Sludge dewatering Last month, Metso Corp. (Helsinki, Finland; www.metso.com) introduced what it claims to be the worlds first advanced solution — both measurements and control system — to optimize sludge dewatering at wastewater treatment plants. The Metso SDO (sludge…
A stabilized palladium catalyst system that can be used for making materials for organic solar cells and pharmaceuticals has been developed by the research groups of of Yoichi Yamada at Riken (Wako city; www.riken.jp) and Shigenori Fujikawa at the International…
Acetic acid from syngas A new process for the production of acetic acid claims to be more efficient and cost-effective than current technologies. Carbonylation of methanol has been the leading acetic acid technology for several decades, but BP plc…
The effluent discharged by domestic industries in Japan amounts to approximately 11.1 billion ton/yr. Most of this waste is comprised of relatively low concentrations of organic matter. Today, most of this effluent is treated by aerobic biotreatment (activated sludge). However,…
A research team from the University of Western Australia (Perth; www.uwa.edu.au), led by professor Dongke Zhang, has pioneered the application of higher plants for new-generation biofuel production. Metabolic engineering of Arabidopsis thaliana — a small flowering plant native to Europe…
Petroleum refineries generate power from a number of sources, including cogeneration plants and steam networks. Generally, steam networks use turbines to improve operational reliability, specifically as drivers for rotating equipment. Due to increasing energy costs, it is essential to maximize…
A new process for producing monoethylene glycol (MEG) from synthesis-gas-based feedstocks is nearing completion of extensive pilot plant operation, according to developers Eastman Chemical Co. (Kingsport, Tenn.; www.eastman.com) and Johnson Matthey Davy Technologies Ltd. (London, U.K.; www.davyprotech.com). The technology enables…
Low-grade nickel (less than 1.5 wt.%) laterite ores represent about 70% of global reserves but account for only 40% of nickel production. Increasing demand for nickel in recent years has created the need to process such ores. Atmospheric acid leaching…
Pilot plant operation has been completed for a process that produces the fertilizer potassium sulfate from the mineral polyhalite, a hydrated sulfate of potassium, magnesium and calcium. The process, developed by Intercontinental Potash Corp. (ICP; Golden, Colo.; www.icpotash.com), resurrects a…
The National Food Research Institute (NFRI) of the National Agriculture and Food Research Organization (NARO; Tsukuba City, Japan; www.naro.affrc.go.jp) has developed an enzymatic pretreatment process for producing highly concentrated sugar solution from fibrous materials containing rice straw and starch. The…
