A spray-drying technology that applies an electrical charge to feedstock as it exits the atomizing nozzle allows significant reductions in processing temperature and can eliminate downstream processing steps. The charge application can improve control over particle morphology, lengthen shelflife of…
Recycling sachets Later this year, Unilever (London, U.K.; www.unilever.com) plans to open a pilot plant in Indonesia to test the long-term viability of its new technology for recycling plastic sachet (small bags) waste. The process, called CreaSolv, has been developed…
Plant Watch Ineos announces plans to build new PDH plant, increase ethylene capacity June 12, 2017 — Ineos (Rolle, Switzerland; www.ineos.com) announced plans to construct a propane dehydrogenation (PDH) unit in Europe. The plant will produce 750,000 metric tons per…
Membrane distillation (MD) — a thermal desalination technique used for recovering pure water from concentrated salt solutions — is hampered by high energy consumption, low single-pass recovery rates and by the need to use expensive heat exchangers to handle the…
Many ZnO@TiO2 core-shell nanorod arrays (the notation means ZnO is the core inside the TiO2 shell) with good photocatalytic activity have been designed and synthesized. There has been an increasing interest in the design and synthesis of those arrays to…
Carbon fibers, an increasingly essential component for lightweight materials, are typically made from polyacrylonitrile (PAN) in a three-step process consisting of oxidation/stabilization, carbonization and surface treatment/sizing. 4M Industrial Oxidation, LLC (Knoxville, Tenn.; www.4mio.com) intends to commercialize a technology to produce…
An overview of how the chemical process industries are looking to the IIoT to help form new business models in a competitive environment Today, technological advances are being made and implemented at an accelerated pace that is quickly changing the…
Predictive process models enable more efficient operations and higher-value products When they hear the words “process modeling,” some may envision an engineer sitting in front of a laptop waiting for a distillation column flowsheet to converge. While flowsheet simulations are…
New motors and drives provide energy efficiency and reliability in chemical applications Always on the lookout for ways to reduce downtime and energy costs, chemical processors are turning to advanced motors and drives to help achieve these goals. Sometimes as…
An international group of researchers, coordinated by the Institute of Solar Research of the German Aerospace Center e.V. (DLR; Cologne, Germany; www.dlr.de), is developing a sulfur-based storage system for solar power. Large-scale chemical storage of solar power and its overnight…
