  • Descrição: A survey of tower failures ranks kettle reboilers as the most troublesome reboiler type in the chemical process industries (CPI). Excessive pressure drop in kettle reboiler circuits is the prominent kettle malfunction, causing liquid to back up in the tower base beyond the reboiler return elevation. What is often unappreciated is that in many of the troublesome cases, entrainment plays a key role in tower base backup. The problem for troubleshooters is that until now, there have been limited literature reports of entrainment from kettle reboilers. Although one of the authors encountered cases where a kettle reboiler was hypothesized to behave like a thermosiphon reboiler, this is the first time where this behavior was actually monitored and demonstrated by comprehensive field tests. The key to preventing entrainment is to follow good design practices. The winner is the conclusive diagnosis and a good path forward towards a solution.
