Here is Reuters article looking at US Refinery Closure Risk based on ranking of Import Crude Sulfur Processing Ability (Table shows 124 sites & Import Crude Bbl & Sulfur level – so its not complete list US Refineries). Points out why COP Trainer & other PA refineries were high on list for closure even though they were coastal & had access to good demand markets.
This of course is too simplistic approach – while it is significant factor that somewhat encompasses the refinery complexity level (Simple/Cracking/Coking-Complex), it doesn’t address size (-100MBD more at risk than +150MBD) or regional location (inland vs coastal) and several other factors. (Note Attached is PDF table in case issues with Reuters link.)
