Models are proposed for the design and analysis of kettle reboilers, often found in refineries, as well as horizontal units, which have received scant attention in the literature. For reboilers of the shell-and-tube type, there are 3 principal geometries: vertical thermosiphon, in-tube boiling; kettle (horizontal), shell-side boiling; and horizontal thermosiphon, shell-side boiling. Performance data on horizontal thermosiphon reboilers are needed to validate whatever model is selected for analysis or design. The described model appears logical and undoubtedly represents the mechanisms that actually occur. It is based on an analogy to the model for vertical thermosiphons with in-tube boiling, and that model has been demonstrated as reliable. In the absence of validation data, the present model is still useful for evaluating effects of process variables.
