Abstract
Improvements in tubes, which increase the heat exchange capacity of tubular heat exchangers using the tubes, are described. These improvements involve the use of one or more external surface enhancements, optionally combined with an internal enhancement and/or differing tube geometries. These improvements apply, for example, to internal condensers, including those in which the tube bundles are oriented vertically, in vapor-liquid contacting apparatuses such as distillation columns.
