vt - Once more the Rockman must apologize for letting group down by making bad assumptions. Such as thinking everyone here understood how a refinery works. But you got me thinking many may not; that they don't understand that
the last time crude oil was used to run the US refining process was 1999 and then only used 10,000 bbls FOR THE ENTIRE YEAR.https://www.eia.gov/dnav/pet/PET_PNP_CA ... _NUS_A.htmFor 2015:
By far the largest energy source used to refine crude oil is NG: 850,000 million cuft. Still gas is a distant second 230,000 million cuft. And for those who don't know what "still gas" is: "Any form or mixture of gases produced in refineries by distillation, cracking, reforming, and other processes.
The principal constituents of still gas are methane and ethane. Still gas is typically consumed as refinery fuel or used as petrochemical feedstock." Most important: still gas does not contain the longer hydrocarbon chains that make up motor fuels and most of the other products.
The only other significant fossil fuel used in the process is "Catalyst Petroleum Coke": " In petroleum coker units, residual oils from other distillation processes used in petroleum refining are treated catalytically at a high temperature and pressure leaving the petcoke after driving off gases and volatiles,
and separating off remaining light and heavy oils. .
IOW chains that might be mixed in with the other liquid portion of the distillation process." So again I must apologize since I seldom read much of the details about a model that lacks any relevance to the petroleum industry where I've been employed for the last 4 decades.
But: "So Shorties numbers are off by a factor of 40 percent. That's really rigorous ."
So how many here didn't understand that no portion of the energy used to make gasoline, diesel and most of the other products actually came from the crude oil itself? For you I sincerely regret not having presented the actual EIA numbers linked above that proves that FACT.
