Recycling bauxite residues and electrowinning iron

Electrochem Technologies & Materials Inc. (Montreal, Canada; www.electrochem-technologies.com) produced pure electrolytic iron (99.995% Fe) using its patented FerWIN process (diagram) — a sustainable zero-carbon iron-making technology — from ferrous sulfate heptahydrate (copperas) originating from the sulfation of bauxite residues. This…

Global cement industry supports startups in drive to achieve ‘net zero’ by 2050

Last month, the Global Cement and Concrete Association (GCCA; London, U.K.; https://gccassociation.org) revealed the first six startups that will be backed by its member companies as part of the first ever Innovandi “Open Challenge” in the race to achieve “net…

Scaleup project for simultaneous carbon capture and conversion

A multidisciplinary project to scale up a system capable of simultaneously capturing carbon dioxide from fluegas and converting it to ethanol has received $1.9 million from the U.S. Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E; Washington, D.C.; arpa-e.energy.gov). The…

Heavy-duty mixers for very viscous materials

Heavy-duty FGM-series mixers (photo) feature a high-torque gear reducer to vigorously agitate heavy viscous materials. With a ring-mount design and two opposing handles, this powerful mixer mounts directly to 5-gal pails up to 12.25-in. wide. A quick-change coupler and shaft…

A robotic unit to expedite industrial cleaning

This company’s Ergo System (photo) is a compact hydrodemolition robot used for hazardous cleaning applications, such as those requiring the removal of concrete, coatings, paint, rust, plastic or other materials. The Ergo offers four times the power of a hand…

New catalyst geometry poised to re-shape ethanol-to-ethylene conversion

As chemical manufacturers continue to seek renewable alternatives for fossil-fuel feedstocks, bio-based ethanol is poised to be a crucial raw material in the ethylene value chain for products from jet fuel to plastics. The range of novel-shaped alumina catalyst developed…

Facts at your Fingertips: Clean-in-Place (CIP) Systems

Cleaning equipment surfaces is critical for processes involving biological materials to prevent microbial contamination. Clean-in-place (CIP) systems play a key role. In addition to preventing contamination, CIP systems also remove grit, scale and organic matter, which may affect process performance.…

New midsize models and features added in this PSA range

The NGP+ series of pressure-swing-adsorption (PSA) nitrogen generators (photo) is expanding with the introduction of two new models — the NGP 160+ and NGP 200+. The generators offer gas purity from 95% to 99.9995%, with flowrates up to 4,802 std.…

Use these diffusers to prevent settling in sewage-storage tanks

ProFlex 730CBD coarse-bubble diffusers (photo) are used to aerate or mix wastewater for effluent and sewage treatment, ensuring proper agitation of media with high specific gravity. This means that when the sewage is put into a storage tank, settling at…

A new generation of centrifugal mixers for 3D printing materials

Smart DAC centrifugal mixers (photo) feature variable counter-rotation, increased mixing weight (250 g up to 2 kg) and volume (310 mL up to 2.8 L) and allows up to 30 min of mixing time. The mixers feature real-time temperature control,…
