Divided flow and split flow arrangements are also used where the pressure drop rather than the heat transfer rate is the controlling factor in the design, to reduce the shell-side pressure drop. Steam may also be used to evaporate (or vaporise) a liquid, in a type of shell and tube heat exchanger known as a reboiler.
