Ethylene furnace radiant coil decoking method |
摘要 |
Methods are provided for decoking the radiant coils in an ethylene cracking plant. The decoking process is controlled by monitoring the coil outlet temperature to control the rate of burning of coke in the radiant coils. Air flow rates, steam flow rates and coil outlet temperatures are controlled during the decoking process to prevent tube damage, minimize decoking time and maximize coke removal.
