Decoking process

A delayed coker is a type of coker whose process consists of heating a residual oil feed to its. That made it possible, by having two coke drums, for delayed decoking to become a semi-continuous process. A process for decoking a convection section of a furnace for cracking a hydrocarbon fee the furnace comprising a radiant section having burners that generate . A device for drilling a layer of coke within a reactor to effect the decoking of the reactor includes a decoking tool arranged at one end of a hose . A specially constructed decoking apparatus is provided to effectively and efficiently bore a pilot hole and ream the remainder of a bed of coke with a high . The furnace tube decoking pig has become the main means of removing deposits.

How the DDT Descaling Decoking Process Works. The DDT process begins after the completion of steaming out residual feedstock in the assigned heater. Eventually, the effects of various parameters such as air flow rate and initial bed temperature on decoking process have been studied entirely . A coked tube encourages more coke to accumulate. Need for decoking forces unprofitable downtime, often with unpredictable . This is part of a larger piece of animation created for a training video for an oil company.
