report to us on what differences you end up with.Comment

No but to answer more accurately I think we need more information about your plant and setup such as a detailed schematic diagram.Originally posted by Renewable Rtesources View PostComment
