A step toward ammonia production at ambient conditions
Many investigations are ongoing to achieve ammonia synthesis at energy-saving mild conditions instead of the high temperatures and pressures (500°C, 300 atm) required by the commonly used Haber-Bosch process, which consumes more than 1% of the world’s power production. Now,…
Ceramic membranes and O3 combine to treat wastewater
High fluxes and micro-contaminant reduction have been achieved in a 2.5-m3/h pilot plant to test the performance of ceramic membranes and ozonation in treating wastewater at Melbourne Water’s (www.melbournewater.com.au) Eastern Treatment Plant. The project, to be completed in a few…
Non-toxic flame retardants
Researchers from EMPA, the Swiss Federal Laboratories for Materials Science and Technology (St. Gallen, Switzerland; www.empa.ch) have developed organic phosphorous-containing compounds, called phosphoramidates, that show promise as non-toxic alternatives to conventional halogenated flame retardants, such as tri(chloropropyl)phosphate (TCPP) or polybrominated…
Spotlight on Petroleum Refining in India
The petroleum refining sector in India plays a vital role in the country’s industrial development and provides a major source to meet India’s energy requirements. Today, the refining sector satisfies about 30% of the total energy demand of India […
A one-pot process to pretreat and saccharify biomass
Researchers from the U.S. Dept. of Energys Joint BioEnergy Institute (JBEI; Emeryville, Calif.; www.jbei.org) have reported the first demonstration of a one-pot, wash-free process for the ionic-liquid pretreatment and saccharification of switchgrass — a leading potential biofuel feedstock. By combining…
Successful implementation of a new extractive-distillation technology for aromatics recovery
AMT International Inc. (Plano, Texas; www.amtintl.com) and LG Chem, Ltd. (Seoul, Korea; www.lgchem.com) have successfully converted an existing sulfolane liquid-liquid extraction (LLE) unit at LG Chem’s Yeosu plant using a new extractive-distillation (ED) process for aromatics recovery. This technology was…
Cement technology increases strength and lowers emissions footprint
Cement manufacturing is a major source of greenhouse gas emissions due to two factors: carbon dioxide is released when calcium carbonate calcines to lime (CaO) in the cement manufacturing process; and cement kilns are operated at temperatures of 1,500°C, which…
A direct, one-step enzymatic hydroxylation of benzene to phenol
The selective, one-step biocatalytic hydroxylation of benzene to phenol — at ambient pressure and temperature — has been demonstrated by professors Yoshihito Watanabe and Osamu Shoji at Nagoya University (Nagoya, Japan; bioinorg.chem.nagoya-u.ac.jp). The achievement was made using a wild-type of…
September Chementator Briefs
Solar steam The Middle East’s first solar enhanced-oil-recovery (EOR) project was recently commissioned by Petroleum Development Oman (PDO; Muscat, Oman; www.pdo.co.om). The project uses Enclosed Trough technology from GlassPoint (Fremont, Calif.; www.glasspoint.com) to produce an average of 50 ton/d of…
Linde to help commercialize an oil-from-algae process
Sapphire Energy, Inc. (San Diego, Calif.; www.sapphireenergy.com) and The Linde Group (Munich; www.linde.com) have signed an agreement, with a minimum span of five years, to commercialize Sapphire’s process for producing crude oil from algae. The agreement expands an existing partnership…
