Hypersaline industrial wastewater brines are difficult to treat. Current approaches for removing salt from such brines — such as evaporative distillation and reverse-osmosis (RO) — are problematic because evaporation is highly energy-intensive and RO cannot handle salt levels present in…
The latest valves are designed to last in challenging chemical applications, increasing uptime and safety As operational efficiency and safety continue to be top priorities in the chemical process industries (CPI), processors are demanding increased reliability from their equipment, and…
An international team, including staff from the Korea Advanced Institute of Science and Technology (Kaist; Daejeon, South Korea; www.kaist.ac.kr), led by Kaist’s professor Jeung Ku Kang, has developed a technology to analyze the gas adsorption behavior of molecules of each…
Solar desalination Researchers at Rice University (Houston, Tex.; www.rice.edu) working on nanophotonics-enabled solar membrane distillation (NESMD) have found that concentrating sunlight on small areas of the desalination membrane leads to a non-linear improvement in performance in vapor pressure, which forces…
A modular, fuel-cell-like assembly featuring specially developed microbial communities is capable of producing pure hydrogen from a wide range of organic wastes. Developed by startup company Electro-Active Technologies (Oak Ridge, Tenn.; https://electroactive.tech), the microbial electrolysis system is now in the…
An international group of scientists has created a bowl-shaped electrode that can efficiently convert CO2 into carbon-based fuels and chemicals. The group includes scientists from the University of Bath (Bath, UK; www.bath.ac,uk), Fudan University (Shanghai, China; www.fudan.edu.cn), and the Shanghai…
