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...

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 using...

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...

HTRI investigated the accuracy of equilibrium multicomponent condensation models applied on the shell side of a bundle with 19.05-mm OD plain tubes. Tests were conducted in the Low Pressure Condensation Unit (LPCU) over a range of vacuum pressures (7 – 81 kPa) and fluid inlet flow rates [5 (10-3) – 7...
