HTRI Training - Global Headquarters

Navasota, Texas, USA | January 22 - 25, 2018

Registration Deadline:
January 19, 2018

Join us at the HTRI Global Headquarters in Navasota, Texas, USA, for four days of hands-on, case-based training. During this training event, we will discuss heat exchanger selection, geometry, design, and troubleshooting while using HTRI Xchanger Suite software to test your knowledge.

The training schedule includes three courses, all taught by HTRI experts:

  • Xist Workshop
  • Process Heat Exchangers: Applications and Rules-of-thumb Short Course
  • Xace Workshop

Training Courses

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

Course fees include arrival tea/coffee, lunches and snacks at breaks, training materials (workbooks, solutions booklets, and electronic copies of the case files), and computers with Xchanger Suite.

    Xist Workshop (US$450)

    Instructors: Patrick S. Redmill and S. Greg Starks

    Even if your work is limited to shell-and-tube heat exchangers, there’s much to be learned! This workshop is devoted to the geometries handled only by Xist. The day focuses on the extensive options available in Xist and how you can use these methods effectively to solve several example problems. You will leave the class knowing how to take full advantage of the features this robust tool offers.

    Key Topics

    • Overview of Xist capabilities and applications
    • Geometry input for shell-and-tube heat exchangers
    • Process specifications for rating, simulation, and design
    • Guidelines for specifying fluid properties
    • Introduction to vibration analysis

    Suggested Participants

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

Tuesday, January 23 - Wednesday, January 24, 2018

    Process Heat Exchangers: Applications and Rules-of-Thumb Short Course (US$1200)

    Instructors: Niki Ritchey and S. Greg Starks

    Why select a horizontal instead of a vertical thermosiphon? How do you size a heat exchanger for an application? How much margin should you select? What are typical operating problems?

    This course focuses on developing design checklists and rules-of- thumb to help engineers avoid common problems in process heat transfer. It surveys common heat exchanger types used in the process industry including shell-and-tube, air-cooled, plate-frame, and plate- fin exchangers. Fundamentals of heat transfer and pressure drop are provided for single-phase, boiling, and condensing services. Selection criteria for common applications are discussed, guidelines for thermal design are provided, and detailed examples are summarized. Industry case studies of thermal design and operational problems are presented and lessons learned discussed.

    A copy of Process Heat Transfer: Principles, Applications, and Rules of Thumb, by Robert Serth and Thomas Lestina, is included with the course and serves as the primary reference for course material. Engineers who have recently graduated and more experienced engineers who are responsible for design and operation of process heat exchangers will find this course valuable.

    Key Topics

    • Types and applications of heat exchangers
    • Fundamentals of heat exchanger performance
    • Heat exchanger selection criteria
    • Single-phase applications and performance
    • Boiling applications and methods
    • Condensing applications and methods
    • Operational problems
    • Troubleshooting heat exchanger operation

    Suggested Participants

    Engineers—from novice to expert—who want to improve their design process and checklists

    Xace Workshop (US$450)

    Instructor: S. Greg Starks

    Do you design only air-cooled heat exchangers? Evaluate their performance? Then this workshop is for you. Unlike the Xchanger Suite workshops, this course focuses only on air-cooler geometry. 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
