  Instantly I'm reminded of "That Time I Tried to Buy an Actual Barrel of Crude Oil"https://news.ycombinator.com/item?id=43761572https://archive.is/kLFxgWhich leads to "Planet Money Buys Oil"https://www.npr.org/sections/money/2016/08/26/491342091/plan...

  if you liked this and the history of the industry, "The Prize" is a fantastic read!

  My father actually works at the Jamnagar refinery. I was bought up in there seeing and visiting the refinery as families are allowed for some trips every now and then. I learnt a lot of this process of refining out of curiosity of what my father did and it was just so cool. The refinery in context is the world's largest since more than a decade and seeing it with your own eyes, it feels like a wonder of the world for real. Truly marvellous outcome of perseverance and engineering. Loved to see this blog on the HN homepage, its very well written

  The article is quick to point out the huge role of oil in the modern energy mix. It also fails to note that most of the energy ends up us waste heat. The so called "Primary energy fallacy". Other than that, it's a great read.

  As someone with no real-world petrochemistry experience, but much gaming experience, I was very surprised how familiar the crude oil processing diagram looks. Factorio and GregTech are two prime examples of fairly realistic oil processing lines (probably as accurate as any game would reasonably try to be).

  The article does a good job of showing how a typical barrel of oil is converted into a dozen or more distinct usable products.It would be helpful to also have a chart that shows how much gasoline or diesel as a percentage of each barrel is produced. It would be a bit variable, since not all crude oil is the same, but I think it would be close for most of it.Some people think when diesel and regular gas prices diverge, that they should just be able to produce one at the expense of the other; but the distillation process shows that they are fundamentally different.

  I find it amazing how "naphtha" can mean crude oil, diesel, kerosene, gasoline or kind of white spirit.EDIT: oh and it comes from Akkadian! how many Akkadian words do you know?

  If you're interested in how the oil industry as a whole operates and why, Oil 101 is an interesting read.

  This is a really good overview of oil refining. I'll add a few things.1. The light and heavy distinction is covered by a measure called API gravity [1]. The higher the API gravity, the lighter the crude;2. Refiners mix different crude types depending on what kind of refined products they want to produce;3. Heavy crude tends to be less valuable although it's essential for some applications. Lighter crude produces generally more valuable products like gasoline, diesel and avgas. But heavy crude goes into construction (eg roads) and fuel for ships (ie bunkers));4. Most refineries in the US are very old and are very polluting. They don't need to be this way. A new refiner would produce vastly less pollution but they're almost impossible to get permission to build now. One exception is the Southern Rock refinery currently being built in Oklahoma [2], which will be powered by largely renewable energy and produce a lot less emissions than an equivalent older refinery with the same capacity;5. There are different blends of gasoline that the US produces. The biggest is so-called summer and winter blends. What's the differene? Additives are added to summer blends (in particular) to increase the boiling point so less of the gasoline is in gas form because that produces more smog;6. California uses their own blends so in 2021-2022 when CA gas went to $8+, it wasn't just "gouging". It doesn't really work that way. CA requires a particular blend that only CA refineries produce so it's simple supply and demand as no new capacity gets added to CA refineries and demand goes up with population growth.The reason for the CA blend goes back to the 80s and 90s when smog was a much bigger problem. Better vehicle emissions standards since then as well as improvements in the blends the rest of the country uses have largely made the CA blend obsolete so CA is really paying $1+/gallon more for literally no reason; and7. California doesn't build pipelines so is entirely dependent on seaborne oil imports (~75%) despite the US being a net energy exporter. Last I checked, ~20% of that foreign oil comes through the Strait (from Iraq, mostly) so, interestingly, CA is more vulnerable to the Strait of Hormuz closure than the rest of the country.I guess I'll add a disclaimer: I'm very much pro-renewables, particular solar. I think solar is the future. But we currently live in a world that has huge demand for oil and no alternatives for many of those uses (eg diesel, plastics, construction, industrial, avgas) so we should at least be smart about how we go forward.[1]: https://en.wikipedia.org/wiki/API_gravity[2]: https://www.oklahoman.com/story/news/2023/05/24/5-6-billion-...

  Cool to see how when people talk about “transitioning off oil” it's more than replacing gasoline in cars. It's replacing this entire global machine.

  Oil is cooked. BYD is filing 52 patents every single day and has a 700 km in 9 minutes vehicle available TODAY ! Charging by Solar is going to be the norm. Watch : https://www.youtube.com/watch?v=vgCYYrhL-kE
