A new anticoke technology sustains a noncatalytic layer on cracking tubes that reduces coking


For ethylene cracking furnaces, coking deposits severely reduce yields and shorten the run length. Coking is a side reaction from thermal cracking; its formation ultimately increases energy consumption since tube fouling decreases unit heat transfer. Other side reactions such as carbon monoxide (CO) formation must also be controlled to maintain process efficiency for downstream sections.
