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 of these ores presents difficulties due to the presence of high-acid-consuming serpentinized and clay minerals, leading to pulp gelation and poor mixing, and...

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 route to K2SO4 that was first explored in a push to develop a domestic source of potash after a German embargo in...

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 Corp. (Perth; www.newenergycorp.com.au), and will employ low-temperature gasification technology invented and developed by Western Australian company Entech Renewable...

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 (1,000 rpm instead of 1,500 rpm), so the wear-rate of components is reduced. This leads to a...

  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 (London, U.K.; www.bp.com) has introduced the new three-step SaaBre process to produce acetic acid directly from synthesis gas (syngas; a mixture of H2...

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, activated sludge treatment not only consumes large amounts of electric power needed to run blowers or fans, but it also produces...

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 and Asia, which was the first plant to have its genome sequenced — caused the plant to produce triterpene...

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 the power-generation capabilities of steam networks. This article presents a spreadsheet-based optimization model...
