Question on sour crude

Unread postby grungerock » Fri 01 Oct 2004, 05:34:17

Isn't it that 'sour' crude produces less volume of gasoline due to the higher sulphur content? In other words, 'sour' crude is not worth it as it takes a lot of nett energy to produce gasoline?

naw, theres plants in the US and other places that specialize in "sour" grades, and do make gas from them. Also "heavy" grades like asphalt can be cracked as well...

But you do get less benziene from them, and it takes more energy to do so...

However their EROEI (energy retruned on energy invested) is usualy very positive, else we would not be pursuing the even less optimal "Tar Sands" of North America.

In fact the price difference between sweet & sour crude makes refining sour more profitable for many refiners.
The problem is, of course, that not only is economics bankrupt, but it has always been nothing more than politics in disguise... economics is a form of brain damage.

Are sour crude and heavy crude included in countries oil reserve figures?

And how much sugar does it take to turn sour crude into sweet crude? And will sugar substitutes work, like aspertame?

Reserve reports include all "proved reserves". Canada allows reporting (I believe) of tar sands.

The SPEE (Soc. of Petro. Eval. Engineers) discusses the merits of the differing reserve descriptions.

You are right, but they still only come out at 16.9 billion barrels as they are only allowed to declare 'sites under active development' or they would be a lot higher.(170 billion - 300 billion URR?)

Take a look at the asponews.org website. Colin Campbell does an excellent job of breaking down conventional (or regular) oil vs non conventional reserves. The latter has a much lower EROEI.

Other thing is Venezuela has enormous amounts of Heavy crude? These are not included and so does Saudi Arabia and Kuwait (500 billion barrels just for the former). Has none of this been evaluated to see if some can be recovered? Even the UK is evaluating heavy crude deposits and according to this link they now say they have the technology to recover this oil which wasnt available in the past(28.5 billion barrels according to the first download)

Will not prevent PO, but may help provide enough fuel for essential industries in the UK?

Man, these people think up some cruel acronyms. DTI SHARP.

... "Sustainable Hydrocarbon" ...

Bet they can't explain the Sustainable part.

PB, You may want to monitor the RML forum. One poster has asked some specific details reafrding this heavy oil.. It will be interesting to see what spin DTI come back with.

Well, keeping a sense of humor here, I suggested an almost unlimited source of new refinery feedstocks would be to use continuous liposuction on the Krispy Kreme donut girls featured in their calendar.:-D :lol: :roll:

I read a story today about how bacteria are "eating" almost half our worldwide oil reserves--that is, turning it "sour" or "heavy." This does not do one's stomach a lot of good :oops: ...not that Peak Oil and The Crash keep it in the best of health! :lol:

Uh--powerdown? Solar/wave/tidal/wind as limited, but useful, power sources? How about a nice OLIVE oil lamp? Sometimes I feel like this teeny-weeny voice in the engine room of the Titanic--just before it hits the iceberg.... :(

Well that puts a new spin on 'heavy' oil.

Now that's one from the WaaaaayBack machine (not to be confused with Peabody's WABAC) 8O

$this->bbcode_second_pass_quote('', '[')b]Wayback Machine

The Wayback Machine is a digital archive of the World Wide Web and other information on the Internet created by the Internet Archive, a nonprofit organization, based in San Francisco, California, United States.....

History

The Internet Archive launched the Wayback Machine in October 2001.[4][5] It was set up by Brewster Kahle and Bruce Gilliat, and is maintained with content from Alexa Internet.[citation needed] The service enables users to see archived versions of web pages across time, which the archive calls a "three dimensional index".[citation needed]

Since 1996, the Wayback Machine has been archiving cached pages of websites onto its large cluster of Linux nodes.[citation needed] It revisits sites on occasion (see technical details below) and archives a new version.[6] Sites can also be captured on the fly by visitors who enter the site's URL into a search box.[citation needed] The intent is to capture and archive content that otherwise would be lost whenever a site is changed or closed down.[citation needed] The overall vision of the machine's creators is to archive the entire Internet.[citation needed]

Information had been kept on digital tape for five years, with Kahle occasionally allowing researchers and scientists to tap into the clunky database.[7] When the archive reached its fifth anniversary, in 2001, it was unveiled and opened to the public in a ceremony at the University of California, Berkeley.[8] ......

..............As of July 2016, the Wayback Machine reportedly contained around 15 petabytes of data.

The really specialist refiner prefer sour because they separate out all that sulfur and sell it as a nice sideline to refined products.

Yes. Very lucrative. There's a huge shortage of sulfur.

Yup, one of the main uses of Sulfur is in fertilizer which leads to a seasonal demand cycle, in the low seaon it accumulates and in the high season the stocks are drawn down again.
