Although there are several ways to reduce the phenol concentration in industrial effluent, they each have drawbacks. Chemical treatment, such as adsorption and stripping, is fast but expensive, and the chemical degradation of phenol leads to the formation of toxic…
A new electrochemical water-treatment process developed in the laboratory of T. Alan Hatton, professor of chemical engineering at Massachusetts Institute of Technology (MIT; Cambridge; web.mit.edu), employs functionalized electrodes to selectively remove contaminants, such as pesticides and pharmaceuticals, at extremely low…
On May 31, Climeworks (Hinwill/Zurich, Switzerland; www.climeworks.com) inaugurated its — and the world’s — first commercial plant that captures CO2 directly from air. The Direct Air Capture (DAC) facility, located at the waste-utilization plant of KEZO in Hinwill, Switzerland, will…
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…
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,…
Integrated console, virtual-reality simulation offers learning for maximum, measurable training efficiency Modern techniques are being used for realistic plant training for control room operators, field operators, and operations and maintenance personnel. Simulator training has been shown to result in better…
