I've verified all the other numbers on this Crude Oil Assay Sheet,

but I can't figure out how they get the Sulfur wt% in the resid oils = 1.408 down in the bottom right corner. Anybody have a clue?

How can the whole crude have 0.34 wt%, then that be 1.408?

Entire doc is attached, if you need to see more.

The API gravities of the resid oils 23.1 21.2 and 19.0
appear to be given and then the component's incremets of the resid are calculated from those APIs. Are they just well known common API values for those oils?

Entire doc is attached.
Thanks

Is it just that the goo in the bottom of the barrel seems to collect the sulphur elements?

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.
 
The S solubility depends on the MW of the oil.
See how little of it there is in the light fractions?
All of the S has to go somewhere.

Maybe I don't know what "whole" crude is. I thought that included the resid.
How is the total = 0.326
When right above it is 1.408
I'm very confused.

If you take the individual yield increments and multiply by their %S it should total up to 0.326%, because that is what that number is.
