Kettle Reboilers and Vaporizers Short Course  (US$750)

Instructors: Andy Mountford and Ashley Hinojosa

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.

Designing Exchangers for Waste Heat Recovery Short Course  (US$750)

Instructor: Tom Lestina

Recovering and reusing waste heat in heat exchangers can reduce overall energy costs. A renewed emphasis on sustainability has refocused attention on improving existing design practices for heat exchangers. This course critically examines thermal design practices of waste heat recovery equipment and identifies potential improvements. After a review of the fundamentals of thermodynamics, the course addresses how the second law impacts waste heat recovery efficiencies. The challenges to improving heat recovery practices are discussed for a variety of process applications: reformer feed-effluent streams, wet crude pre-heat, gas turbine recuperation, and low temperature economizer designs. Participants will learn practical performance limits for current design practices and discuss where improvements in heat exchanger technology can improve efficiencies. The course leverages discussions at the 2024 Horizons Symposium.
