Reboiler Troubleshooting Short Course

Course Fee: US$650

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.

Upcoming Instructors

  • 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.


  • Li Anne Choong


  • Regional Sales Manager, Southeast Asia, has experience not only in sales but also in project management, business development, technical support, and training. Prior to joining HTRI, she worked as an Application Engineer, Product Manager, and Regional Support Manager for EDS Asia Sdn Bhd in Petaling Jaya, Malaysia, and as an Applications Engineer for Transwater Tenaga Sdn Bhd, Shah Alam, Malaysia. For the last six years, Choong has been marketing HTRI products and services in Southeast Asia; she will continue in this role, as well as provide training and technical support to members in the region. Choong holds a BEng in Chemical and Process Engineering from the University of Sheffield, Sheffield, United Kingdom.


  • Kevin Farrell


  • Principal Engineer, Computational Simulation & Validation, graduated from Pennsylvania State University, State College, Pennsylvania, USA, with his BS, MS, and PhD in Mechanical Engineering. His areas of expertise include fluid dynamics, vibration, and thermal engineering. His responsibilities at HTRI focus on flow- induced vibration, computational fluid dynamics (CFD), visualization studies, and fired heaters. Prior to joining HTRI, he worked for 16 years as a researcher and deputy head of the Fluid Machinery Department of the Applied Research Laboratory (ARL) at Pennsylvania State University. A member of ASME and ISA, Farrell is a licensed Professional Engineer (PE) in Pennsylvania and Texas.


  • David Frankum


  • Senior Engineer, Technical Support, provides technical support and training for HTRI. He earned a BSc in Mechanical Engineering from the University of Birmingham and a PhD in Chemical Engineering from the University of Nottingham. Before joining HTRI, Frankum worked for Aspentech as a Team Leader in technical support. He also has experience with UKAEA as a technical/quality manager in the separation processes service. Frankum’s research experience, along with his knowledge of a wide range of heat exchanger-type equipment and design software packages (EDR, HTC, B-JAC, HYSYS, Aspen plus, and Xchanger Suite), gives him a broad-based skill set for his role at HTRI.


  • LiDong Huang


  • Principal Engineer, Experimental Research, holds a BS from Shanghai Maritime University and an MS from University of Shanghai for Science and Technology, Shanghai, China. He received his PhD in Mechanical Engineering from the University of Houston, Houston, Texas, USA, where he studied and developed methods for predicting subcooled flow boiling, film boiling, and critical heat flux. Before joining HTRI, Huang worked as an instructor and thermal engineer in the Department of Marine Engineering at Shanghai Maritime University. Since joining HTRI, he has focused primarily on boiling and two-phase flow phenomena but also has done some experimental and analytical work on plate heat exchangers, organic fouling, and single-phase mixed convection. Huang has taught numerous courses for HTRI. He is a member of ASME and a licensed Professional Engineer (PE) in Texas.


  • 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.


  • Andy Mountford


  • Senior Consulting Engineer, Technical Services and Sales, provides technical support and training for HTRI. He earned a BSc and MSc in Chemistry and a PhD in Organometallic and Materials Chemistry from the University of East Anglia, Norwich, UK. During his tenure there, he conducted research at Wolfson Laboratory for Materials and Catalysis. He previously held the position of Thermal Design Supervisor at Tecnicas Reunidas in Madrid, Spain, gaining valuable experience using HTRI methods and software. Mountford oversaw the development of several high-profile PWR and BWR nuclear plant projects, as well as gained valuable experience in the thermohydraulic design of heat transfer equipment for the petrochemical and nitric acid/nitrates industries. His experience in using HTRI Xchanger Suite makes him uniquely qualified to bring an end-user’s perspective to the HTRI training program and to share techniques for effectively working with the software.


  • S. Greg Starks


  • Director of Sales, Americas, graduated with a BS in Mechanical Engineering from Texas A&M University, College Station, Texas, USA. While working at the Shuttle Support Thermal Control Systems Analysis Group of Rockwell International, Houston, Texas, he performed thermal analyses for the space shuttle and developed geometry models for the shuttle/space station. From 1994 – 1999, Starks was employed at HTRI, developing calculation engines for our software as well as a quality control database to track program changes. He then moved to Austin, Texas, to work as the Software Engineering Manager for Tanisys Technology, Inc., a supplier of automated test equipment for semiconductor memory technologies. When he rejoined HTRI, Starks was responsible for enhancements to the Xist calculation engine. He now leads sales efforts in the United States and Canada and assists with HTRI’s training initiatives.
