Back to Basics VI

For a barrel of crude oil, what percentage of this barrel would yield a conventional Lubricant base stock after processing? This question is NOT open to engineering disciplines, Tribologists, chemists, mathematicians, physicists, psychologists, sociologists, or savants.

I like it when we have to start putting disclaimers before beginning any discussions on this board.

Not actually a disclaimer, but in this case we would like all BITOG members who are not listed above a chance to answer. Do you have a proposed answer?

My thoughts exactly

 

[JayhawkRoy]

1.19%

 

[walterjay]

2 quarts

 

[walterjay]

Lets make that 1.2%

 

[Charlie2015]

Less than one quart?

My research says you basically heat the crude oil and collect the different fractions that boil off at different temperatures. About 1% is used for lubricants. While I've studied engineering, chemistry, and math, I'm clueless how to calculate this.

 

[MolaKule]

A barrel of crude is 42 gallons. The refining and processing yields a number of products including lubricant base oil which equals 0.5 gallon. 0.5 gallons/42 gallons = 1.2% rounded up. JayHawkRoy and WalterJay gets the virtual BITOG Mug with the embossed emoticon and 0.5 gallons of virtual full synthetic oil.

Yes, I understand that but is it the same for all barrels or crude? That fraction is constant barrel to barrel?

We didn't see a numerical answer from you but this information came from the API itself. I have to assume the yield figure they quoted is an average over many types of crude's and processes, as I think that is what you are alluding to.
