How to turn plastic waste into diesel fuel cheaply

[Excalibur]

hello BB system reflux was definitely wrong, or rather non-existent. as you saw in the photo the column was moved at least 30 cm from the reactor and not insulated, so the condensation was to create in the first stage of the column at the bottom. I am now bringing the column in the center of the reactor and all insulated, 1 'stage will lower reflux, the other division. reluctantly try to eliminate the gap.

Sounds good. Temperature thermocouple probes at each of the fractionation column levels would be very useful for tuning purposes.

Reflux fouling

So the reflux serves both as a wetting surface for the heavier fractions to condense upon and separate from the lighter fractions, and as a contaminant removal, like a filter, to remove free-carbon which has been carried over from boil-over. With this in mind, as you might expect, the pad of stainless steel packing which I retrieved from the gas-liquid separator I cut open was fouled with crusty carbon-like material. The pad is 200mm thick by 800mm diameter, has been difficult to clean. Think I might have to separate the mesh into individual sheets to get a proper clean. I guess if we are using something cheaper we would need to just throw it away once the reflux efficiencies decline. And if we have chosen to use rusty iron in the reflux the surface of rust would be covered by carbon and need replenishing.

ciao BB il sistema di reflusso era sicuramente errato o meglio inesistente.come avete visto nella foto la colonna era spostata di almeno 30 centimetri dal reattore e non coibentata,quindi la condensazione veniva a crearsi nel primo stadio della colonna in basso .ora sto portando la colonna al centro del reattore e coibentando tutto,1' stadio in basso farà da reflusso, gli altri frazionamento. a malincuore proverò ad eliminare il vuoto.

Thanks, Excalibur, for referring to me on this. Regardless of whether a fractionation/cracking unit is operated at ambient, or increased pressure or reduced pressure. If, your samples are coming out dark, then it is most likely the presence of free-carbon due to boil-over in your retort. So, in this case, then one would want to work on improving your refluxing system.

Grazie, Excalibur, per riferirsi a me su questo. Indipendentemente dal fatto che una unità di frazionamento / cracking viene azionato a temperatura ambiente, o aumentata pressione o pressione ridotta. Se i campioni stanno venendo fuori buio, allora è più probabile la presenza di senza emissioni di carbonio a causa di boil-over nel tuo storta. Quindi, in questo caso, allora si potrebbe desiderare di lavorare per migliorare il sistema di riflusso.

Good on you for building something so innovative. I have very little experience with vacuum distillation however because you are getting fuel weighing 750gr per liter, the plastic must be cracking. The dark color of your fuel suggests boil-over. Because vacuum will reduce boiling point, perhaps try reducing the reactor target temperature.
BB might be able to throw some light onto the situation as his pyrolysis unit has run under vacuum since he started.

piccolochimico, could ypu please use english language, it is not native to us too, but this way we can understand ourselves. Odlly enough, i can understand more than 50% of what are you saying, and i never studied spanish. Good luck!

excalibur ti ho inviato le mie immagini sulla tua posta.guarda un po.ciao

[piccolo chimico]

excalibur se mi mandi una tua mail personale proverò a mandarle.grazie

[piccolo chimico]

non riesco ad inviare le foto della colonna e le modifiche fatte.ci proverò domani a caricare i fail

[Excalibur]

Thanks.
The weight of your fuel is very light, nearly as light as petrol. Good usable diesel would be around 820 ~ 850 grams per liter.
I await more photos and information on the fractionation column from you.
grazie

Rendered translation from Italian:
good point excalibur, that's what I thought. as you will see from the photos I'm editing the wrong place for the fractionation column in the head with it to create the reflux and then insulate. as regards the empty keep it always lit to avoid clogging, the wax will not find it anywhere, the weight of the fuel is 1500 grams per 2 liters. insulation resembles excalibur but with wool instead of vermiculite

I try to upload photos

giusta osservazione excalibur, è quello che ho pensato.come vedrai dalle foto sto modificando la storta per mettere la colonna di frazionamento in testa ad essa per creare il reflusso e poi coibentarla.per quanto riguarda il vuoto lo tengo sempre acceso per evitare otturazioni,cera non ne trovo da nessuna parte,il peso del combustibile è di 1500 grammi per 2litri .la coibentazione assomiglia ad excalibur ma con lana invece di vermiculite

Welcome, piccolo chimico, nice flanged pyrolysis unit. The translation of your original post did not help me understand your system enough. I am not sure how wrapping insulation around your retort, when you are heating it with a flame will help either get heat into the retort, or insulate the retort. I suppose a flame-heated retort would need to allow the hot gasses from the flame to be directed around the retort to an exit. So, insulation would be outside the path of the hot gasses from the flame.

español:

Bienvenido, chimico piccolo, bonita unidad de pirólisis con bridas. La traducción de su post original no ayudó a entender lo suficiente el sistema. No estoy seguro de cómo envolver el aislamiento alrededor de su réplica, cuando usted va a calentar con una llama ayudará a obtener ya sea de calor en la retorta, o aislar la retorta. Supongo que una réplica de la llama calentado tendría que permitir que los gases calientes de la llama para dirigir la vuelta de la réplica a una salida. Por lo tanto, el aislamiento sería fuera de la trayectoria de los gases calientes de la llama.

Thanks for the picture.
Where is your reflux?
Please make a schematic drawing of the fractionation column. Also weigh EXACTLY 500ml or 1000ml of the product and post the weight in grams.
Does the fuel turn to wax if cooled in a refrigerator?
How much vacuum are you using on the retort?
More pics??

excalibur hello, I am attaching my retort, however, 'the picture is not complete can not be seen with the vacuum pump and bubbler unit. thanks

ciao excalibur,vi allego il mio storta pero' la foto non è completa non si vede la pompa vuoto con gorgogliatore e centralina.grazie
