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.
Imagine a machinist running a screw machine, turning out hundreds of parts with a male thread. To verify the thread size is in tolerance, he or she checks samples using two gauges with corresponding female threads.
Thermal fluids have proven exceptionally safe in a wide range of industries. However, it is difficult to completely prevent fires in these systems because the necessary ingredients for a fire—fuel, air and ignition source—are present by design.
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.
