You will leave the class knowing how to take full advantage of the features this robust tool offers.

Key Topics

  • Overview of Xist interface and the benefits of HTRI methods
  • Process specifications rules for rating, simulation, and design
  • Guidelines for specifying fluid properties
  • Description of Xist geometry input parameters and their defaults
  • Interpretation of Xist outputs for validation of unit performance

Suggested Participants

Designers of shell-and-tube heat exchangers and process engineers who evaluate their 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)

Learn how to use Xace effectively to rate and design air-cooled heat exchangers, economizers, and air preheaters. All example problems and practice exercises relate to geometries handled only by Xace.

Key Topics

  • Overview of Xace capabilities and applications
  • Geometry inputs for air coolers and economizers
  • Process specifications for rating, simulation, and design
  • Guidelines for specifying fluid properties
  • Introduction to HTRI analysis methods

Suggested Participants

Designers of air-cooled heat exchangers and process engineers who evaluate their performance

HTRI Software

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

Heat Exchanger Troubleshooting Short Course  (US$650)

Instructors: Patrick Redmill, Samuel Bajomo, Rajan Desai and Andy Mountford

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

HTRI Software

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

Course Credits: 6 hours (PDH/CEU)

Xfh Ultra Workshop  (US$450)

Instructors: Patrick Redmill, Samuel Bajomo, Rajan Desai and Andy Mountford

This workshop is an introduction to modeling the performance of process fired heaters using Xfh Ultra. Starting with a brief review of fundamental concepts, attendees will then use an API 560 Specification Sheet of a proposed fired heater design to develop a complete fired heater model in Xfh Ultra and rate the heater’s performance.

Key Topics

  • Process fired heater fundamentals
  • Xfh Ultra capabilities and applications
  • Heuristic approach to model development in Xfh Ultra
  • Fluid definitions, process specification, and geometry inputs
  • Practical guidelines for interpreting Xfh Ultra output reports and measures of performance

Suggested Participants

Engineers with or without prior knowledge of fired heater design, who rate the performance of process fired heaters

HTRI Software

This course will make use of the following HTRI software: Xfh® Ultra. All training materials are based on the current software version.

Course Credits: 6 hours (PDH/CEU)

Samuel Bajomo
Samuel bajomo

Senior Heat Transfer Specialist, Engineering Services, completed his BEng, MSc in Mechanical Engineering at University College London, London, United Kingdom (UK), majoring in Materials Science and Structural Mechanics. He began his career with MW Kellogg working on mechanical design of pressure vessels and heat exchangers and later transitioned into the heat transfer group as Principal Heat Transfer Engineer. In 2012 he moved to Wood Plc, London, UK where he oversaw the thermal and mechanical design of heat exchangers and fired equipment for several major oil and gas and petrochemical projects. His experience spans front-end engineering design (FEED), requisition, detailed engineering, and oversight of equipment manufacture. Bajomo then operated as an independent heat transfer consultant, working with equipment manufacturers and end-users on a wide variety of troubleshooting and design verification projects. His exchanger design and practical industry experience brings a uniquely qualified contractor’s perspective to HTRI’s Engineering Services team. Bajomo also currently serves on the board of the Institution of Mechanical Engineers (IMechE), Pressure Systems Group, and is a CEng MIMechE.
