The petrochemical industry is pretty good at recovery, although their problems generally aren't caused by nature. I'm figuring that they should be able to get plants back on line about as quickly after this as they do after an explosion. I think a lot of folks are going to be surprised on how quickly some of the refineries come back on line. The biggest delay at some won't be in the damage repair, but in assembling and housing workers.
The port and related industry can be brought onstream rather quickly. It is the city that will be the problem.
Clearly, the choke point in the recovery will be workers and their housing.

Some of the refineries may be underwater. Maybe that should have no effect on bringing them online -- once the water recedes. I know the buildest hurdle is electrical power for refineries. I don't see why they don't build a small electrical generator facility onsite, and just pump diesel into the generator.
One of the refineries near Baton Rouge had trouble getting back online because the power grid was down.
I don't see why they don't produce their own electricity since they probably have diesel storage tanks at most refineries.
But I really don't know...
