They bought the old Crown refinery for $350MM in 2019 from Petrobras. Very familiar with the operation and maintenance and have lots of cost cutting horror stories. They paid way too much IMHO.
And now "The FCC was shut on June 1 by a malfunction that knocked the unit out of operation." and “We're leaning towards a hydroskimming focus in that regard,” .
If you understand refineries, the major money-making component of the operation is the FCC. Sounds like the FCC (an old modified Texaco Unit) was severely damaged and its not worth repairing, so with the FCC gone (and also losing cheap feedstock for the Alky), the refinery profitability and value plunges.
I expect this refinery to be sold at a loss or shuttered/converted to a tank farm terminal like Perth Amboy (defer environmental liabilities ). The "hydroskimming" is a good way to cut losses on a bad deal.
