Aluminum smelting operations require molten cryolite, also commonly called bath, to serve as the electrolyte and dissolve alumina. A typical smelter produces excess bath over time, and there are few markets for reuse or recycle of this material, especially as…
A team of scientists at Pacific Northwest National Laboratory (PNNL; Richland, Wash.; www.pnnl.gov) recently unveiled a modified version of the “superalloy” Inconel 617, in which cobalt — a component of the alloy that is also a critical material with significant…
The new CablePro tubular drag conveyor (photo) is designed with components that offer chemical compatibility, including corrosion-resistant coatings and polished stainless-steel tubing. It is equipped with self-lubricating disks, which are injection-molded directly onto a pre-stretched, oil-lubricated stainless-steel braided cable with…
For product developers, understanding a substance’s biodegradability is essential in many applications to ensure compliance with toxicity and environmental regulations. Aropha, Inc. (Cleveland, Ohio; www.aropha.com) has developed a platform for biodegradability testing that reaches far beyond the typical breadth of…
Enhanced measurement capabilities offer more reliable control to boost quality, reduce waste and ensure safety As optimization, sustainability and safety initiatives continue to be a driving force in the chemical process industries (CPI), accurate, responsive and reliable temperature measurements are…
A new approach to enzyme engineering has overcome many of the operating challenges associated with large-scale bio-based manufacturing processes by designing enzymes that can thrive outside living cells, eliminating complexity and improving reaction yields. eXoZymes’ (Monrovia, Calif.; www.exozymes.com) cell-free enzyme…
One way to develop safer, more-sustainable chemical processes is to substitute potentially harmful chemicals with less-risky alternatives. Organic solvents, which are widely used in industrial processes, can pose health, safety and environmental risks. Researchers at Rice University (Houston, Tex.; www.rice.edu)…
The industrial production of aluminum involves electrolysis of alumina (Al2O3) in molten cryolite, a mineral used as a solvent for the aluminum oxide raw material. Over time, the cryolite accumulates impurities, such as sodium, lithium and potassium ions, which degrade…
Coveralls for chemical and fire protection This company’s recently launched Tychem® 6000 SFR is a lightweight, hooded garment (photo) designed to help protect people working in challenging environments against multiple chemical and flash-fire hazards. Tychem garments may be suitable for…
By leveraging advanced analytics platforms, chemical processors are revealing pump trends and insights that help increase operational efficiency In the information age, centralized monitoring technologies offer countless benefits for the chemical process industries (CPI). Using data generated by sensors installed…
