Construction of a large-scale waste-to-energy plant will start in the middle of next year in Port Hedland, Western Australia, and operation is scheduled to commence in the second quarter of 2015. The plant will be built by the New Energy…
Last month, Mitsubishi Heavy Industries, Ltd. (MHI; www.mhi.co.jp) and Tokyo Gas Co. (both Tokyo, Japan; www.tokyo-gas.co.jop) began marketing a jointly developed 1,000-kW gas-engine cogeneration system. Based on the conventional 930-kW system, the new systems engine operates at a reduced speed…
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…
Harvest Power (Waltham, Mass.; www.harvestpower.com) recently began operation of the first commercial-scale, high-solids anaerobic digester in North America. The facility produces biogas from food waste and yard waste in Richmond, B.C., Canada. “The anaerobic digester employs essentially the same biology…
Short-chain hydrocarbons have been produced for the first time by microbial fermentation by a research team from the Dept. of Chemical and Biomolecular Engineering at the Korea Advanced Institute of Science and Technology (KAIST; Daejeon, South Korea, www.kaist.ac.kr), led by…
