BK1-19 Transition and Film Boiling Methods for Kettle Reboilers
November 21, 2022
This report proposes several correlations based on physical properties to replace the current reduced-pressure correlations Xist® 9.0 uses to determine the maximum heat flux and film boiling heat transfer coefficient for kettle reboilers. It discusses methods to determine the critical temperature differences and documents a new transition boiling method that improves...

BK1-18 A Parametric Study of Entrainment Using CFD Simulations
November 10, 2022
Accurate prediction of kettle entrainment is crucial for sizing kettles effectively, reducing equipment cost, and increasing column efficiency. Operating experience has informed the development of simple sizing rules. Two-phase CFD models can compute the amount of entrainment directly from the governing equations of motion. Two computational approaches are demonstrated: one uses...

BK1-17 Improvements to HTRI 1D Kettle Circulation Model
October 18, 2022
This report discusses bundle pressure drop and recirculation flow rate measurements. Comparing HTRI data trends to the bundle flow rate measurements from the literature, we developed an improved circulation model for kettle reboilers. The improved model predicts a higher recirculation, especially at a high vapor generation, which also improves the thermal...
