Anti-fouling pre-treatment for membranes
Researchers at the Korea Institute of Science and Technology (KIST; Seoul, South Korea; www.kist.re.kr) led by Seongpil Jeong have developed a pre-treatment method for membrane distillation desalination processes that involves adding magnesium to seawater to prevent scale formation (anti-fouling) on the membrane. » |

A new trace-moisture analyzer harnesses the power of MOFs
Harnessing the optical characteristics of a metal-organic framework (MOF) material, Taiyo Nippon Sanso Corp. (TNSC; Tokyo; www.tn-sanso.co.jp) has developed a new trace moisture analyzer for nitrogen gas that is said to be more compact, sensitive, reliable and faster than current technologies for industrial-gas moisture analysis. » |

Rosemount Flame Detectors detect fuel and gas fires at long distances with the highest immunity to false alarms. These detectors rely on line-of-sight detection of the radiation emitted in the spectral bands to determine if a flame is real. Depending on the device, it can reliably detect hydrocarbon-based fuel and gas flames as well as hydrogen flames. All flame detector models feature heated optics, automatic built-in-test, false alarm immunity, and real-time diagnostics.

Filtering out and detoxifying hexavalent chromium from water
Chemists from the Swiss Federal Institute of Technology Lausanne (EPFL; Switzerland; www.epfl.ch) have developed “sponges” designed to capture various target substances, such as gold, mercury and lead, dissolved in solution. Now, they have developed one for capturing toxic hexavalent chromium from water. »
Progress on a longer-lasting catalyst for coke-free CO2 reduction
One of the main problems in the conversion of greenhouse gases, such as carbon dioxide and methane, into liquid fuel or hydrogen is the development of coke- and sintering-resistant catalysts. Nickel on magnesium oxide (Ni/MgO) has long been identified as a suitable catalyst, but rapid coke formation and sintering have prevented its use at an industrial scale. Now a group of researchers claims to have overcome those problems. »
This self-sustaining cell makes electrolysis more practical
A team of researchers from Idaho National Laboratory (INL; Idaho Falls; www.inl.gov) has developed a new electrode material that simplifies hydrogen generation and energy storage via protonic, ceramic electrochemical cells (PCECs). Conventional electrolysis technologies use electricity to efficiently split water, but are limited by their extremely high operating temperatures — often as high as 800ºC, which make them cost-prohibitive for wide market penetration. » |
New process for safer and continuous magnesium production to be piloted
Because of its abundance, light weight and easy alloying, magnesium metal has great potential for components in the automotive, aerospace and military industries. However, the two existing magnesium production processes — the Pidgeon process from ore and electrolytic process from MgCl — both have major drawbacks with safety and environmental impact. Now, a pilot plant currently in the design phase will demonstrate a new Mg production process that dramatically reduces the safety and environmental problems compared to existing processes. »

| Industrial Water Use and Treatment Guidebook |
| Industrial uses of water are many: in cooling towers, condensers and boilers, as process and wash fluids and more. Treatment of water is often needed, to prevent corrosion for example, and for reuse or disposal. With water scarcity as a serious global challenge, efforts to conserve, treat and reuse water, as well as to reclaim water via desalination are leading to new technological advancements. This collection of articles presents a timely and informative overview of global efforts on industrial water-related topics. It includes articles on cooling water, boilers, water conservation, wastewater treatment, some of the latest technological advancements and more. |
