A custom-engineered industrial heat recovery system utilizes thermal recycling, reusing process energy that would otherwise be wasted.

The process-efficiency benefits of utilizing heat from one part of an industrial process in another are well understood. Heat reuse — sometimes referred to as regeneration — is widespread across a range of processes: pasteurization and sterilization, evaporation, drying, distillation, pressurization, cooking, space and media heating, and reactor heating, to name a few. In fact, the list of applications is as varied as the industries themselves.

Here are the most popular Process Heating articles of 2018.

In this issue of Process Heating, we include articles about heat transfer fluids, heat recovery and pollution control technologies, among others.

Secondary heat recovery systems capture excess energy in the exhaust stream of processes or oxidizers. On the surface, heat recovery makes good sense: Capture the waste energy and repurpose it rather than throwing it out an exhaust stack. The concept sounds relatively straightforward. As with most things, however, the proof lies in the details.
