  • Coking drum related method and apparatus
    Publication number: 20060254902
    Abstract: A safety system for a coking facility where there is a coke drum and a drill assembly. When the coke accumulates in the drum, a drill head of the drill assembly is lowered into the coke drum to emit high pressure water jets to remove the coke from the coke drum. There is a enclosing structure with an access door which is fixedly mounted at a location above an upper opening of the coke drum, so that when the drill head is moved out of the coke drum and there is an accidental jet water discharge, it will be redirected at a location within the enclosing structure. Interlock systems are provided.
