Well said! Oil -> plastic -> oil with a little chemistry makes too much sense.
It's not "a little" chemistry, the process is thermodynamically unfavorable kind of like pig -> sausage -> pig. There will have to be a net input of energy which may come from combustion of other plastic waste.
Perhaps you should focus on the meaning of what I said - the importance of getting rid of excess plastic to make oil is a good thing - rather than my poetic license taken in the amount of chemistry required.
Or
If you had heard me in verbal conversation you would have understood my meaning better.
Pick one.
None of the above.
The polymers are assembled from monomers derived from brute force thermal cracking of crude oils & NGLs (sausage) along with some production from fluidized catalytic cracking units (FCCU's).
Assembly of the monomers into specific polymers followed by molding those polymers into desired shapes / thicknesses, etc. requiting plenty enery (pig)
Pyrolosis for thermal decomposition of poymers into char residue and petrolem /petrochemical mixture (sausage).
No more seperation science nor energy is required gor recovery from pyrolysis than yhe initial fractionation of crude oils & NGL's, with ptoper cuts then bein routed to conversion units (steam crackers, cokers, FCCU's) which then have their own fractionation trains. It's actually likely less.
I do have over 2 decades first-hand experience with such -how about you? Your profile's a ghost.
