For a minute there I thought I had to get off my couch, when all the while the fact is we don't have to do anything much but keep things afloat for just a few decades more! In fact, we'd best shut up about PO, because if our offspring finds out we knew about it all along, they'll turn and wring our necks come 2036!

“Most refiners couldn’t take more sour if they tried,” said one refiner, who asked not to be named.

“We have a glut of sour crude and a short supply squeeze on low sulphur crude oil and products, so extra Saudi makes no difference whatsoever,” a physical oil trader said.

I give credit to NBC news. They have been posting some rather tough articles lately and asking the hard questions. I'm amazed that anyone would admit to this.

Anyway, what do the refineries do with the sulphur they remove from the oil? Does anyone know if it goes on the open market or disposed of as waste? If it's disposed of, I hope it's done in a responsible manner. Sulphur and all of its compounds tend to be pretty nasty/toxic stuff.

Looks like they've tapped into Manifa, as many have been expecting. That's not only sour and sulphorous, it's loaded with vanadium from what I've read. Tough as nails to refine.

I don;'t know but on the map it looks pretty big in the maps I've seen. Some sites claim 41 billion between Manifa and Khurais, another untapped field (I don't know about Khurais).

Of course they don't mention that Manifa is really low grade sour oil, just that it's there and there is lots of it.

Here's a good article that profies Manifa:

The sulphur extracted by our local sour gas plant comes out molten. It is simply poured out forming a huge yellow block. I will take a picture and post it next time I'm there. Sometimes we see a rail tanker labled "molten sulphur" going by but the supply exceeds the demand so the block keeps growing.

Keith,

Thanks for the info about sulfur. I'm suprised that elemental sulfur is so harmless while many of it's compounds are pretty nasty. You say that you guys have a big molten block of sulfur sitting around waiting for someone to come buy it. Does the sulfur have to be protected in anyway in order to keep it from oxidizing and turning into sulfur oxides which are not harmless?

Depends on your definition of nasty, the veterenary use in the second link was a laxative. Smile

It comes out of the process molten hot. They pour it on top of the block and it cools and solidifies.

Now you've got me worried so I've done a bit of research.
It's like the Kazakhstan photos here:

Notice the big blocks behind the tanks.

There have been some nasty sulphur fires:

Devco has a facility:

Back to main thread here, so the Saudis are saying "We can produce X million BPD," (e.g. 11.5 million) but in fact what's going on is an increasing percentage of that is sour and/or otherwise difficult to use or has lower economic value.

So in effect, what that means is they've basically peaked and they're scraping the bottom of the proverbial barrel to make the numbers look good. Or am I mistaken..?

Yes. It appears that way.

In fact I think it's been this way for some time now.

*sigh*

Some refiners can process sour and some can't. Some refiners (see Valero) have made the investments to run sour in their refineries. This is paying dividends now as sour sells at a $6-8 discount to sweet.

Any refinery can be updated to process sour crude, just requires investment.

Does the discount of $6-$8 on sour make up for any additional costs in refining it?

Not if the price of gasoline is any indication. Valero has a couple of stations around here and they are usually at the low end of the price spectrum. Very smart of them to invest in the tech to refine sour crude.
