  • Minimizing coking problems in tubular process furnaces
    Patent number: 5283049
    Abstract: A closed tube extension or deadleg is included below the vertical tube of a hydrocarbon pyrolysis furnace. The deadleg passively collects spall coke particles to avoid plugging of the tube or its hydrocarbon inlet. Inspection or cleaning devices can be inserted through the deadleg into the tube and blocked tubes can be cleared. Pressurized steam and/or air can be injected through the deadleg to accelerate decoking of individual tubes.
