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…
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…
Efforts continue to make nitric-acid production more efficient with lower emissions of greenhouse gases Like the ammonia used to make it, nitric acid (NA) continues to be produced by a process nearly a century old — the Ostwald process. Although…
More sophisticated packaging equipment helps the CPI boost product quality and machine reliability When it comes to packaging their products, chemical, pharmaceutical and food processors list product quality, often directly related to health and human safety, as the top concern,…
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…
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…
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…
Efficient distillation Last month, Toyo Engineering Corp. (Toyo; Chiba, www.toyo-eng.co.jp) and Koch-Glitsch, LP (Wichita, Kan.; www.koch-glitsch.com) announced a new partnership to distribute Toyo’s energy-saving distillation system, SuperHIDiC, to new global markets in Europe and the Middle East. SuperHIDiC provides energy…
