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…
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…
Tanning Agent Södra Skogsägarna (Södra; Växjö, Sweden; www.sodra.com) is investing in a production line at Värö that will create a tanning agent from tree bark. This new tannin can be used to process leather in a more environmentally friendly way,…
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…
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…
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…
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…
Process heating systems are critical parts of chemical process industries (CPI) facilities. Unfortunately, the reliable, efficient operation of utility systems is often taken for granted, and they receive little engineering attention. This is perhaps understandable, since these systems play a…
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…
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…
