HTRI Training - Europe

Check-in begins at 8:30 AM. Courses run from 9:00 AM to 5:00 PM daily.

Course fees include arrival tea/coffee, lunches and snacks at breaks and training materials (workbooks, solutions booklets, and electronic copies of the case files). Computers with Xchanger Suite are available for use during the training event. Computers may be shared with other attendees.

Special Topics in Xace Short Course  (US$650)

Instructors: Andy Mountford and Salem Bouhairie

Improve your understanding of the methods in Xace and develop new skills to model difficult cases. This short course focuses on improving thermal predictions, interpreting results, troubleshooting cases and applying workarounds. Even the most experienced thermal designers will gain new insight into how to improve thermal analyses using Xace.

Case studies include:

• Rating natural draft (fans-off) cases
• Improving accuracy of predicted driver power
• Modeling units with redundancy fans (3x50% fans)
• Multiple service units

Suggested Participants

Experienced Xace users who rate, design and troubleshoot air-cooled heat exchangers

Course credits: 6 hours (PDH/CEU)

Heat Exchanger Troubleshooting Short Course  (US$650)

Instructors: Andy Mountford and Salem Bouhairie

Design decisions can have a costly impact on heat exchanger operation. In this course, you learn by reviewing several real cases in which unit designs had critical commercial consequences for operators/ owners. Among other topics, this course may address

• assessment of acoustic vibration in rectangular ducted bundles (Xace^®)
• vibration analysis of a shell-and-tube heat exchanger (Xist^® and Xvib^®), including a review of the velocity scaling applied to tubes near impingement plate edges
• sizing of annular distributor (vapor belt) and associated tube vibration analysis (Xist and Xvib)
• root cause analysis of tube failures in a steam generator (a reboiler/steam drum configuration modeled as a thermosiphon reboiler in Xist)
• design review of an air-cooler/condenser (Xace) with excessive tubeside pressure drop during winter operation

In some cases, the units did not work in service; in others, the designs were revamped before the units began operation. Each case study is introduced as a problem; participants work individually or in groups to determine the cause and develop solutions. Prior to each case, the instructor reviews related HTRI methods. 

Suggested Participants

Engineers—from novice to expert—who want to ensure that design problems are identified before operation

Course credits: 6 hours (PDH/CEU)

Condensers Short Course  (US$650)

Instructors: Andy Mountford and Salem Bouhairie

Learn the fundamentals of condensation mechanisms and how they apply to condenser design! Apply guidelines to develop Xchanger Suite cases for accurate assessment of performance. This course provides a foundation for understanding the basis for thermal design of typical industrial heat exchangers.

Key Topics

• Film condensation of pure components
• Relationship between pressure drop and saturation temperature
• Condensing flow regimes: Vertical units/Horizontal units, tube side and shell side
• Specifying pure component condensers in Xist
• Noncondensables and mixture condensation
• Specifying mixture condensers and inerts in Xist
• Vapor phase coefficient
• Desuperheating and subcooling
• Bulk-equilibrium vs. two-layer subcooling model
• Venting inerts
• Drainage
• Baffle design in condensers
• Condensation with enhanced heat transfer surfaces
• Vacuum condenser design challenges

Suggested Participants

Engineers who design and evaluate condenser equipment

Course credits: 6 hours (PDH/CEU)
