Commissioning completed for a carbon-capture pilot plant that uses a novel solvent

Commissioning is wrapping up this month for a pilot facility designed to validate the capabilities of a new carbon-capture solvent. The pilot plant was constructed by Koch Modular Process Systems (KMPS; Paramus, N.J.; www.kochmodular.com) as part of Project Enterprise, a…

Direct-air capture of CO2 via a liquid-based, low-temperature, thermochemical system

With global temperatures likely to rise beyond the 1.5°C target set by climate experts, negative emissions technologies — most notably direct air capture (DAC) — become increasingly important for addressing CO2 already in the atmosphere. A new DAC approach is…

New adsorbent removes radioactive cesium ions from nuclear wastewater

One of the major byproducts of the nuclear fission process used for power generation is 137Cs, a radioactive isotope of Cs that has a half-life of 30 years and is often removed from nuclear-power-plant wastewater via selective adsorption using ion…

Autonomous control of a distillation column

Eneos Materials Corp. (formerly the elastomers business unit of JSR Corp.; www.eneos.co.jp) and Yokogawa Electric Corp. (both Tokyo, Japan; www.yokogawa.com) recently reached an agreement to officially adopt Yokogawa’s autonomous-control artificial intelligence (AI) technology for use at an Eneos Materials chemical…

Lithium metal for next-generation batteries produced from Li2CO3 in pilot facility

In May, Li-Metal Corp. (Markham, Ont.; www.li-metal.com) announced the production of refined lithium metal from lithium carbonate salt using a new electrolysis process at the company’s pilot facility in Ontario, Canada. The lithium metal produced at the pilot plant is…

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 —…

Recovering proteins — and more — from rapeseed

Last month, a pilot plant officially opened at the Fraunhofer Center for Chemical-Biotechnological Processes (CBP; Leuna, Germany; www.cbp.fraunhofer.de). The plant aims to further develop a process that recovers multiple products from rapeseed, including high-grade, pre-raffinate-quality rapeseed oil, a high-grade, protein-rich…

Spinning reactor recovers metals from spent Li-ion batteries

Recycling lithium batteries (LIBs) requires extensive use of hydrometallurgy, which requires multiple steps of extraction-stripping processes, each requiring separate reactors and different parameters. Although there have been attempts to devise a single-step, one-pot solution by partitioning the reactor using membranes,…

Pilot trials for a carbon-capture process that combines VPSA and MOFs

This summer, pilot trials will begin at a Buzzi Unicem S.p.A. (Casale Monferrato, Italy; www.buzziunicem.com) cement plant in Monselice, Italy, which will perform field tests of a new carbon-capture process developed by Nuada, the new tradename of MOF Technologies Ltd.…

Ligand-based separation method for rare earth elements

Rare-earth elements (REEs) are difficult to separate because of their similar properties, so conventional methods are often costly and generate significant amounts of waste. Researchers at Oak Ridge National Laboratory (ORNL; Oak Ridge, Tenn.; www.ornl.gov) have developed a new technique…
