Swirling turbulent pipe flow technology for drying brown coal. This project aims to understand the complex fluid mechanicalprocesses in a brown coal drying machine. Brown coal from the Latrobe Valley contains about 70 percent moisture, which must be reduced for it to be used efficiently in power stations.

This project aims to understand the complex fluid mechanicalprocesses in a brown coal drying machine. Brown coal from the Latrobe Valley contains about 70 percent moisture, which must be reduced for it to be used efficiently in power stations. Utilising cutting-edge techniques in laboratory and field measurements together with advanced computational methods in fluid mechanics, the project intends to further knowledge in swirling turbulent flows, particle transport and vortex breakdown. The result of this research is expected to produce a drier brown coal, leading to a cleaner environment and an increase in Australian coal value. Read moreRead less
Improving performance of solvent extraction equipment for the minerals processing industry. This project will develop a fundamental understanding of how a new type of solvent extraction column, which was recently introduced to the mining industry, responds to changes in process conditions and operating parameters. This will enable the potential for optimal and efficient use of these assets and ensure a competitive advantage for Australia's biggest export earner.
TRANSIENT VIBRATION IN PIPELINE SYSTEMS. Although the threat of transient vibration to the safety of pipeline systems has been widely recognised, neither the coupling characteristics in transient wave propagation are clearly understood, nor accurate tools are available for analysing them. The aims of this project are to develop effective analytical and experimental methods, to study the interactions between transient waves of different types at pipe joints and bends, and to experimentally charac ....TRANSIENT VIBRATION IN PIPELINE SYSTEMS. Although the threat of transient vibration to the safety of pipeline systems has been widely recognised, neither the coupling characteristics in transient wave propagation are clearly understood, nor accurate tools are available for analysing them. The aims of this project are to develop effective analytical and experimental methods, to study the interactions between transient waves of different types at pipe joints and bends, and to experimentally characterise the transient excitations. The understanding and techniques developed from this project hold promise in providing reliable tools for safe design of complex pipeline systems in petroleum, chemical and refinery industries.Read moreRead less

This project aims to study the briquetting processes of fine powders, and the preparation and utilization of new brown coal (lignite)–iron ore composite briquettes in a blast furnace. Lignite is a low-cost and abundant resource, and could be used in an emerging carbon-iron ore composite briquette for low-cost ironmaking. This project will perform multi-scale numerical studies, supported by lab/industry-scale experiments, to produce models and control strategies. Anticipated outcomes include better design and control of briquette's preparation and utilization in ironmaking for further cost-cutting; a new market for brown coal; and a more competitive Australian economy.Read moreRead less

Three-dimensional flotation of fine particles. Three-dimensional flotation of fine particles. This project aims to research three-dimensional flotation of fine particles under both batch and continuous steady state conditions. In flotation, fine hydrophobic particles adhere to the two-dimensional surface of rising air bubbles, forming concentrate. In three-dimensional flotation, however, the particles adhere to and become embedded in a novel binder, forming a highly buoyant product. The process ....Three-dimensional flotation of fine particles. Three-dimensional flotation of fine particles. This project aims to research three-dimensional flotation of fine particles under both batch and continuous steady state conditions. In flotation, fine hydrophobic particles adhere to the two-dimensional surface of rising air bubbles, forming concentrate. In three-dimensional flotation, however, the particles adhere to and become embedded in a novel binder, forming a highly buoyant product. The process is very selective and arguably 1000 times faster than conventional flotation. The project is expected to provide the knowledge required to achieve scale-up, so the technology can be used to recover high value product from tailings waste, eliminating the capital impediment and possibly transforming the entire mining industry.Read moreRead less
Effectiveness of deep natural clay, compacted clay and geomembranes in limiting seepage from coal seam gas production water evaporation ponds. Australia's coal seam gas reserves exceed those of the Moomba and Bass Strait gas fields combined. Queensland's coal seam gas production already accounts for more than 50% of the state's natural gas supply, and continues to grow rapidly. The production of coal seam gas will escalate in coming years, particularly to provide a clean fuel for electricity g ....Effectiveness of deep natural clay, compacted clay and geomembranes in limiting seepage from coal seam gas production water evaporation ponds. Australia's coal seam gas reserves exceed those of the Moomba and Bass Strait gas fields combined. Queensland's coal seam gas production already accounts for more than 50% of the state's natural gas supply, and continues to grow rapidly. The production of coal seam gas will escalate in coming years, particularly to provide a clean fuel for electricity generation and feed stock for liquefied natural gas to supply rapidly growing markets in Asia. As gas production increases, so too does the generation of saline water. This research will ensure that the evaporation of the saline water does not impact the underlying Great Artesian Basin, so that coal seam gas production may continue and grow.Read moreRead less
Maximizing the kinetics of flotation processes. The purpose of this project is to develop a new flotation technology that can be operated at feed rates vastly higher than existing technologies. The technology will be applicable to low grade feeds often discarded to tailings, delivering billions of dollars in additional exports of Australian resources and contributing to the growth in the mining services sector.
Development of a Trickle Filter for Treating Sour Water from Oil Shale Processing Plants. Oil is extracted from oil shale by pyrolysing pre-dried crushed shale. Despite drying , the shale retains a residual moisture level of approximately 5% which ultimately ends up as an aqueous phase in the condensate stream from the pyrolysis process. This aqueous phase, know as sour water, contains a range of organic compounds, including carboxylic acids, nitorgen heterocyclics and ketones. This aim of thi ....Development of a Trickle Filter for Treating Sour Water from Oil Shale Processing Plants. Oil is extracted from oil shale by pyrolysing pre-dried crushed shale. Despite drying , the shale retains a residual moisture level of approximately 5% which ultimately ends up as an aqueous phase in the condensate stream from the pyrolysis process. This aqueous phase, know as sour water, contains a range of organic compounds, including carboxylic acids, nitorgen heterocyclics and ketones. This aim of this proposal is to develop trickle filters to treat the sour water. The biofilms that develop in trickle filters are ideal for supporting slow growing microbial species. Research is needed to transfer native microorganisms in the oil shale desposit to the durable gravels that will be used in the filter.Read moreRead less
