Absorption and stripping are important mass-transfer operations within the chemical process industries (CPI). This one-page reference provides some basic information on the principles and applications of stripping and absorption in industrial chemistry settings. General operation In absorption, a solute from…
These powders are designed for thermal spray applications This company’s WallCarb™ HVOF (high-velocity oxygen fuel) tungsten carbide powders are designed for thermal spray applications (photo) and are engineered to provide dense, hard coatings with exceptional wear and corrosion resistance. These…
A pilot plant intended to manufacture silica aerogel products for different applications, including spray insulation, is being planned by the company Aeroskin Tech AG (Zurich, Switzerland; www.aeroskintech.com). Aerogels are dried gels that maintain their volume when dried, and have nanoscale…
Whether cautious or cutting-edge, operational technology (OT) teams need a balanced approach to cybersecurity — one that starts with understanding their current state, collaborating with subject matter experts and building a practical roadmap to success There can be little doubt…
Olivine, a magnesium-iron silicate mineral, is common in the earth’s subsurface, and can sometimes contain other valuable elements, such as cobalt, manganese and nickel. Olivine has been explored as a possible sink for atmospheric carbon dioxide in carbon-capture methods that…
Algae show promise for removing nutrients like phosphorus and nitrogen from wastewater due to their natural absorption abilities. However, the widespread use of algae-based wastewater treatment is limited by challenges related to system footprint, mass transfer and maintaining optimal conditions…
