The first gold using a process without cyanide and without mercury has been produced using technology from CSIRO Minerals Technology (www.csiro.au) at a demonstration plant in the Western Australian goldfields town of Menzies. Cyanide is used in more than 90%…
Advances in sensing and imaging technologies have enabled new levels of accuracy in the measurement of bulk-solid materials stored in piles, silos and bins. BinMaster (Lincoln, Neb.; www.binmaster.com) and Stockpile Reports (Redmond, Wash.; www.stockpilereports.com) have collaborated to introduce the industry’s…
A Japanese consortium has started the construction of the Fukushima Hydrogen Energy Research Field (FH2R), which is said to be the world’s largest hydrogen-based energy system — a step towards a hydrogen-based economy. Located in Namie-cho, Fukushima Prefecture, FH2R will…
Thermal hydrolysis of wastewater sludge before it enters anaerobic digestion units can increase the rate of residuals-to-biogas conversion (biogas production) and increase the feed concentration, the combination of which significantly reduces anaerobic-digester reactor volume. An advanced thermal hydrolysis process (THP)…
Plant Watch Dow announces investment plans to increase global silicones production September 12, 2018 — The Dow Chemical Company (Dow; Midland, Mich.; www.dow-dupont.com) will make investments in its global silicones businesses, including plans to build a new hydroxyl functional siloxane…
New C-Series air-operated double-diaphragm (AODD) pumps (photo) are designed to enable the housing parts to be tightened to each other via housing bolts. Rather than using single bolts that press against the housing, all of the C-Series’ bolts are tightened…
Presented here are practical considerations concerning the equipment and methods used for experimental verifications of simulations The use of process simulation tools for modeling distillation columns is invaluable for designing plant-scale columns. However, it can be difficult to know if…
SerialTap (photo) is a new cybersecurity solution for legacy industrial control networks that rely on serial communication protocols, such as RS-485 and RS-232. SerialTap consists of a patented sensing device that passively intercepts serial communications on legacy industrial control networks…
This company’s Finish Thompson drum pumps and barrel-emptying pumps are now available with the TEFC (totally enclosed fan-cooled) IP55 motor (photo). The new motors include a powerful 1,000-W continuous-duty universal motor providing variable-speed operation from 0 to 12,000 rpm. The…
These versatile, modular valves enable quick installation More than 2,500 configurations are available in the the Spira-trol Control Valve family (photo). These modular valves are pre-commissioned in the manufacturer’s U.S. factory, and are shipped within two to three days of…
