Advanced technologies help pharmaceutical and semiconductor producers achieve excellence Chemical processors are under increased pressure to achieve operational excellence, which involves a balance of increasing yield, improving quality and reducing waste, while also cutting operational costs. Processors in high-purity industries…
Many separation processes depend on chemical or thermal principles, such as solvent extraction or distillation, but in some cases, mechanical methods can provide effective separations with lower cost and energy requirements. Eirex (Vaughan, Ont., Canada; www.eirex.ca) has developed a proprietary…
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…
Despite the abundance of nitrogen and hydrogen, industrial ammonia synthesis remains an energy-intensive process. Electrochemical methods have been suggested as potentially lower-energy alternatives to traditional ammonia synthesis, but these newer technologies often struggle with achieving key performance metrics. By integrating…
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…
A new thermolysis technology developed by Composite Recycling (Ecublens, Switzerland; www.composite-recycling.ch) breaks down fiber-reinforced polymers (FRPs) into their fundamental constituents, enabling reuse as valuable feedstock for the creation of new composite materials. “Past efforts to recycle composites have allowed waste…
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…
As the “Industry 4.0” revolution progresses, the convergence of IT systems with OT systems presents significant security risks. Presented here are strategies to bridge the divide between the two areas and secure plant operations The convergence of information technology (IT)…
