    Minor components trapped in distillation columns can react to form solids that cause major problems. The conventional responses to this situation focus upon dealing with the solids after they have become formed. A better strategy consists of preventing or minimizing the solids formation in the first place, by changing the column operating conditions.   Understanding the situation The...

Next month, Mekorot, Israel National Water Company Ltd. (Tel Aviv, Israel) will start up what is claimed as the world’s first ion-exchange system for selectively removing boron from potable water. The plant, designed and constructed by Treitel Chemical Engineering Ltd. (Tel Aviv; edlinks.che.con/5827-532), will treat 6,500 m3/d of reverse-osmosis-product water at Mekorot’s brackish water...

A gas-liquid nozzle that reduces the size of the gas bubbles blown into a liquid — thus increasing the rate at which the gas is absorbed into the liquid — has been developed by a research team led by Jie Wu at CSIRO Manufacturing and Infrastructure Technology Div. (edlinks.che.com/5826-531), in collaboration with CPE Ltd (Chemical Plant & Engineering; both Melbourne, Victoria, Australia...

Ultrasound Brewery Co. (Naruto, Japan; edlinks.che.com/5825-535) has developed a process that separates the water from dilute solutions of alcohol to achieve 99.5%, without using conventional evaporation or distillation. The company has tested the process in a pilot plant that produces 600–700 L/d of 99.5% ethanol from a 10–15% solution. The process, which combines irradiation with ultrasound...

A simple tank-and-siphon system for removing oil from wastewater has been launched internationally by an engineering team from the University of New South Wales (UNSW; Sydney, Australia; edlinks.che.com/5825-541). Called the Extended Gravity Oil Water Separator (EGOWS), it is described as an improvement on the American Petroleum Institute (API) gravity separator, in that it reduces the oil content of the...
