Polymer electrolyte membrane (PEM) electrolysis uses a membrane-electrode assembly (MEA) that integrates the electrolyte membrane and electrode (diagram). Large-scale hydrogen conversion of electricity requires a large number of MEAs, which is a drawback for scaleup, because the MEA relies on…
In June, the newly developed, dust-tight OEB version of the DDSR20 2.0 twin-screw feeder (photo) passed the highest occupational exposure bands (OEB) classification certification, OEB5. OEB classifications are used to grade substances accurately into “classes” or “ranges” based on the…
Hollow silica particles (HSPs) are materials of interest for thermal insulation applications because of their very low thermal conductivity, but the particles pose health hazards and the powder is impractical to use, so scientists have been trying to incorporate HSPs…
Due to favorable properties, such as light weight and corrosion resistance, plastic-piping systems are suitable for a growing number of applications Over the past few decades, plastic-piping systems have been adopted in many different sectors of the chemical process industries…
A highlight of this company at Valve World 2022 (November 29–December 1; Düsseldorf, Germany) is the new Digital Valve Kit (DVK), which provides plant operators with remote access and remote control of their valves, as well as indicating the current…
At Powtech last month, this company presented completely new, more wear-resistant screen cloths that, compared to previous standard cloths, achieve an increased service life with abrasive bulk materials. Matched to the wire thickness and mesh size, the screen cloths are…
A new protocol for safer chemical design is helping to overcome gaps in ‘traditional’ toxicology and improve upon federal regulations for endocrine-disrupting chemicals Research over the past two decades shows clearly that some chemicals manufactured for product functionality can have…
Last month, Metso Outotec Corp. (Helsinki, Finland; www.mogroup.com) introduced NextGen Pelletizing — a visionary concept for the next generation of iron-ore pelletizing plants that strive to be carbon neutral and autonomous. According to the company, the combination of innovations —…
The Vertical Cartridge Filter (VCF; photo) is a pulse-jet filter designed to handle medium to high air volumes for industrial dust removal. It is typically used as a nuisance dust collector in applications with light dust loads and a high…
With a minimal footprint of approximately 1 m², the compact Aircenter systems (photo) are available for flowrates from 0.34 to 2.7 m³/min and also provide application-specific compressed-air treatment and storage. All Aircenter models are characterized by their exceptional efficiency. At…
