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…
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…
The Sakura and Sakura Mini next-generation premium pilot reactors (photo) incorporate the latest reactor-vessel technology to provide enhanced performance and efficiency for chemical process scaleup. Sakura includes vessels of up to 100 L, with the option to upgrade to this…
Plant Watch Trelleborg Group to construct new production plant in North Carolina July 16, 2024 — Trelleborg Group AB (Trelleborg, Sweden; www.trelleborg.com) is investing in a new production facility to expand its business for engineered coated fabrics in Rutherfordton, N.C.…
At a press conference during Achema 2024, Festo SE & Co. KG (Esslingen, Germany; www.festo.com) presented the BionicHydrogenBattery — a new concept for the simple storage and safe transportation of hydrogen. Currently, H2 can only be stored and transported safely…
Nitrile compounds (R–N≡N) are important for the manufacturing of fragrances, pharmaceuticals, superglue and chemical-resistant gloves. Currently, such nitrile compounds require the use of highly toxic cyanide in their synthesis. Now, an alternative cyanide-free chemo-enzymatic cascade process is being developed by…
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 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…
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 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…
