What f@@k is this? (Video in Russia)

A pipe.

Looked like a massive drainage pipe to me.

Submarine ?

And we have a winner.

Ok thanks, I did an assignment on those many years ago so that explanation makes sense

Looks like a pair of tits at the front.

Defo a pressure vessel of some kind, whether crude oil or other distillation.

To expand a bit on dorothy's reply, if you wanna separate say oil and water you can boil it. The water will boil first (and rise up)and you capture and cool the steam off the top, and drain resulting pure oil off the bottom.

You can separate 3 or more things the same way, so long as you have vertical separation (a column) which allow different layers to form. If you balance heat, inputs and outputs, you can continually pour in your mix and continually extract your different substances.

These columns as in the vid are filled with trays with different stuff on them, some looks like marbles, or grit, or small cubes, etc. Hot gases can rise and cooler liquids can spill over and down to the next level. Each product automagically finds it's own level and so long as you have a stable reaction you can pull out fairly pure stuff from different levels.

Pretty hilarious that these guys are calling this a UFO.

Pretty much like a vigreux fractionating column.
Do you have an interest in chemistry Kiteboy Dave?

I call bull* on that.

This is a device called Big Bertha.

Into each of those portholes you insert flouride, aluminium chaff, inorganic toothpaste, bigMacs, tin foil hats, isocol, GM wheat, polio vaccines, irradiated lettuce, thermite strapped to a concrete pillar, nano-particle sunscreen, marijuana, a Cabrinha kite and a Severne enigma boom head and magically (well actually using alien technology modelled on crop circles) out the bottom comes :

The stuff the lizard people use for chemtrails.

Some interest, I like the concepts in physics more but I struggle to get my head around the math.

But in this case my interest is in refining. When I worked at the refinery I soaked up pretty much every document that I could access. Refineries are just a big chemistry set that costs a million dollars a day to run.

Here you can see the trays being loaded inside a column. The 3rd pic they show catalyst shaped like wagon wheels.

Whatever it is it looks like it would have been easier to assemble in place.
