Info

Typical Steam Cracking Furnaces Total Number of cracking tubes about 600 Total Reaction Volume about 45 m³ Total firebox volume about 9,000 m³ Residence Time 0.25 to 0.75 s Firebox Efficiency about 65%
Steam function and process limitation Enhance heat transfer Reduce coke formation and deposition Improve selectivity towards ethylene Operation purposes Coke deposition is the main process limitations due to: - High tube skin temperature - High pressure drop
