Reply #2: I worked at that refinery for a few weeks in the 80's...

... when it was still owned by Shell.

Scary place. We were onsite to document the "nightshift engineering" that had taken place over the years. The process diagram was essentially in one guy's head - Elmer.

Elmer took us on a tour to explain how the plant actually worked;
"See that black spot on the ceiling over there? Four guys died here in 1972".
"See that steam pump over there? I remember when it blew up and destroyed everything in a 30' radius"
"If you hear steam escaping, stop in your tracks, and if you like your fingers, especially don't run your hand along the pipes to try to find it."
"Today we're climbing the crude column. If the wind shifts, you don't want to be downwind of the stack - hydrochloric acid. Here's your gas mask."
