An electrochemical process for recovering sulfuric acid and metallic iron from iron-rich sulfate wastes, such as spent pickling liquors and pregnant leach solutions generated in minerals and metals processing, has been patented by François Cardarelli, an independent researcher located in…
Ultimo Measurement (Providence, R.I.; www.ultimompd.com) has developed technology for measuring density and viscosity of process fluids, loose solids and mixtures non-invasively — a percussion-based device that can be mounted on the outside of process tanks, pipes or other vessels. The…
A low-cost method for fabricating microfluidic diagnostics devices using cotton, paper, or other multifilament threads has been developed by a team from Monash University (Melbourne, Australia; www.eng.monash.edu.au). The devices can be used to provide qualitative and, at least, semi-quantitative analyses…
A new Cl2 process Oxygen-depolarized cathodes (ODCs) will be used for the first time to produce chlorine on an industrial scale in a 20,000 metric ton per year (m.t./yr) electrolyzer at the Krefeld-Uerdingen chemical park in Germany. The plant…
In late March, the world’s first demonstration plant for converting sugars directly into gasoline started up at the Madison, Wisc., facilities of Virent Energy Systems, Inc. (www.virent.com). The demonstration plant — part of a joint R&D collaboration of Virent and…
Honeywells UOP LLC (Des Plaines, Ill.; www.uop.com) has developed a process that makes a renewable, “drop-in” jet fuel from sustainable oils, including camelina, tallow, jatropha or algae. Similar to the the UOP/Eni Ecofining process for making Green Diesel fuel (CE,…
