Most chemical engineers involved with heat exchanger design are familiar with the concepts of nucleate versus film boiling and critical heat flux. Although a sensible heating medium, such as hot oil, may be used for some applications, most facilities employ steam at different pressure levels. This article explains how to account for the critical heat flux to avoid film boiling, and discusses the impacts of various heating media on the reboiler design.
