Many industrial processes involve phenol, but its toxic nature means that it must be effectively removed from waste streams prior to any subsequent biological treatment steps. Phenol can be removed via evaporation, but this method is quite energy-intensive. Alternatively, the…
In a variety of industrial applications, crystallization technologies contribute to the circularity of manufacturing processes and supply chains Crystallization is a major unit operation in the chemical process industries (CPI), typically used for separating and purifying materials in a wide…
Honeywell UOP (Des Plaines, Ill.; www.uop.com) has adapted its recycle-split-vapor (RSV) technology for natural-gas liquid (NGL) recovery into a new, modular offering, RSV2, which enables quick retrofitting of existing gas-processing plants with minimal downtime. “The RSV2 technology can increase ethane…
Solvay S.A. (Brussels, Belgium; www.solvay.com) recently announced a new commercial process for synthetic eugenol (diagram), a derivative of phenol, whose natural version is extracted from clove oil obtained from dried flower buds of clove trees grown in Indonesia and Madagascar.…
Xylene isomers are usually derived from the catalytic reforming of crude oil, and require costly methods to separate them from each other, including distillation, fractional crystallization and adsorption in high-temperature and high-pressure environments. “The separation of xylene’s isomers requires much…
In Sweden, incineration of household waste in waste-to-energy (WtE) plants is common, and generates around 250,000 metric tons (m.t.) of flyash every year. The rest of Europe accounts for around ten times that amount. Most of this waste is landfilled,…
Advanced sensors are crucial to any predictive maintenance strategy, and often these sensors must be quickly installed into difficult-to-reach spaces. A novel nanomaterial technology enables predictive sensors that can be “printed” onto flexible stickers. These stickers can be easily attached…
Plant Watch Linde to build world’s largest PEM electrolyzer in Germany January 14, 2021 — Linde plc (Guildford, U.K.; www.linde.com) will build, own and operate the world’s largest proton-exchange membrane (PEM) electrolyzer plant at the Leuna Chemical Complex in Germany.…
Ammonia catalyst Clariant Catalyst (Munich, Germany; www.clariant.com) and Casale SA (Lugano, Switzerland; www.casale.ch) have developed a new ammonia synthesis catalyst for sustainable CO2 reduction. Based on Clariant’s AmoMax 10 — a wüstite-based alternative to traditional magnetite-based catalysts — the AmoMax-Casale…
