This summer is proving to be a hot one across much of the U.S. as heat waves grip many regions with little relief from nighttime cooling. If it seems like it has been getting hotter, there are data to support…
The costs associated with installing and maintaining pressure-relief valves (PRVs) can often be reduced by equipping systems with upstream rupture discs Reclosing pressure-relief devices, commonly referred to as pressure relief valves (PRVs), are designed to allow for the release of…
Understanding material characteristics is important in designing and defining process criteria for optimal performance of rotary and fluidized-bed dryers The ability to efficiently, reliably and consistently dry bulk solids in an industrial setting relies largely on tailoring the dryer’s design…
The Solidmix technology (photo) is suitable for the pre-drying of shredded battery scrap and has been optimized for the separation of the solvents contained in the batteries. By means of vacuum drying, the solvents can be quickly and reliably separated…
Looking at the challenges and benefits of various recycling technologies, this article uses polymethyl methacrylate (PMMA) as an example to analyze the economics and design considerations for depolymerization processes Plastics are a valuable commodity in society and provide versatile materials…
The pneumatically actuated P40 PD tank-bottom valve (photo) is designed for use in sterile applications. The sealing principle of the valve is based on the company’s PD sealing technology, which hermetically separates the actuator from the medium. All actuator parts…
Three of the critical aspects of dust collection systems are properly identifying necessary dust capture points, effectively capturing dust at each point and accounting for solids loading in the ductwork. Key considerations for these aspects are presented here Dust collection…
The inclusion of nozzle flexibility (directional spring rate) in pipe-stress analysis results in more realistic piping reactions on pressure-vessel nozzles, whereby it will be easier to meet the limited nozzle-load capacity of the nozzles. It will surely contribute to a…
The Viper-28 flange-spreading wedge (photo) is said to be the most powerful flange spreader in the world, boasting a spreading force of 28 metric tons and a precision tip measuring just 5 mm. This tool handles a wide range of…
Ethernet-APL fulfills the promise to bring digitalization to every corner of a process plant. The fast and efficient communication of large amounts of data is barrier-free and reliable in potentially explosive areas. At 10 Mbit/s, the transmission of enormous amounts…
