Scaleup for an ethanol-to-ethylene process
Last May, Axens (Rueil-Malmaison, France; www.axens.net) started up the first ethanol-to-ethylene pilot plant based on Axen’s Atol technology with Sumitomo Chemical Co., Ltd. (Tokyo, Japan; www.sumitomo-chem.co.jp). The pilot plant, located at Sumitomo Chemical’s Chiba Works, will produce ethylene from ethanol.…
Wireless Data Collection: Stop Chasing Reliability Data
A routes-by-exception reliability strategy helps improve safety and efficiency, while preserving competitive advantage in a changing marketplace In recent years, maintenance and reliability experts have often talked about the massive wave of retirements leaving chemical plants, creating a shortage of…
A more stable way to upcycle waste plastics
A new advanced recycling process simplifies the task of breaking down polymer chains and stabilizing the resulting fragments. The Hydrochemolytic technology (HCT), developed by Aduro Clean Technologies, Inc. (Sarnia, Ont., Canada; www.adurocleantech.com), involves processing waste plastic with water, an inexpensive…
Designing a Multi-Stage Thermal Oxidizer System
Thermal oxidizers can be used for the abatement of a wide range of air pollutants and volatile organic compounds. This article describes the custom design of a thermal oxidizer to treat three different waste streams from a biogas plant A…
Hydrothermal synthesis of cobalt-free lithium-ion-battery cathodes
Researchers at the U.S. Department of Energy’s (DOE; Washington, D.C.; www.energy.gov) Oak Ridge National Laboratory (ORNL; Oak Ridge, Tenn.; www.ornl.gov) have developed a hydrothermal-synthesis method for high-voltage lithium-ion battery cathodes that avoids several key issues with traditional battery processing. Key…
Harvesting hydrogen from humid air
Chemical engineers from the Swiss Federal Institute of Technology Lausanne (EPFL; www.epfl.ch), in collaboration with scientists from Toyota Motor Europe (Zaventem, Belgium; www.toyota-europe.com), have invented a photoelectrochemical (PEC) “artificial leaf” that splits water vapor into H2. The technology features a…
Quantum-based tool searches quadrillions of materials to optimize catalysts
For the first time, a quantum-computing-inspired tool has been used for catalyst discovery — specifically for the investigation of a new catalyst for the production of hydrogen via electrolysis. Created jointly by scientists from Fujitsu Ltd. (Tokyo; www.fujitsu.com) and the…
Carbon sequestration in synthetic construction aggregate
Blue Planet Systems (Los Gatos, Calif.; www.blueplanetsystems.com) and Sulzer Chemtech Ltd. (Winterthur, Switzerland; www.sulzer.com) have announced a partnership to accelerate development of Blue Planet’s process for mineralizing carbon dioxide gas into construction aggregate for concrete. By sequestering CO2 into the…
Capture ammonia reversibly with this new MOF
Production of ammonia by the Haber-Bosch process not only requires a lot of energy for the high-temperature (300–500°C) synthesis of NH3 itself, but the recovery of ammonia takes place by condensation at –20°C. As a result, large changes in both…
A colorful new way to visualize gaseous properties
Japan’s National Institute for Materials Science (NIMS; Ibaraki, Japan; www.nims.go.jp), along with Harvard University (Cambridge, Mass.; www.harvard.edu) and the University of Connecticut (Storrs, Conn.; www.uconn.edu), have designed a new imaging device that uses structural colors — visible colors that change…
