The MellapakEvo structured packing has been developed to enhance the efficiency and capacity of distillation columns, maximizing…
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 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…
Bio-based polymers, such as polyhydroxyalkanoate (PHA), are seeing increasing application as a more sustainable alternative to fossil-based materials. A new, flexible production platform developed by CJ Biomaterials, Inc. (Woburn, Mass.; www.cjbiomaterials.com) is now enabling the production of PHA in both…
Researchers from the Fraunhofer Institute for Ceramic Technologies and Systems (IKTS; www.ikts.fraunhofer.de) and the Fraunhofer Institute for Electron Beam and Plasma Technology (FEP; both Dresden, Germany; www.fep.fraunhofer.de) are introducing an eco-friendly, biologically induced method of producing biogenic construction materials as…

A new biomass-based liquid admixture for concrete uniquely combines the benefits of traditional performance-enhancing additives with decarbonization. Hydrous bio-graphene oxide (hBGO), developed by AlterBiota (Edwardsville, Nova Scotia, Canada; www.alterbiota.com), is a stable, high-solids dispersion that helps to improve strength and…
At Achema in June, GIG Karasek GmbH (Gloggnitz, Austria; www.gigkarasek.com) introduced the ECO2Cell, an electrochemical CO2-recycling technology that utilizes proprietary catalysts to convert captured carbon dioxide into a range of chemicals. Using only water, CO2 and electricity as process inputs,…
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…
