Kettle Horizontal Reboilers, Alternative Designs

Referring to the procedure of Palen and Small [90] and Palen and Taborek [91], this is an alternative check on the previously suggested procedure. This technique should generally be restricted to single fluids or mixtures with narrow boiling ranges (a wide boiling range gives too optimistic results). The mean temperature difference between the bulk boiling liquid temperature and tube wall should be greater than 8°F; the ratio of pitch to tube diameter should be 1.25 to 2.0; tube bundle diameters should be greater than 1.0 ft and less than 4 ft; and boiling must be less than 400 psia. Vacuum operations may give optimistic results and are not to be used on polar compounds.
