⚡️ Novokuybyshevsk, Samara region of the Russian Federation — a hit on the oil refinery.
Wow, that was a fireball to mention! What structure especially did they hit?
I’m by no means an expert in the oil refinery process, or in modern warfare techniques, but my understanding is that Ukrainian drones largely target what is called the Fractionating column, which is the heart of a refinery.
In a nutshell, oil is refined by heating crude oil and drawing off liquids at different temperatures. Fuel oil liquifies at one temperature, lubricating oil at another, kerosene at another, etc. The fractionating column is where all of this takes place. You can see a simplified graphic here.
Since that’s the key component of a refinery it’s obviously a prime target for drone attacks etc. And if the refinery is in active operation then it means there’s plenty of volatile fuel around to create a fireball like this.
https://en.wikipedia.org/wiki/Fluid_catalytic_cracking. I did maintenance shutdowns on them thirty years ago. They would be a good target since inside them are all kinds of different petrochemicals. Many are unstable and don't need any help exploding.
My understanding from reading various articles about past refinery attacks is that there are some components in fractionating columns that rely on Western components, and are difficult for Russia to replace while it's under sanctions.
The drones are small and the refineries are designed to handle sudden failures in the system and fires. Ukraine likely has some experts directing the targeting of the most difficult to replace or explosive parts. So they get the best bang for their efforts
Given the size of the fireball I would guess that they hit something close to the end of the production line for diesel/gasoline.
Definitely the case, because I was reading some independent ukrainian analysis on early deepstrikes vs refineries, some key components were targeted that are irreplaceable. All those deepstrikes are a long chain of spying, analysis, desicions, logistics, execution - with many people and time involved into each case. And ofc we see only successful ones. Huge amount of work been done there.
