BG1-20 Shutdown Heat Flux for Vertical Tubeside Thermosiphon Reboilers
December 18, 2025
This report reviews shutdown data and criteria for a vertical tubeside thermosiphon reboiler (VTTR) documented in a previous report. A new correlation for the shutdown heat flux is proposed. This correlation uses the vaporization duty, applicable to both pure component fluids and mixtures, to bridge the gaps that the previous correlations...

Demystifying thermosiphon operation
June 05, 2019
Siddharth Talapatra, Group Lead, Research Engineers focused on the thermal and hydraulic aspects of heat exchangers sometimes forget that exchangers do not operate as standalone units. A thermosiphon reboiler is one application where understanding the flow loop around the heat exchanger is vital. Essential to refineries and chemical processing plants, a...
