Modernized pumps and advanced controls improve accuracy and repeatability of liquid-dosing systems Whether the application is dosing chemicals for process or water treatment, whether it’s batch or inline dosing and whether it’s continuous or intermittent flow, at its heart, successful…
Plant Watch Ineos breaks ground for Bayport ASA plant August 12, 2019 — Ineos Styrolution GmbH (Frankfurt, Germany; www.ineos-styrolution.com) hosted a groundbreaking ceremony for its new acrylonitrile styrene acrylate (ASA) plant in Bayport, Tex. The new site, which is designed…
Although it contains many valuable metals, electronic waste (e-waste) is an exceedingly difficult material stream to process, and the vast majority of e-waste is not recycled. EnviroLeach Technologies Inc. (Vancouver, B.C.; www.enviroleach.com) is currently preparing to start up a first-of-its-kind…
Oxysulfide semiconductors have narrow bandgaps — a property that makes them suitable photocatalysts for water splitting under irradiation with visible light (640 nm wavelength). That’s because the electronegative sulfide ions negatively shift the valence band edges of the corresponding oxides.…
Many countries are now making rapid advances in hydrogen energy technologies and strategy, and the rest of the world has much to learn from their experience, according to a new report — Advancing Hydrogen — compiled by a team from…
Microplastics — a subgroup of plastics with an effective diameter less than 5 mm — are ubiquitous pollutants. They adsorb organic and metal pollutants that are ingested by aquatic organisms, and accumulated all the way up the food chain. Using…
The water-gas shift reaction (WGS; in which water vapor is reacted with carbon monoxide over a copper-chromium-iron-oxide catalyst to yield hydrogen and CO2) is of paramount importance to the chemical industry, as it is a primary route to producing H2…
Recently, Tosoh Corp. (Tokyo, Japan; www.tosoh.com) has applied a new, proprietary oxocatalyst in the oxychlorination process for making ethylene dichloride (EDC) from ethylene, HCl, and O2 in its vinyl chloride monomer (VCM) manufacturing process. The performance boost anticipated from simulation…
After four years of project development and execution, the new PolyFuel unit at Petrobrazi petroleum refinery in Romania has been started-up and is fully functional since April 2019. Based on the PolyFuel technology licensed by Axens (Rueil-Malmaison, France; www.axens.net), the…
The seemingly boundless versatility of additive manufacturing makes it an area ripe for fast evolution, but critical industrial applications also demand verification and reliability There is no doubt that 3D printing (also known industrially as additive manufacturing; AM) has set…
