Kettle Reboilers and Vaporizers Short Course

Course Fee: US$650

Thermal design methods for kettle reboilers and vaporizers have evolved over the years and some old rules-of-thumb no longer apply. New research results, software advances, and feedback from industry all contribute to improved design practices. The course presents the most up-to-date research in kettle design, provides our current recommendation to use Xist to model kettles accurately, and discusses future research and software development to improve predictions. Several example problems illustrate recommended good practices for using Xist, interpreting warning messages, improving designs, and troubleshooting cases.

Key Topics

• Shellside boiling methods
• Recirculation
• Liquid level and bundle dryout
• Differences between bundle composition and feed composition
• Kettle sizing
• Entrainment
• Vibration
• Fouling

Suggested Participants

Thermal design engineers and heat exchanger experts

HTRI Software
