Print the filter shape needed

An adaptable sintered filter element that is manufactured by 3D printing will be introduced this month at the Powtech exhibition (September 27–29; Nuremberg, Germany). Developed by Herding GmbH Filtertechnik (Amberg, Germany; www.herding.com), Omikron is an adaptable sinter-plate filter element that…

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…

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…

Silicate-rock-based material can replace flyash in cement, lowering costs and CO2

Flyash, a waste byproduct from coal burning, has been used effectively as a supplementary cementitious material (SCM) in Portland cement to displace a portion of the cement and lower the CO2 emissions associated with cement making. But because coal burning…
