The present subject matter describes a method and apparatus for operating a delayed coker. The method comprises contacting a vapour produced in a delayed coker-drum with a catalyst maintained in form of a bed, and maintaining a level of said catalyst-bed within pre-defined limits during catalytic-cracking of the vapour. Thereafter, the cracked-vapour is routed to a coker-fractionator column to trigger conversion into one or more hydrocarbon products.

The provided is a novel heat-induction decoking device and method tailored for the thermal conversion of solid fuels. The efficient heat-induction decoking device for the thermal conversion of the solid fuels includes: a decoking tank body, which is configured to condense a macromolecular tar in a pyrolysis gas and discharge the condensed tar from a bottom to a tar tank for storage; an electromagnetic induction heating system, which is disposed on an outer wall surface of the decoking tank body to heat the outer wall surface of the decoking tank body; an ultrasonic vibration decoking system, which is disposed on the decoking tank body to enable the decoking tank body to generate vibration by ultrasonic wave so as to enhance tar fluidity. This innovative design not only reduces energy consumption and equipment wear but also extends system operational lifespan, thereby offering substantial improvements in economic and environmental sustainability.

A closed system for gaining sellable petroleum coke pieces out of solidified petroleum coke in a coke drum unit, comprises a coke drum unit containing solidified petroleum coke; a coke crushing unit for crushing petroleum coke into sellable petroleum coke pieces; a closed slurry pipe leading petroleum coke slurry to a closed slurry pit; a dewatering bin unit for receiving petroleum coke slurry from the slurry pit, for collecting the sellable petroleum coke pieces and for leading filtered water and petroleum coke fines out of it; a closed drain water pit, separate from the slurry pit, for receiving the filtered water and the petroleum coke fines from the dewatering bin unit; a water settling tank receiving the filtered water and the petroleum coke from the drain water pit and for separating the petroleum coke fines from the water such that the petroleum coke fines collect in the bottom part of the water settling tank, and for leading the petroleum coke fines into the slurry pit where they mix with the petroleum coke slurry; a clean water tank for receiving the purified water from the upper part of the water settling tank; and a removal unit for removing the sellable petroleum coke pieces from the dewatering bin unit.
