High pressure thermophysical property data to advance natural gas processing and liquefied natural gas production. The natural gas industry needs to advance its understanding of fundamental fluid properties at extreme conditions of pressure and temperature to develop more efficient processing technologies. This project will develop the measurement technologies needed to probe key fluid properties at extreme conditions to enable more efficient process design.
Energetics and dynamics of solvated biologically relevant molecules using liquid microjet and ion imaging technologies. The shape of many biomolecules in solution plays a critical role in determining their biological activity and function. It is known that the bonds that form between the biomolecules and the water solvent control this shape. However, very little is known about the strength and structure of these bonds at different sites around the biomolecule. Many experiments have informed u ....Energetics and dynamics of solvated biologically relevant molecules using liquid microjet and ion imaging technologies. The shape of many biomolecules in solution plays a critical role in determining their biological activity and function. It is known that the bonds that form between the biomolecules and the water solvent control this shape. However, very little is known about the strength and structure of these bonds at different sites around the biomolecule. Many experiments have informed us about the strength of the bonds, others have told us where the bonds occur. This project will provide both pieces of information for the first time, allowing us to better understand, and therefore control, biological function. This work will assist in the development of new biotechnology processes, especially in the emerging area of proteomics.Read moreRead less
Avoiding cryogenic solids formation in liquefied natural gas production. This project will determine how and under what conditions cryogenic hydrocarbon solids form during liquefied natural gas (LNG) production, which often cause expensive unplanned plant shutdowns. New sensors will be developed to understand and monitor the conditions which cause these blockages and will be deployed into LNG plants to avoid the critical conditions.
Redox processes in Bayer liquors. Alumina, and the aluminium produced from it, are amongst Australia's most important mineral commodities, earning about $8 billion p.a. in exports. However, ongoing technological improvements are needed for Australian producers to remain globally competitive. This project addresses a key problem in alumina production - the behaviour of organic impurities - which will help to increase industrial productivity and reduce energy consumption.

Alumina, and the aluminium produced from it, are amongst Australia's most important mineral commodities, earning about $8 billion p.a. in exports. However, ongoing technological improvements are needed for Australian producers to remain globally competitive. This project addresses a key problem in alumina production - the behaviour of organic impurities - which will help to increase industrial productivity and reduce energy consumption. Insights gained from this research will also minimize the environmental and occupational health impacts of various process emissions, making the industry more sustainable.Read moreRead less
Deep ocean thermodynamics and climate change. This project aims to obtain new insights into the thermodynamic and transport properties of mixtures containing water, particularly at high pressures, that impact directly on our understanding of climate change processes.

It will be used to model saline water mixtures containing carbon dioxide, resulting in ....Deep ocean thermodynamics and climate change. This project aims to obtain new insights into the thermodynamic and transport properties of mixtures containing water, particularly at high pressures, that impact directly on our understanding of climate change processes. The project will involve the use of a polarisable potential for water which has recently been demonstrated to yield predictions of high accuracy. It will be used to model saline water mixtures containing carbon dioxide, resulting in valuable data for thermodynamic properties of the world's oceans. These data are of crucial importance for accurate climate change predictions and as such the project will have an important impact on understanding our changing environment.Read moreRead less
Fundamental Data and Thermodynamic Modelling for Cryogenic LNG Fluids to Improve Process Design, Simulation and Operation. This research will contribute to a more environmentally sustainable Australia because it will promote the use of natural gas as a fuel supply which produces significantly fewer greenhouse gases than oil or coal.

This research will contribute to a more environmentally sustainable Australia because it will promote the use of natural gas as a fuel supply which produces significantly fewer greenhouse gases than oil or coal. This project will improve the ability of engineers to reliably simulate LNG production plants as well as test new processes and technologies with the potential to increase efficiency or revenue. Consequently, the level of over-engineering and, thus, the capital and operational costs of such plants will decrease. This in turn will promote the development of Australian gas reserves, particularly for those fields currently on the margins of economic viability.Read moreRead less
Heat capacities of Bayer liquors to 300C. Alumina refining is one of Australia's most important industries, earning ~$6 billion per year export income. However, major productivity gains are required for Australian producers to remain globally competitive.

However, major productivity gains are required for Australian producers to remain globally competitive. More accurate thermodynamic calculations, covering the full plant operating range, are seen by the industry as an important way to increase productivity, minimise energy consumption and cut greenhouse emissions. To achieve these aims, we must extend current theoretical understanding and establish an experimental capability, hitherto unavailable in Australia, for measuring heat capacities and densities of solutions to temperatures as high as 300 C.Read moreRead less

More meaningful computer simulations of the Bayer process, covering conditions far beyond current plant operating ranges, are seen by Australian producers as an important way to increase future productivity, minimise energy consumption and cut greenhouse emissions. To achieve these aims, we must develop hitherto unavailable modelling capabilities for predicting the behaviour of Bayer plant liquors. The more robust thermodynamic models developed in this project will enable more realistic simulations, which are a prerequisite for innovative process design and optimisation.Read moreRead less

This research will contribute to a more environmentally sustainable Australia because it will promote the use of natural gas as a fuel supply which produces significantly less greenhouse gases than oil or coal. It will contribute to the harnessing of some of Australia's largest gas reserves, like the Gorgon field, which are contaminated with large amounts of CO2 and are not yet economically viable. The removal of N2 from natural gas will reduce the cost of producing LNG which is the only method Australia can use to access global gas markets. The new adsorbent materials developed for this work may enhance other research programmes attempting to capture and sequester CO2 from industrial flue gases.Read moreRead less
