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)…
Increased reliability, chemical compatibility and containment of sealing solutions are priorities for chemical processors Seals and gaskets may seem like an afterthought in the grand scheme of chemical processing equipment, but if you’ve ever been faced with unexpected — and…
As environmental and transportation regulations become more stringent around the world, treating spent acids is becoming less of an option and more of a necessity Acids play many different roles in a large number of sectors of the chemical process…
Around 70% of all chemical products use chlorine in their manufacturing process. At the same time, the production of this important base chemical is one of the most energy-intensive processes in the chemical industry. In order to change that, thyssenkrupp…
Petroleum refineries must meet increasingly stringent levels for sulfur content in fuel, but the conventional hydrodesulfurization approach requires high-pressures and temperatures. Alternative Petroleum Technologies Corp. (APT; Reno, Nev.; www.altpetrol.com) has piloted an oxidative desulfurization technology, known as Sulfex, that can…
