Heading Up

As soon as the cutting water pump is shutdown, the decoking crew immediately begins replacing the top and bottom heads. Both heads must be worked on simultaneously. Flange surfaces are prepared while the coke cutting is in progress. On this basis, heading up the coke drum and reconnect­ing the resid feed line takes about 30 minutes, assuming the last section of resid feed-line piping is integral with the bottom head.
