    On a four drum coker, has anyone considered the coke drum relief case based on a coke drum foam-over that plugs the vapor line or Fractionator?  The worst case scenario that I can think of is while two drums are coking and one drum is quenching, a coking drum carries over and plugs the vapor line and/or Fractionator.  Does anyone have a design basis for coke drum relief given this consideration?
