In November 2023, the first commercial test was initiated for a novel, fouling-immune membrane for brackish-water reverse osmosis (BWRO) applications through an early-access program. Membrane developer ZwitterCo (Woburn, Mass.; www.zwitterco.com) says its membrane is fouling-immune in cases where fouling of…
Direct-air capture (DAC) of atmospheric carbon dioxide presents promise for helping to reach global-warming reduction goals. However, many DAC technologies are hindered by high costs and inefficiency. RepAir Carbon (Yokne-am Illit, Israel; www.repair-carbon.com) recently launched a field prototype of its…
Energy recovery in spray-drying processes can reduce production costs, but involves trade-offs. Using milk powder as an example, this article describes a spreadsheet method to evaluate exhaust-gas recirculation scenarios for optimizing spray drying Dairy processing is among the most energy…
Capturing natural gas from petroleum drilling wells is economically challenging, but would have positive environmental impacts because it would eliminate the need for flaring and could allow the hydrocarbons to be converted into useful chemicals. Now, research led by chemists…
To decarbonize steel production and its high carbon dioxide emissions, Fraunhofer researchers, TS Elino GmbH (Dürren; www.elino.de) and Salzgitter AG (all Germany; www.salzgitter-ag.com) are working on converting an existing steel mill to climate-neutral production methods. The aim is to produce…
Using concentrated solar thermal (CST) energy to supply industrial-heating requirements is a promising way to reduce the use of fossil fuels. This is the aim of Magaldi Green Energy (Rome, Italy; www.magaldigreenenergy.com), which developed its Solar Thermo Electric Magaldi (STEM)…
OmniGrade (photo) is a residual-gas analysis (RGA) system that is designed to meet specific testing demands. OmniGrade configurations include two or three chambers: the spectrometer chamber in which the mass spectrometer is positioned, and a measurement chamber where the samples…
Remove PFAS from water with this ion-exchange resin MonoPlus TP 109 (photo) is a new macroporous anion-exchange resin for the selective removal of contaminants, such as per- and polyfluoroalkyl substances (PFAS) from water. Lewatit MonoPlus TP 109 is especially suitable…
In November 2023, Heirloom Carbon Technologies (Tracy, Calif.; www.heirloomcarbon.com) unveiled the United States’ first commercial direct air capture (DAC) facility, which can capture up to 1,000 ton/yr of CO2. The process first uses renewable energy to remove CO2 from limestone…
The new ASCO Series 327C solenoid valve (photo) features a direct-acting, high-flow design that provides superior flow-to-power ratio compared to similar valves. The Series 327C design features a balanced poppet construction that permits high flows at minimum power levels, making…
