Engineering Practice: Get More From Vertical Thermosiphon Reboilers
| By Omid Zadakbar, Ali Vatani and Kianoosh Karimpour University of Tehran
A very common heat exchanger in the chemical process industries (CPI) is the vertical thermosiphon reboiler (VTR; Figure 1). Due to size and fluid-flow restrictions, however, its heat transfer rate is often quite low. The subcooled region formed at…
