Old-school oil refinery flowchart, Chemistry For Today (1961, inside cover)

Both images in the Google Drive folder are the same, one is just recompressed (still almost 3 megabytes)

Niiice !
(But what happened to Petroleum Gas ? Were they just flaring if off at the time ?)

"petroleum gas" would be the hydrocarbon gases. The icon in-game is even methane (sort-of, it's the wrong shape) The icon in-game is ethene, didn't see the two carbons

Yeah, but in your flowchart, they are made by cracking (mostly?) gas oil. (ugh, these names...)

Whereas in those I found on wikipedia, they are shown to be directly produced ?

[Edit to add]
The only thing that triggers me as in any way unrealistic, is gasoline vs petroleum. They are the same thing, but interchangeable names (British commonwealth English vs US English) and I find it hard to reconcile every time I come across needing one or other for a recipe. I've grown used to being able to switch between, and use them depending on real life situations. Nexelit, is a fantasy substance, and that I can handle I hasten to add. :D

But there's no item called "petroleum".
Hmm, is it still about "vanilla" Petroleum Gas ?
Because (despite its icon of Ethene = Ethylene ), the fractional distillation schematics are pretty clear about it ?

So, for vanilla :
Petroleum Gas = Butane & Propane (gases, not liquids)
Light Oil = Gasoline(Petrol), Kerosene, Diesel Oil, Fuel Oil (liquids)
Heavy Oil = Lubricating oil, Parrafin Wax, Asphalt (Quite viscous liquids)

Ethylene is a precursor to polyethylene, a plastic. It's commonly produced by steam cracking of Ethane, which itself comes from either Natural Gas (1-6% Ethane, 94-99% Methane - yes the same CH4 that is produced in Py by those plants in the blue glass greenhouse (bluehouse?), what is their name, damn it ?!)
- or Ethylene is also produced from Petroleum Gas it seems, which in addition to Butane (C4H10) and Propane (C3H8), contains a little bit of Ethane (C2H6) ?
Or are these schematics simplified so much that they just compressed the whole flowchart into one tower ? (And the distillation process generates no gasses ?) Sounds somewhat unlikely to me...

We are talking 1961, where a need for plastics wouldn't have been as great, and there may not have been integration in the oil fractionation itself for one reason or another. The order of the outputs is still the same as other towers, but the top doesn't go lighter than gasoline.

Here's a diagram which is more comparable:

Hard to find anything nearly as old, sadly. (and 1960 wasn't that long ago, come on).
