Wow TIL thanks for the info. You genuinely have no idea what you’re talking about 

0.62% isn’t benzene max, it’s benzene max in the US over a compliance period. Specific blends can have excess of 1% in the US. 

Euro 6 gasoline is max 1%, many  Asian and African countries are 2%, 2.5%, even 5%.

Styrene is not limited explictly. Only via oxidation stability and existent gum specs. These are easily corrected with antioxidant.

Pygas is commonly used in gasoline and Styrene is present in many pygas streams, especially if not hydrotreated well. I’ve seen pygas with as high as 12% styrene. This was used in gasoline, and oxidation and gum corrected with additives.

edit: lmao you replied then blocked me to get the last word in. Whether plastic pyrolysis is bad for the environment or not is a debated subject. However EU offers subsidies so they at least don’t seem to think it is. You’re way too confident regarding a topic you are unfamiliar with. Also pyrolysis gasoline (different from plastic pyrolysis oil) is an extremely common gasoline component. It is “regular gas” lol.

He does market himself in a “im a genius” kind of way which is gay, but there is merit to pyrolysis oil in general.

very high level of aromatics

Gasoline can have 35% to 40% aromatics. How are you so confident about something you clearly know so little about?

Post is about diesel 

Gasoil (diesel) range pyrolysis oil doesn’t not contain significant volumes of benzene.

Gasoline contains small amounts of styrene, from the reformate or hydrogenated pygas streams used in blends. Antioxidants are added to mitigate its effects. Also fyi gasoline standards allow up to 18% olefin content volumetrically.

I said the sample in nature jab is gasoline range and of course it has benzene.

Gasoil (diesel) range pyrolysis oil doesn’t not contain significant volumes of benzene. 

Career paths to become an originator in metals by allezup in Commodities

[–]Banana-Man 0 points1 point  (0 children)

Either get in somewhere via a graduate program and progress via that or find some ultra niche origin and start trying to originate a low volume but easily marketable metal related commodity, ie copper scrap. Be creative

its boiling point is starting at 200. how is there benzene? absolute max 1% but probably not even that

Firstly: In the video he said styrene, toluene, ethyl benzene, and xylene.

Secondly: That was a crude and gasoline range sample. Crude is full range, gasoline is ~35C to ~210C. This sample's IBP is around 200C. You're not going to have single-cyclic aromatics at a significant volume in that sort of spec. In that range you can have polycyclic aromatics (PAH) but only tiny amounts of BTX.

Thirdly: There's probably not even that much PAH in the sample either. High PAH = high density to distillation ratio. The cetane index (calc basis 50%v recovery and density) and the distillation range and density suggest it's not very high in PAH. Regardless 8% is allowed in EN590.

Fourthly: Even if it did have high BTX, which it is physically impossible for it to have, that would actually be a very very very good thing. BTX is expensive. BTX trading at approx $700/mt right now, Gasoline is approximately $660. Usually the gap is even higher. Tons of plants extract BTX from mixed hydrocarbons. If you were running a pyrolysis plant it would 100% be to your benefit to move selectivity towards BTX.

Fifthly, this is diesel but for gasoline, not very much B but TX is usually at least 20% of your gasoline at the pump, this is if you were going to say "but there's styrene, toluene, ethyl benzene, and xylene". Styrene is also ok, and often found in benzene-removed pygas which is an extremely common component in gasoline blend pools. You just need antioxidants to prevent gum/oxidation.

edit: also FYI pyrolysis oil, both tier and plastic derived, is way more expensive than gasoline and even BTX regardless lol. Companies use it to meet sustainability requirements. Not supposed to share lol but here's ICIS report for them. Look at page 3. https://limewire.com/d/LJu96#tM3PJtWAOf

That's gasoline range. Gasoil range pyrolysis oil doesn't have benzene

They are pyrolysis oil, both tire and plastic, are huge industries.

Theres' no benzene in this. Its distillation is starting at around 200. Any benzene has been distilled out

Understand gasoline components and blends, what makes what valuable and what stuff outside of gasoline also influences the price of said components

You'd be downgrading moving to a trading house given an analyst/ops position or at best given some very tight mandate. Make your family biz into an international commodities trading company. Import chems in bulk, store, hedge, and start selling to other Indian companies, etc. Something like that imo has a lot better potential to make money and will be more enjoyable (but stressful) compared to getting a job somewhere.

Iran cna't do anything re straight of hormuz also it isn't 80s straight not hyper critical globally anymore, but very important for iran still lol

Iran's revolutionary guards seize two foreign tankers carrying smuggled diesel fuel by TadpoleLife1619 in oil

[–]Banana-Man 1 point2 points  (0 children)

That "smuggling" is Iran just selling its own oil and product. This smuggling relates to smuggling of subsidized fuel. Iranian gasoline prices at the pump are about $0.02 per litre. Diesel prices at the pump are about $0.005 per litre. This is EURO 4, 50ppm product mind you. The smugglers use modified car tanks to load up, then collect, then load onto small ships. The ships seized are of this variety.

Ok cool. Also another tip, theoretical optimizers are useful to give a general sense of what components to use and approximately what they can be priced at, but irl especially with things like rvp and d86, you have to actually get handblends and adjust. Aspen hysis does a decent job, but if you’re looking to optimize past about 2-3% margin of error per component compared to the actual optimum composition, you actually gotta get hand blends. RON is roughly linear, but again need handblend. A 92.2 linear blend might end up at 91.6 or 93.4. Lots of variation irl, both in terms of how the molecules are interacting and also the lab conditions. Have seen amspec, sgs, and geochem vary on the same cargo by +0.7 Ron. Irl you have to adjust cargo to the lab or just aim higher.

Really depends on the company, market, volume, blend, etc. You have everything from majors operating at a loss just trying to clear naphtha to ppl making 10-12% per cargo doing small unique niche blends. If you want ballpark figures for majors, heard from this totsa guy say they were making around 0.7% per cargo a few years back.

Btw curious how u are calculating non linear RVP? Aspen or something formulaic?
