It is essential that heat transfer systems for chemical processes are designed to maximize efficiency. Because the heat transfer step in many chemical processes is energy intensive, a failure to focus on efficiency can drive up costs unnecessarily.
The transfer of heat from one fluid to another is an essential component of all chemical processes. Whether it is to cool down a chemical after it has been formed during an exothermic reaction, or to heat components before starting a reaction to make a final product, the thermal processing operation is core to the chemical process.
Thirty years ago, heat transfer fluid (HTF) manufacturers would sell virgin fluids at inflated prices and dispose of the used thermal fluids without regard for the potential of remediating the used fluid. Times have changed.
One of the most common pieces of equipment in many industries is a heat exchanger. As its name implies, it is designed to move heat from a process fluid to another fluid — which might be liquid or air. The process fluid is heated or cooled as the application demands. The transfer fluid might be air or a liquid, also as the application demands.
When heat must be dissipated from a process fluid — either liquid or gas — it is usually transferred to another fluid — either liquid or gas — using a heat exchanger. The two most common types of heat exchangers are liquid-to-liquid and liquid-to-air.

In Process Heating's annual Equipment Overview on Heat Transfer Fluids, we have compiled all the data you need to choose a fluid that can take the heat - and move it to wherever you need it to go.
Education is crucial when it comes to selecting the right valve for your hot oil application. You don’t want to waste valuable resources by installing a gland-packed valve when a bellows-sealed valve is really what’s needed. Click here to read about a processing plant that had made safety provisions for its leaking valve a part of its SOP—because no one there knew better.
A collection of tips and practical guidelines from industry experts on thermal fluids and related operations...summarized advice intended to take the guesswork out of dealing with heat transfer fluids and to improve the overall user experience.
