Biotrend Energy to build waste-plastics recycling plant in Turkey

Honeywell says that Biotrend Energy (Istanbul, Turkey) will apply Honeywell’s UpCycle process technology in Biotrend Energy’s planned plastics recycling factory in Turkey. The facility will convert mixed waste plastics into recycled polymer feedstock (RPF), enabling the development of a circular…

thyssenkrupp Uhde wins order for low-emission coke oven battery in Japan

Thyssenkrupp Uhde (Dortmund, Germany) has won an order from Nippon Coke & Engineering Co., Ltd. (NCE; Tokyo, Japan) to build and supply a new low-emission, top-charge coke oven battery in Japan. The new battery will be installed at the Kitakyushu…

Siemens commissions one of Germany’s largest ‘green’ hydrogen generation plants

In Wunsiedel, Upper Franconia, one of Germany’s largest green hydrogen generation plants has been planned digitally and commissioned by Siemens AG (Munich, Germany), demonstrating the key role hydrogen can play in Germany’s energy future. Around one year after the official…

Facts At Your Fingertips: Gas Dispersion in Liquids

Injecting gases through a diffuser into a liquid is an important aspect of many operations in the chemical process industries (CPI). Important applications include dissolving reactant gases into a liquid phase for further reaction (such as in hydrogenation, oxidation, ozonation),…

Zero-CO2 ethane cracker technology is available commercially

A next-generation ethane-feed steam cracker designed by Lummus Technology (Houston; www.lummus.com) has the ability to achieve zero carbon dioxide emissions in the production of ethylene. The zero-CO2 design utilizes Lummus SRT pyrolysis furnaces and a state-of-the-art product-recovery system. Lummus improved…

Extracting pressurized hydrogen from ammonia, methane and biogas

Proton ceramic cells that couple endothermic steam reforming with heat from electrochemical gas separation and compression have been scaled up. These cells, developed by CoorsTek Membrane Sciences AS (Oslo; www.coorstek.com), the University of Oslo (both Norway; www.uio.no) and the Institute…

Energy costs cut by 50% for high-strength aluminum alloys

Aluminum alloy 7075 has excellent mechanical properties, including high strength for lightweighting applications, but its production process is energy intensive, which raises costs and limits its use. Now, scientists at Pacific Northwest National Laboratory (PNNL; Richland, Wash.; www.pnnl.gov) have developed…

Chementator briefs

Zero-spin Silicon Natural silicon consists of three isotopes: 28Si (92.2%) and 30Si (3.1%) — each with zero electron spin state — and 29Si (4.7%) with a spin state of one half. The presence of 29Si in concentrations above 500 parts…

A step closer to transition-metal catalysis with aluminum

Chemists from the Institute of Inorganic and Analytical Chemistry at the University of Freiburg (Germany; uni-freiburg.de) have synthesized a cationic, low-valence aluminum complex salt. “So far, there has been only one example of a cationic, low-valent aluminum compound, but it…

A new electrolyte supercharges sodium-ion batteries

Sodium-ion batteries have many advantages over lithium-ion batteries due to sodium’s abundance and low cost. However, there are several performance challenges to overcome with sodium-ion batteries because there is typically a tradeoff between energy density and lifecycle. Now, a research…
