250,000 bpd is a healthy sized crude unit. The problem isn't so much the gasoline or Diesel that comes from the crude unit, but rather the downstream units that take the fractions from the crude and turn them into other products. Only a very small amount of what comes off of the crude goes directly to gasoline or Diesel. Most of the fractions will go downstream to other units using catalysts, etc to turn the feeds into something more useable. Most downstream units can run off of stored feed, if it is available. Most refineries don't have a bunch of storage allocated for downstream unit feedstocks though, as the bulk of storage is for crude, and finished blendstock. If they have pipeline or ship access, they may be able to purchase feeds from outside sources, but otherwise, the downstream units will only run for a short time before their feed inventory is gone and they **** down as well. That sucks, but it is better to see they shut down to repair a leak, than to rebuild a unit that blew up.
Nope. The Texas City refinery is just down the road a bit, so it definitely made headlines here. We'll see if anything is different now that Marathon owns it. Part of that issue was the use of outdated equipment. Part of it was the operating philosophy of management. A large contributor though was operators not recognizing an issue before it became a problem, and working to resolve it. Like other trades, there are operators who understand the process and can truly run it, but most of them memorize routines, and don't know how to recognize or react to the non-routine.
A little excitement yesterday when a pump locked up on one of the big units and almost shut down the entire process, but we safely recovered after a couple hours of fighting it. So far, today is a bit more relaxing. You?
