Units at refineries are routinely shut down for maintenance.
Just finished one such shut down at the Whiting refinery, on Monday.
5 units were shut down at the same time.
Though we have less physical refineries, than we had 20 years ago, our refining capacity has increased.
Ah...I had often read that the refineries are operating at higher and higher capacities (75-90%) so it is much more difficult to bring down capacity to do any kind of major maintenance.
Thanks for the info...I used to get a lot of info from a Freeper (dang I forget his name now) but he seemed to have a solid knowledge of the industry, and he stopped posting a while back...our loss, I think.
I hadn’t noticed the Whiting turnaround was complete. Good news!
