  • Publication number: 20060188417
    Abstract: System and method are disclosed for increasing the effectiveness of the lower tubes in a delayed coker furnace. The system and method involve arranging the tubes so that the lower tubes are as close to the heat source as the upper tubes. Such an arrangement allows all the tubes to have substantially the same amount of radiant flux. In some implementations, it is also possible to conform the refractory floor to the arrangement of the tubes.

  • Publication number: 20050098477
    Abstract: It has been discovered that the tubes within a radiant heating section of a coking furnace can be advantageously arranged differently than in a single vertical column and connected together in a simple, planar serpentine pattern. By arranging the tubes in a plurality of offset or staggered vertical columns, the same number of tubes can be contained in a shorter vertical space with savings in the size of the coking furnace. This arrangement permits the upper tubes to be closer to the radiant heat source thus making the heating of the feedstock more efficient, and also allows the tube bends connecting adjacent tubes to be of greater radius, meaning that the pressure at which the feedstock is passed through the tube bundle can be lower allowing more vaporization of the cracked process fluids. The tendency for coke to deposit on the interior walls of the tubes is reduced, increasing operational availability and lowering maintenance costs for cleaning out the tubes.
