Desalination heat exchangers

The calculations carried out to design heat exchangers are far from exact. In fact Perry’s refers to the design of heat exchangers as being an art as much as a science. These days almost all heat exchanger designs are carried out using software specifically written for the purpose. The most accepted software used for heat […]

The main consideration in the selection of condenser types and orientations is the type of fluid being condensed. For condensation of pure components use a horizontal exchanger and place the process on the outside of the tubes. If there are significant quantities of non-condensable present; condense inside the tubes with a vertical orientation and downward [...]

Place viscous fluids on the shell side. Pressure drops are easier to minimize on the shell side.

Shell and tube exchangers can be designed for almost any service. All other exchanger types are compared to shell and tube. Hairpin type exchangers are a good choice when one fluid is at a very high pressure. Hairpin exchangers are a good choice when there is a large difference in temperature between the two fluids. [...]
