Novel gas-liquid columns for liquefied natural gas (LNG) production. This project aims to design distillation and absorption columns, perhaps the most important unit operations in a liquefied natural gas (LNG) plant, and whose optimization is integral to overall performance of any LNG plant. This project will use 3D printers to rapidly prototype concepts of columns and their internals, and test them using flow characterization tools and numerical models. The final outcome of the project will be a set of designs of the columns, which should be more efficient, safer and cheaper to operate, and have smaller physical and environmental footprints, thus helping the Australian LNG industry to stay globally competitive.Read moreRead less

Understanding mud pumping in heavy haul railroads. This project aims to examine the factors that cause mud pumping and evaluate the effectiveness of sub-surface drainage to prevent rail track instability. Fast heavy haul operations (such as loads used in mining and agriculture) impart repeated loads on the natural formation that can result in mud pumping. If the build-up of water pressure becomes excessive this can cause track failure. Through an experimental program and field study, the mechani ....Understanding mud pumping in heavy haul railroads. This project aims to examine the factors that cause mud pumping and evaluate the effectiveness of sub-surface drainage to prevent rail track instability. Fast heavy haul operations (such as loads used in mining and agriculture) impart repeated loads on the natural formation that can result in mud pumping. If the build-up of water pressure becomes excessive this can cause track failure. Through an experimental program and field study, the mechanisms of mud pumping, incorporating train loads and frequencies, will be studied, and the role of vertically installed drains will be quantified for improved practical design. The project aims to contribute to improved track longevity and reduced maintenance costs, with a corresponding boost in rail productivity.Read moreRead less
Synthesis of Activated Carbon Supported Zero Valent Iron Nanoparticles and Application to Contaminant Degradation in Benthic Sediments. Sediment contamination is a major problem in harbours and estuaries around Australia. For example, in Sydney Harbour, a total fishing ban has been implemented as a result of excessive levels of dioxins and benzofurans in fish tissues. There is also concern at the possibility of large scale contamination of Botany Bay as a result of historic industrial activity a ....Synthesis of Activated Carbon Supported Zero Valent Iron Nanoparticles and Application to Contaminant Degradation in Benthic Sediments. Sediment contamination is a major problem in harbours and estuaries around Australia. For example, in Sydney Harbour, a total fishing ban has been implemented as a result of excessive levels of dioxins and benzofurans in fish tissues. There is also concern at the possibility of large scale contamination of Botany Bay as a result of historic industrial activity around the Bay. While dredging and on-land treatment of sediments is being adopted at the most severely contaminated sites, the cost of this approach is exorbitant. For sites where removal of contaminated sediments cannot be justified, the approach proposed in this study of a technology that entraps contaminants and enhances their in situ biodegradation is potentially a way forward.Read moreRead less

The development of low-cost photovoltaic concentrator systems will allow the large scale depoyment of these systems, both in Australia and overseas. The current size of this market is several hundred MW of electricity per year, and growing rapidly. This will have both environmental benefits (though reduced greenhouse gas emissions)as well as economic and social benefits - through the creation of empoyment opportunities in PV manufacturing and the generation of export earnings. It could be of particular benefit to remote communities requiring reliable, low cost off-grid power generation.Read moreRead less
The role of location on the effectiveness of smoke alarms. Smoke alarms in buildings are required by the Building Code of Australia (BCA), but the current requirements are less than optimal. This project will provide the basis for optimisation of smoke alarms and the number, interconnection and positioning of smoke alarms in residential buildings. This is expected to lead to reductions in fire fatalities, injuries and property loss.
