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.
Anyone who has spent even passing time in the Midwest will have noticed a key difference among the seasons. There’s fall (nothing to do), winter (nothing to do), spring (still nothing to do) and festival season — I mean summer.
Electrical equipment is almost always specified by manufacturers for operation within an optimal temperature range. That range is defined by the conditions that will ensure the equipment’s reliability, performance, efficiency and physical integrity are protected.
Boilers and heat exchangers are integral parts of many industrial plants. Often, when people think of protecting these components from corrosion, their minds fast-forward to corrosion issues that occur after the equipment is installed.
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.
The probable cause of an explosion and fire was a failure of the brazed aluminum heat exchanger (BAHX) due to thermal fatigue, says the U.S. Chemical Safety Board. The CSB has released its final report of the June 27, 2016, investigation of the explosion and fire at the Enterprise Products Pascagoula Gas Plant in Pascagoula, Miss.
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.
The RHD Series has a continuous scraping action to enhance the mixing of viscous products. Its sealing system allows for the removal of individual tubes for cleaning or maintenance while offering increased strength.
Inline heat exchanger makes use of different types of mixing in the heat transfer system to help users meet their unique mixing requirements. Komax Klean employs high-pass mixing elements that are designed to create turbulence at the pipe walls and reduce boundary layers.
