    Xist Workshop  (US$450)

    Instructor: 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, February 19 - Wednesday, February 20, 2019

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

    Instructors: S. Greg Starks and Tom Lestina

    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)

    Instructors: Salem Bouhairie and 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

Salem bouhairie

Senior Project Engineer, Research, earned his BEng, MEng, and PhD in Civil Engineering from McGill University, in Montreal, Quebec, Canada. While pursuing his graduate studies, he taught Water Resources and Hydraulic Engineering as an Adjunct Professor; Bouhairie also worked as a Laboratory Experimenter in open-channel hydraulics. Following his graduation, he became a Research Assistant at the university, gaining additional expertise with CFD in modeling fluid flows. He worked at Northwest Hydraulic Consultants, in Edmonton, Alberta, Canada, where he conducted physical hydraulic modeling investigations and river hydrology assessments. This experience gave him a broad-based knowledge of heat and mass transfer, thermal- hydraulic design, and computational methods. Bouhairie has delivered presentations on his work in Canada, the United States, England, and Brazil; his work has been published in the Journal of Fluid Mechanics and the Journal of Hydro-environment Research.
