First commercial DAC facility in the U.S. captures CO2 for concrete
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…
Converting natural gas to alcohols using MOFs
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…
Converting a steel mill to climate-neutral steel production
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…
Residue-gas analyzers for cleanliness verification
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…
A continuous electrochemical process for direct-air CO2 removal
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…
A hub for the digitalization of data from safety devices
Whether in the engineering of large and distributed automation projects, in the diagnosis of faults or in regular testing, the specification, configuration and maintenance of safety devices in process plants requires effort and careful attention. If new functions are added…
These solenoid valves handle high flow with minimum power
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…
A workstation with an aluminum housing for harsh conditions
This company expanded its portfolio of VisuNet FLX series operator and monitoring workstations (photo) with a version for outdoor use and use in an extended temperature range from –20 to 50°C. The new aluminum housing not only ensures an optimal…
Digital service significantly reduces compressed-air costs
The Monitoring Box FTMg Premium (photo) is a new digital service for compressed-air monitoring. In addition to continuous monitoring, the Cloud solution from this company’s Field Analytics Portfolio can identify consumption losses due to machine- or process-related inefficiencies and detect…
Optimized dosing solution for drip applications
The newly developed vipro-Pump MR series (photo) offers plant operators a virtually maintenance-free dispenser that doses all conventional impregnating resins — even chemically aggressive ones. A patent application has been filed for the vipro-Pump MR and the associated process. The…
