This month, SusPhos B.V. (Amsterdam, the Netherlands; www.susphos.com) is increasing the capacity ten-fold of its 25-kg/d pilot plant in Leeuwarden, the Netherlands. The pilot plant, which began operating in January, is being used to develop a process that recovers phosphorus…
Perfluorinated ion-exchange membranes are developing beyond legacy applications to find use in a wide variety of emerging markets, including renewable energy Ion-exchange membranes are used in numerous industrial processes, including seawater desalination, electrodialysis and the production of commodity chemicals via…
The ability to precisely control the molecular structure of polymer membranes could expand their use in challenging separations, such as the purification of xylene isomers. Using highly selective membranes that can be operated at ambient conditions to separate such hydrocarbons…
Last month, Climeworks (Zurich, Switzerland; www.climeworks.com) started operations of Orca, said to be the world’s first and largest climate-positive direct air capture (DAC) and storage plant. Located in Hellisheiði, Iceland, the Orca plant has a capturing capacity of 4,000 ton/yr…
A feasibility study is underway for the world’s first commercial facility that integrates direct air capture (DAC) of atmospheric carbon dioxide with gas fermentation of CO2 and production of aviation fuels. LanzaTech (Chicago, Ill.; www.lanzatech.com) and Carbon Engineering (Squamish, B.C.;…
A first-of-its-kind pilot project in Abu Dhabi is integrating large-scale atmospheric water generation (AWG) with solar-thermal energy storage to enable carbon-free production of water. Led by partners AQUOVUM LLC (Dover, Del.; www.aqvglobal.com), Masdar Clean Energy (www.masdar.ae) and Khalifa University of…
EnviroGold Global Ltd. (Toronto, Ont., Canada; www.envirogoldglobal.com) has filed a patent application for a proprietary electrochemical process designed to achieve advanced metal recoveries from refractory ores with reduced capital expenditures (capex) compared to industry standard solutions. “The residual metals contained…
A hydrometallurgical process for recovering vanadium from slag, a byproduct of steelmaking, has been significantly scaled up. Previously deployed at mini-pilot and bench scales, the process, developed by Neometals Ltd. (West Perth, Australia; www.neometals.com.au), has now been expanded by a…
Using a vast collection of experimental distillation-column data, sieve tray stability, and its influence on efficiency, are explored in terms of several physical and mechanical properties For trayed distillation columns, the concept of tray stability was introduced by the author…
Buildup of biofouling on membranal surfaces necessitates treatments with corrosive chemicals, such as hydrochloric acid, and even replacement of membrane cartridges, which can be costly in desalination operations. A new coating, developed in the laboratory of Ran Suckevereine at Kinneret…
