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…
Decreasing the dependence on expensive platinum-group metals like iridium is vital for the expansion of “green” hydrogen production via proton-exchange membrane (PEM) water electrolysis. Efforts to develop lower-iridium catalytic components for electrolysis have typically focused on mixing iridium into a…
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…
Polybutadiene (PB) and acrylonitrile butadiene styrene (ABS) are widely used polymers in a number of products (including vehicle tires, kitchen appliances, computer hardware, toys and others), but are not generally recycled. Researchers at Oak Ridge National Laboratory (ORNL; Oak Ridge,…
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)…
Effective measurement of corrosion on process equipment and plant structures offers several benefits to plant operators. These include providing early warnings about damaging process conditions that could lead to corrosion-induced failures, establishing correlations between changes in process parameters and their…
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…
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…
KSE 3.0 safety valves (photo) replace their predecessor’s polytetrafluoroethylene (PTFE) housing lining with PFA copolymer, which is thermoplastic processable and transparent, facilitating visual quality inspection of the lining. For a seamless replacement, the leg dimensions of the new PFA-lined safety…
Establishing novel materials and systems is challenging for new companies. However, startup companies can streamline their research and drastically accelerate product development with effective tools and strategies While long-standing organizations are often challenged with digitizing large volumes of unstructured historical…
