Q: Contributing badges by up-voting. Is it a good idea?

Nilay GhoshFor some time, I have been stumbling across some questions/answers that has 9 or 24 upvotes. So, I thought that I should upvote the question or answer so that they get the "nice question" or "nice answer" badge. Some unlucky users asks or answers a good question or answer but eventually gets...

@IͶΔ can you do a MATT of radius for me? I’m horribly bad at MATT’s .__.'' — Jan 23 hours ago
WTH is "MATT" @Jan?

Just a question:
How is crude oil collected at each layer of the distillation column?
 
IͶΔ
IͶΔ
@Leuchte Lemme remember . . .
They have certain places, er, plates (?) for them and they collected them with pumps.
I only remember it crudely.
I think a little documentary or what can explain it in great detail.
It's no big secret.

Unfortunately I can't find which side the crude oil is collected
on the side with the bubble caps or the side without a gap?

This image is more accurate than you might think.

This is the diagram I've made so far:

Those places that stuff gets condensed in have a nice name, and I totally forgot it.

It makes more sense as to how the crude oil flows down the column
 
IͶΔ
IͶΔ
@Leuchte What?
 
Leuchte
Leuchte
So when the crude oil overflows the top of the bubble caps, it goes over the side and trickles down.
 
IͶΔ
IͶΔ
Crude oil is pumped from the bottom of the tower.

For example:
Apparently not so
The issue is that some diagrams are conflicting
So my main two issues are:
1. How is the crude oil collected at each layer?
2. How is the crude oil vapour fed into the fractionating tower?
 
IͶΔ
IͶΔ
@Leuchte The stuff condenses and is flowed into pipes.

5:46 PM
But where?? :)
 
IͶΔ
IͶΔ
@Leuchte Usually pumped from the bottom of the tower. Just from somewhere you can heat it a lot so that almost everything it has evaporates, so it makes sense to do it from the bottom.
Look at it. LOOK at it.
 
Leuchte
Leuchte
If you put the feed system at the centre of the tower, some of the crude oil can rise and some can condense and fall?
Also, I'd like to note that I think that diagram comes off GCSE Bitesize for high-school students so I think it has been oversimplified. For instance, how can the crude oil at the top fall all the way to the bottom in the gap?
 
IͶΔ
IͶΔ
@Leuchte Nothing falls.
The oil is heated, so almost all of it except some bitumen evaporates.
Then as we rise in the tower, it cools down.
To the point of the melting points of its components.

The gas is ultimately gathered at the top.
@Leuchte Isn't that process obsolete?
But it could work.
 
Leuchte
Leuchte
5:51 PM
Which process?
 
IͶΔ
IͶΔ
@Leuchte Pouring it from the top/center
 
Leuchte
Leuchte
I don't know - I can't find any evidence from a scientific, primary source

@Leuchte :(

I guess I'll have to find someone who works in an oil factory to find out more. Thanks for your time and patience though!
I'll come back to you with the info if you wish

I just read a Russian chem textbook page that says that in ozone, the central oxygen has its 3s shell utilized.
Quite cool
 
IͶΔ
IͶΔ
@CopperKettle I don't think about it that way.
It's s, p, d, f in atomic orbitals.
When a molecule is created, you have new orbitals.
Beautifully shaped, complex, and awesome.
I rather study those.
It might be useful to explain the involvement of AO's for bonding purposes, but after the bonds are created . . .
 
CopperKettle
CopperKettle
I see, it might be a simplified explanation.
 
IͶΔ
IͶΔ
7:09 PM
Not simplified, no.
It's just something that doesn't exist anymore. You don't have any 3s orbitals in ozone.

@CopperKettle Really doubt such high energy orbital would be used to create any MO there in any significant way

What am I suppose to see here? An i-Pr behind an s-Bu or an s-Bu behind an i-Pr? http://imgur.com/khQRaNd
I know that bond means "What follows is behind", but all the lines are equal in length.
