::Paul, barg is "bar gauge". Bourdon tube pressure gauges display the pressure above atmospheric pressure. Thus, bar = barg + atmospheric pressure. 
::Just as engineers in the U.S. use psia and psig (meaning psia absolute and psi gauge), many if not most metric country engineers use bara and barg (meaning bar absolute and bar gauge). - [[User:Milton Beychok|Milton Beychok]] 09:54, 10 May 2008 (CDT)

barg

Milton what is barg? I know Pa, atm, and bar.--Paul Wormer 02:51, 10 May 2008 (CDT)

Paul, barg is "bar gauge". Bourdon tube pressure gauges display the pressure above atmospheric pressure. Thus, bar = barg + atmospheric pressure.
Just as engineers in the U.S. use psia and psig (meaning psia absolute and psi gauge), many if not most metric country engineers use bara and barg (meaning bar absolute and bar gauge). - Milton Beychok 09:54, 10 May 2008 (CDT)

slurry settler

In your diagram you have fuel oil go from the top of the slurry settler, but you write: The so-called clarified slurry oil is withdrawn from the top of slurry settler ... --Paul Wormer 03:00, 10 May 2008 (CDT)

fines

Are (or is) "fines" the same as "particulates"?--Paul Wormer 03:06, 10 May 2008 (CDT)

Finished reading

Milton, I found it interesting and have one or two questions (see above).--Paul Wormer 03:22, 10 May 2008 (CDT)
