RTC update: Improvements to Prototype Test Unit (PTU) expand research potential
September 11, 2023
At our Research & Technology Center (RTC), we perform research that improves the accuracy of our methods and software, as well as contract testing for external clients. We recently used the PTU for turndown and performance testing of thermosiphon reboilers. Upcoming research includes experimental observations of full or partial differential condensation in...

BG1-19 Heat Transfer and Pressure Drop in Vertical Tubeside Thermosiphon Reboiler Under Turndown
June 10, 2020
This report summarizes HTRI data on vertical tubeside boiling, highlighting the shortcomings of current methods in accurately predicting tubeside pressure drop and heat transfer at low mass velocities. Improvements to the liquid holdup model and a warning message for thermal prediction close to turndown conditions are also discussed. When implemented in...

Research Update: Guidelines for Vertical Tubeside Thermosiphon Reboiler Turndown
May 28, 2020
Thermosiphon reboilers often pose challenges for column operations in refineries and chemical processing plants. Some challenges are related to turndown, when reboiler circulation rates or duties are lower than design conditions. The process industry uses various checklists and criteria, though most guidelines have little to no validating data backing them up....
