New sensor, sealing and vapor-recovery technologies aim to reduce methane emissions On January 14, the Obama Administration announced a new goal to cut methane emissions from the oil-and-gas (O&G) sector by 40–45% from 2012 levels by 2025. The announcement builds…
Takahiro Yamashita and colleagues at the Institute of Livestock and Grassland Science, National Agriculture and Food Research Organization (NARO, Tsukuba, Japan; www.naro.affrc.go.jp) have developed an aerobic bioreactor that can reduce nitrous oxide emissions by nearly 90% in the treatment of…
Integration between instruments and systems allows manufacturers to align process parameters with business performance As technological advances in instrumentation and control continue to progress, processors are beginning to realize that not only can their process control system keep a watchful…
Composite coating A new composite material that prevents metal corrosion, even under extreme conditions, has been developed by researchers from the INM – Leibniz Institute for New Materials GmbH (Germany; www.inm-gmbh.de). The patented composite consists of layers of particles placed…
A new prototype lithium battery with a very thin metal anode achieves an energy density of 1,200 W-h/L at room temperature — double that of conventional Li-ion batteries using graphite anodes. The prototype battery, developed by Massachusetts Institute of Technologys…
Chemists from Rice University (Houston; www.rice.edu) are developing an asphalt-based powder that holds 114% of its weight in CO2. The porous material, known as asphalt-porous carbon (A-PC) captures CO2 as it leaves a natural-gas wellhead at room temperature and at…
Praxair Surface Technologies, a division of Praxair, Inc. (Danbury, Conn.; www.praxair.com), has recently introduced a new line of ceramic aluminum coatings that are said to have the same performance as legacy chromium (VI)-containing coatings. The company’s SermeTel CF and SermaLoy…
Atom transfer radical polymerization (ATRP) is a relatively new process to form carbon-carbon bonds of well-defined polymers. Since its discovery in 1995, ATRP has been performed using transition-metal complexes, such as those of copper. This feature has limited the application…
Construction has been completed on a trailer-mounted pilot plant that will produce substitute natural gas (SNG) from the products of biomass gasification (H2, CO2 and CO). Built by researchers from the Karlsruhe Institute of Technology (KIT; www.kit.edu) as part of…
Adipic acid, a precursor for the synthesis of nylon, is usually produced through nitric acid oxidation of cyclohexane, a process which has disadvantages, such as the emission of nitrous oxide — a greenhouse and ozone-depleting gas — as well as…
