Recid Line to Bottom Head to Shorten Coking Cycle
Many cokers have a removable spool piece between the bottom head of the coke drum and the resid feed line. This section of piping must be disconnected every cycle. Usually, it is not possible to drop the bottom head without going through this exercise. By designing the bottom-head removal carriage properly, this spool piece can be left permanently attached to the bottom head. This feature saves 10 minutes during the unheading operation and 20 minutes when the bottom head is replaced.
