THERMOSIPHON REBOILER

To help you better use Xist to model thermosiphon reboilers, this webinar begins with an overview of thermosiphon reboiler operations. Next, we discuss design rules-of-thumb and Xist input guidelines, including reboiler inputs and piping. The webinar concludes with helpful hints for interpreting results by focusing on troubleshooting error messages....

Vertical shellside boiling is used for a variety of applications, including vertical thermosiphon reboilers where hot fluid must be on the tubeside steam generators/waste heat boilers, which use very hot or corrosive fluids as the heating medium vertical feed-effluent exchangers, whose vertical orientation prevents phase separation Ideal vertical shellside reboilers have...

In a vertical tubeside thermosiphon reboiler (VTTR), Ledinegg instability can occur when the tubeside pressure drop decreases with increasing flow rate. Theoretical analysis of two boundary conditions—constant heat flux and constant steam pressure—revealed that for either condition, Ledinegg instability can occur in a VTTR only when intube frictional pressure drop dominates...

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...

This report provides a comprehensive look at the turndown operation of a vertical tubeside thermosiphon reboiler (VTTR), including predictions of thermal and hydraulic performance and quantitative criteria for turndown limits. Data were collected for water, n-pentane, p-xylene, and n-pentane/p-xylene mixtures in an industrially relevant VTTR flow loop. The unit was systematically turned...
