Concrete production is responsible for 6–9% of global anthropogenic CO2 emissions. “The largest contribution to that comes from the production of cement, a precursor product,” says Peter Stemmermann from the Institute for Technical Chemistry (ITC) at the Karlsruhe Institute of…
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…
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…
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 NEMO MY magnetically coupled pump (photo) is the latest upgrade of the NEMO progressing-cavity pumps. It was developed for more efficient and safer handling of media with high viscosities (up to 20,000 cP), such as slurries. However, using the…
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…
For the first time, perfusion disc separators for continuous production and faster processing can be implemented in biopharmaceutical cell-harvesting processes based on labor-saving, easy-to-use single-use devices. The newly introduced perfusion separators in this series (photo) offer the same advantages as…
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…
This company has launched an enhanced version of its Ninva TSP341-N non-invasive temperature sensor (photo), which is said to be the first SIL2-certified non-invasive temperature transmitter. Using the surface temperature of the piping to infer the process temperature, Ninva provides…
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…
