Commercial debut for a batch reverse-osmosis system
Earlier this year, Salinity Solutions Ltd. (Coventry, U.K.; www.salinitysolutions.co.uk) signed an agreement with Te-Tech Process Solutions (Totton, Southampton, U.K.; www.te-tech.co.uk) to manufacture commercial water-purification systems based on batch reverse-osmosis (RO). This technology, originally characterized and developed at the University of…
World’s largest double, re-slurry crystallization unit starts up in China
Last month, the world’s largest double re-slurry para-xylene crystallization unit was started as part of Shenghong Refining and Chemicals Co. Ltd.’s integrated refining/chemicals project in Lianyungang, Jiangsu Province, China. Double re-slurry crystallization takes advantage of freezing-point differences among the three…
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…
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…
Onsite bioelectrochemical treatment for ultra-concentrated wastewater
The combination of electrochemical principles and microbial activity is the backbone of a treatment technology designed specifically for ultra-concentrated and challenging industrial wastewater. The Bioelectrochemical Treatment Technology (BETT) developed by Aquacycl (Escondido, Calif.; www.aquacycl.com) involves “microbial fuel-cells” that produce direct…
Chementator Briefs
Using Waste Heat To convert large amounts of waste heat into electricity as efficiently as possible, turbines with a high degree of efficiency are required that work with a special conversion process — the organic Rankine cycle (ORC). In a…
A hydrogen-fired furnace for ceramics
This month, a demonstration experiment will begin on a new firing furnace for ceramics that is being developed by NGK Insulators, Ltd. (NGK; www.ngk.co.jp). The furnace is fired with hydrogen instead of fossil fuels, thereby reducing CO2 emissions. H2-fired combustion…
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…
