Choosing the right heat transfer fluid is the first step to enhancing the efficiency of your applications and the performance of your equipment. The second is understanding how to keep that fluid performing at its maximum capacity – so you…
For every application, there’s an evaporator or dryer that can boost performance In today’s economy, chemical processors must deliver high product quality and uniformity while maintaining high yield and low production costs in order to be successful. For this reason,…
When it comes to protecting the performance of your applications—from the extremes of solar energy production to pharmaceuticals and throughout the multitude of processes in between—choosing the right heat transfer fluid is crucial, but it’s not the only step. Ensuring…
Hot-oil heat-tracing systems use liquid heat-transfer fluids to reliably deliver heat to process fluids. Heat tracing may be used in place of jacketed equipment, often at lower cost and with lowered risk of cross-contact. The use of liquids reduces many…
Ensuring optimal performance of shell-and-tube heat exchangers requires knowledge of the controlling fluid, correct exchanger geometry and configuration, as well as proper fluid placement Satyendra Kumar Singh Simon India Ltd. Optimizing the thermal design of a shell-and-tube heat exchanger…
Applying dynamic simulation models to tube-rupture scenarios can help ensure more accurate sizing and hazard assessments Tube rupture in heat exchangers is an extremely serious issue in the chemical process industries (CPI; Figure 1). Heat-exchanger tube-rupture scenarios can be evaluated…
Researchers from the Fraunhofer Institute for Environmental, Safety and Energy Technology (Umsicht; Sulzbach-Rosenberg; www.umsicht.fraunhofer.de) and RWTH Aachen University (both Germany; www.rwth-aachen.de) have developed a new phase-change material (PCM) trade-named CryoSolPlus. The PCM is a dispersion of solid paraffin beads and…
Guidelines are presented to better understand the temperature profiles of high-velocity gases In high-velocity gas flows, such as those that may occur within the discharge piping of a pressure-relief or depressurization valve, the temperature experienced at the wall of the…
Bulk solids are frequently used as reactants, catalysts or products in chemical process industries (CPI) operations. Often, they must be heated or cooled so that they can be handled safely or processed at a desired temperature. Traditionally, heat transfer to…
Burners are mechanical devices that are utilized for mixing proper quantities of fuel and air, and also for maintaining a stable flame inside fired equipment. Burners are critical components that must be periodically maintained to ensure the reliability of fired…
