Almost all phosphoric acid is produced via the wet-acid process (WAP), which requires relatively pure raw materials and produces large volumes of a potentially hazardous, special waste called phosphogypsum, which is highly regulated in terms of storage and disposal. A…
In a first-of-its-kind endeavor, a hydrogen-fluoride-based alkylation unit producing linear alkyl benzene (LAB) is being converted into a solid-bed alkylation unit that employs UOP’s (Des Plaines, Ill.; www.uop.com) Detal-Plus alkylation technology for LAB. LAB is used in the production of…
Concern with energy efficiency has increased the popularity of window glass coatings that control the amount of sunlight that passes through, as well as windows made of thin solar cells that can turn them into electricity generators. Now researchers from…
Battery metals producer Australian Mines (Perth, Western Australia; www.australianmines.com.au) is scheduled to export the largest sample of battery-grade cobalt and nickel sulfate ever recorded from Australian mined and processed ore. The company will send 40 kg of nickel sulfate and…
At Achema 2018 (June 11–15; Frankfurt am Main, Germany), EvCon GmbH (Pliening-Landsham, Germany; www.evcon-water.com) showcased its new UPWater treatment system, which employs a patented vacuum multi-effect membrane distillation (VMEMD) technology to obtain ultra-pure water using less energy than comparable water-treatment…
The two main barriers to widespread use of fuel cells have been securing a reliable source of hydrogen that avoids CO2 emissions, and cost — they have traditionally depended on expensive platinum and palladium catalyst materials. GenCell Energy Ltd. (Petach…
Last month, thyssenkrupp Industrial Solutions AG (Dortmund, Germany; www.thyssenkrupp-industrial-solutions.com) launched industrial-scale water electrolysis systems that make large-scale hydrogen production from renewable electricity economically attractive. The advanced water electrolyzer (diagram) features a well-proven cell design paired with an especially large (2.7…
Last month, Nano Sun, a water technology start-up founded by a scientist from Nanyang Technological University (NTU; Singapore; www.ntu.edu.sg) launched a 3-D-printing facility to manufacture a new type of water-treatment membrane. Unlike conventional membrane-manufacturing processes, which use acids to make…
TPA from PET bottles A chemical method previously developed for recovering monomers from polyester blend fabrics and textiles has now been adapted for use with waste plastic bottles made from polyethylene terephthalate (PET). The BCD Group (Cincinnati, Ohio; www.bcdinternational.com) developed…
Sunvapor Inc. (Livermore, Calif.; www.sunvapor.net) was awarded a grant from the U.S. Dept. of Energy (DOE; Washington, D.C.; www.energy.gov) last month to scale up its Green Parabolic Trough Collector, a solar thermal technology that cuts construction costs by half compared…
