Photochemistry boosts the yield of chiral compounds
Isolation and purification of pure, active enantiomers is important in the development of active pharmaceutical ingredients and drug products. However, recovering the desired optical isomer from a racemic mixture means half of the chemical produced — the undesired isomer —…
Innovations in Mixing Maximize Efficiency
Developments in mixing technologies permit efficient use of energy and resources and manage challenging applications Mixing equipment hadn’t changed much in the past 50 years until recently when chemical processors began demanding more efficiency from their mixing operations due to…
Keys to Designing Sustainable Production Facilities
Using the food-and-beverage industry as an example, these considerations can help engineers design new facilities with sustainability built in Rapid population growth and geopolitical tensions continue to keep food security a top priority for nations all over the world. These…
Real-Time Particle-Size Analysis Technologies: Overview and Case Study
Monitoring particle sizes in real time can improve product quality and reduce costs in chemical processes. Presented here is an overview of available technologies for particle-size analysis and an example involving suspension polymerization Effective measurement, in real time, of particle…
Use existing refinery infrastructure for hydrogen storage and transport
Hydrogen is a clear piece of the decarbonization puzzle for many industrial sectors, including petroleum refining, but a major challenge lies in the storage and long-distance transport of hydrogen in its gaseous form. One proposed solution is the use of…
Thyssenkrupp nucera partners with OxyChem to install next-generation chlor-alkali electrolyzers
Thyssenkrupp nucera AG & Co. KGaA (Dortmund, Germany) is partnering with OxyChem to install the latest generation eBiTAC v7 electrolyzers to support the conversion of its Battleground plant in LaPorte, Texas, from the diaphragm to membrane chlor-alkali technology. "The fact…
Introduction to Activated Carbon
Understanding the different types of activated carbon products, their specific properties and best practices for use is essential to the design of effective environmental treatment processes Activated carbon is a type of manufactured carbon material used for a range of…
These nonwovens are electrically conductive, but thermally insulating
Researchers at the University of Bayreuth (Germany; www.uni-bayreuth.de) have developed nonwoven materials that exhibit an unusual combination of high electrical conductivity and extremely low thermal conductivity. These composites of carbon and silicon-based ceramic can be manufactured and processed cost-effectively by…
Converting algae shells into ‘tunable’ perovskites
A research team, led by scientists at the Center for Molecular Bioengineering (B CUBE) at the Technical University of Dresden (Germany; www.tu-dresden.de), has converted mineral shells of single-celled algae into lead-halide perovskites with tunable physical properties. The new perovskites have…
Bio-inspired synthesis leads to new hydrogen-reaction mechanism
In synthesizing a new molecule that mimics the nickel-iron (NiFe) hydrogenase enzyme, a team of researchers from University of Illinois Urbana-Champaign (www.illinois.edu) may have uncovered a promising alternative to the platinum-based catalysts typically used in the electrolysis of water to…
