  • Safely preparing a coke drum for decoking would involve the following steps: (1) removing the working surface opening cover, if present, creating an opening in the working surface for the coke to pass; (2) remotely aligning and engaging a closure mover to the drum-bottom closure; (3) remotely energizing the drum-bottom closure to the coke drum; (4) remotely unlocking, disconnecting and separating the coke drum from the inlet pipe; (5) remotely unlocking the drum-bottom closure from the coke drum; (6) remotely disengaging the drum-bottom closure from the coke drum in a controlled manner; (7) remotely removing the drum-bottom closure from the opening in the bottom of the coke drum; (8) remotely producing and securing a passageway between the bottom opening of the coke drum to or about the opening in the working surface; (9) remotely unlocking and moving the drum-top closure from the opening in the top of the coke drum; (10) lowering the drill bit into the coke drum through the opening in the top of the coke drum; and (11) remotely engaging a drilling head or possibly
  • Safely and efficiently preparing a decoked coke drum for coking would involve the following steps: (1) remotely replacing, aligning and locking the drum- top closure to the coke drum once the drill bit is removed from the coke drum; (2) remotely decommissioning the decoke chute and replacing the working surface opening cover; (3) remotely aligning and locking the open ends of the inlet piping together, which reconnects the coke drum to the inlet pipe; (4) remotely replacing, aligning and locking the drum-bottom closure to the opening at the bottom of the coke drum.
  • the aperture is opened to allow material exiting the coke drum to pass through the working surface and is closed so that workmen cannot pass though.
  • An exit chute can be deployed and undeployed through this aperture from the working surface to the bottom of the coke drum forming a passageway for guiding material out of the vessel.
  • the present invention provides a unique and safe system to open and close the aperture and deploy and undeploy the exit chute.
  • the present invention also applies, in combination, the open and closing of the aperture and the deploying and undeploying of the exit chute.
  • gaskets requiring joint contact surface compression and/or seating force can be energized between the flange members creating a seal barrier to seal the vessel's internal environment from its external environment.
  • Stored energy in the clamp segment fastening device secures a leak tight joint.
  • one of the conical make-up shoulders is replaced by a substantially straight non angled make-up shoulder, such as that disposed on manually bolted flanges like those described by ASME B16.5.
  • This arrangement allows an existing manually bolted flange to be retrofitted for remotely controlled operation by removing the manual bolts and disposing the present invention about an existing flange.
  • an existing manually sealed flange pair will have been disposed on a pair of structural units to be joined. Hazardous conditions of or about the joining of this flange pair or the benefit of decreased joint connecting and/or disconnecting time gives birth to the need for remotely controlled devices, such as the
  • the design of the present invention's flange retaining clamp allows for dry assembly of the component parts of the clamp. That is, no grease or other lubricant is required during assembly. Further, depending upon the material from which the components are manufactured, the present device can be utilized in environments up to 1800 F.
  • FIG. 1 is an elevation view of a vertical vessel with a preferred embodiment of the present invention having flange retaining clamps attaching sections of a vertical vessel.
  • FIG. 2 is a partial section view similar to FIG. 4, illustrating a preferred embodiment of a self-aligning feature for the flange members. Bolts 8 are rotated in view from their true position.
  • FIG. 5 is a section view of the contracted position of a preferred embodiment of the present invention as seen along the lines 1 — 1.
  • FIG. 5 shows the top plan view of the automated flange retaining clamp partially sectioned. For clarity, FIG. 5 has a clamp support bracket radially removed from its true position by distance 6.
  • FIG. 33 is an elevation view of a preferred embodiment of the inlet pipe connecting system. The view illustrates connector 63 in the coking (joints closed) position.
  • FIG. 41b is an elevation view, partially sectioned, of a preferred embodiment of the centralizing flange of FIG 41a.
  • force adjusters 176 can also be inco ⁇ orated with connectors similar to FIG. 4.
  • springs 39 hold locking devices 33 from moving when the remotely actuable powered locking device actuator 41 is disconnected from the power source.
  • the springs 39 contribute to moving the locking device 33 into locking position when the remotely actuable powered drive member 27 has created sufficient clearance between the clevis nut 24 and the locking device 33.
  • the locking device 33 is a positive locking element that locks the stored energy into clamp segment fastening device 55 without relying on friction or a power supply to maintain the stored energy.
  • the motion allows closure mover 61 to translate flange member 5 vertically upward and downward.
  • the vertical movement allows flange member 5 to move relative to stationary vessel 56.
  • This allows flange member 5 to be lowered sufficiently so that flange member 5 can clear connector 62.
  • Elevator 61c can be designed such that it can force flange member 5 against vessel 56 with enough force to overcome the loads imposed on flange member 5 by the contents of the vessel 56. This causes a sealing barrier to be imposed between flange member 5 and flange 10 disposed on vessel 56.
  • actuator 65 is remotely activated to power movement of exit chute 59 in the vertical direction.
  • Actuator 65 is attached to exit chute 59 at location 66 and to working surface 107 at anchor 70.
  • An embodiment inco ⁇ orates hydraulic cylinders as actuator 65.
  • the actuator 65 could be any plausible actuator having different benefits, such as a cable or chain wench.
  • Closure mover 113 is disposed on vessel support deck 105 by base 129.
  • FIG. 24, FIG. 25 and FIG. 26 show closure mover 113 in a lowered position indicative of allowing flange member 5 to clear connector 62 as it is moved away from the longitudinal centerline of vessel 56 by actuator 148.
  • FIG. 27 and FIG. 28 show the opposite raised position of closure mover 113.
  • FIG. 25 and FIG. 28 are substantially similar, as well as, FIG. 24 and FIG. 27.
  • Thermal transients take two forms, heatup relative to time, and cooldown relative to time. Each form presents different problems.
  • at least two elements are conduit elements ("conduits") adapted to retain a substance, which commonly is the genesis of the thermal transient.
  • Other elements of the connector (“preloading elements") are adapted to engage the conduits creating seal integrity.

Abstract

Ce dispositif permettant d'exploiter à distance une enceinte comporte un mécanisme de transport d'organe d'obturation servant à retirer un organe d'obturation d'enceinte d'une ouverture ménagée dans une enceinte, un raccordement de joints possédant des organes d'assemblage permettant de sceller et de desceller l'enceinte et un système de déchargement servant à vider l'enceinte des matières qu'elle contient. Les organes d'assemblage, qui comprennent plusieurs éléments de fixation, sont à l'état activé au moment du stockage d'énergie et à l'état de repos lorsqu'aucune énergie n'est emmagasinée. Cet état activé est associé à une première ou à une seconde position, l'état de repos étant associé à l'autre position. Les éléments de fixation sont conçus pour s'adapter à des attaches et être connectés par celles-ci, ces attaches, qui comportent des sous-ensembles d'attaches, étant conçues pour être verrouillées aux fins du stockage d'énergie dans les organes d'assemblage. Ces organes d'assemblage sont connectés de telle sorte qu'une défaillance d'un seul sous-ensemble ne suffise pas à les séparer ou à mettre le système hors d'état de fonctionnement. Ce système comporte également un ou plusieurs mécanismes d'entraînement actionnés destinés à apporter de l'énergie aux organes d'assemblage et conçus pour activer au moins une partie des attaches.
