to help out, I've been eating chili a couple times this week with some extra beans. Hi-fiber cereal, a microwave burrito bowl from TJs, and a fried chicken sandwich just to upset my digestion. Going light on the extra fiber wheat bread, but that'll be tonight. Maybe some chickpeas.
But seriously, restart is always complicated in any industrial operation. Accidents occur most often on restart and shutdown. I'd imagine the pumps that keep the stuff moving, and refilling the breakout tanks, will be the things that could go wrong. Maybe a pressure fluctuation in the pipe.
