Hello,
Our coker drums are unheaded manually on top and bottom. We are looking at the top unheading/heading operation and want to mitigate the ergonomic issues associated with head removal and installation.
Ergonomic Issue -> Our top drum flanges are are about 12″ above the deck and the operators are constantly bending over with a impact gun to remove or install the bolts for the top head removal or installation.
Hazard -> In addition we want to address a potential hazard when the top head is removed and we have a open drum top 12″ above the deck until the stem is lowered into the drum. The same is true after the cut of coke is complete and the stem is removed from the drum prior to the head being placed on top of the drum.
Obviously the Delta or Enpro Valves will provide the answer for these issues at a large cost.
What other means have refiners taken to mitigate the ergonomic and hazard issues on the top head deck?
Any and all responses will be greatly appreciated.
