Reboiler Troubleshooting Short Course

Course Fee: US$650

Download Course Details

Reboilers are arguably the most troublesome auxiliary components in a distillation system. Reboiler failure or underperformance can lead to column malfunction and/or shutdown with severe economic consequences. In many cases, problematic operation can be identified and avoided in the design phase by correctly modeling the units in Xist, but this is contingent on the user’s ability to specify and interpret such cases. Attend this short course to practice modeling and review challenging reboiler designs in Xist through a series of interactive case studies.

Suggested Participants

Xist users who design, troubleshoot or evaluate reboiler performance

HTRI Software

This course will make use of the following HTRI software: Xchanger Suite® component Xist®. All training materials are based on the current software version.

Course Credits: 6 hours (PDH/CEU)

  • Peter Joosten


  • Senior Consulting Engineer & Regional Sales Manager, Australia/Oceania, works with HTRI’s Engineering Services and Global Sales teams. His principal responsibilities include developing and conducting training programs, providing technical support, and promoting membership in the HTRI consortium. He earned a Bachelor of Mechanical Engineering degree from Fontys University of Applied Science, Venlo, The Netherlands. Prior to joining HTRI, Joosten was a Senior Heat Transfer Engineer at W. E. Smith Engineering, Coffs Harbour, Australia. His primary role was the thermal design and analysis of all types of shell-and-tube exchangers, air coolers, economizers, feedwater heaters, and steam surface condensers. He was also responsible for the mechanical design and stress analysis of these units, as well as for analyzing and resolving operational issues. His previous experience with HTRI software gives him a valuable end-user perspective.
