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.
Lowering membrane fouling by matching pre-treatment to membrane type. Delivery of potable and recycled water to communities and industry increasingly uses membrane treatment to ensure high standards of water quality, particularly as water scarcity leads to the use of poor quality water sources. Fouling of membranes occurs as water is treated, adding expense and complexity to the process. Reducing fouling will lower the cost of water treatment and improve the economics of treating water in smal ....Lowering membrane fouling by matching pre-treatment to membrane type. Delivery of potable and recycled water to communities and industry increasingly uses membrane treatment to ensure high standards of water quality, particularly as water scarcity leads to the use of poor quality water sources. Fouling of membranes occurs as water is treated, adding expense and complexity to the process. Reducing fouling will lower the cost of water treatment and improve the economics of treating water in smaller systems at source. This will enable greater reliability of localised treatment, which will reduce pumping requirements and decrease both cost and carbon emissions. Read moreRead less
Gas-phase and catalytic reaction of halons under reducing conditions. Halons are ozone-depleting substances, but their use continues in most countries. This project pursues techniques to convert, rather than destroy, halons into benign and useful products. The aims of this project are to gain a fundamental understanding of the reactions of the most commonly used halons, 1301, 1211 and 2402, and perform a detailed examination of catalytic processes for conversion of halons to HFCs. The primary ....Gas-phase and catalytic reaction of halons under reducing conditions. Halons are ozone-depleting substances, but their use continues in most countries.

The primary outcome from the study will be the development of a process specifically designed to convert halons into useful products. This will assist with efforts to phase out continued halon use.Read moreRead less
Transformation of halons and CFC to valuable products through their reaction with methane. Halons and CFCs are well known as ozone depleting substances (ODS). This project pursues the development of a novel process to transform stockpiles of halons and CFCs into vinylidene difluoride (C2H2F2). Vinylidene difluoride is a highly valued commodity, used in the synthesis of heat resistant materials. The primary aim of this research is to gain understanding of the role of catalysts during conversion o ....Transformation of halons and CFC to valuable products through their reaction with methane. Halons and CFCs are well known as ozone depleting substances (ODS). This project pursues the development of a novel process to transform stockpiles of halons and CFCs into vinylidene difluoride (C2H2F2). Vinylidene difluoride is a highly valued commodity, used in the synthesis of heat resistant materials. The primary aim of this research is to gain understanding of the role of catalysts during conversion of CFC 12 and halon 1211 into the desired reaction product. The signifigance of the project is that it will facilitate development of a process for non-destructive treatment of ozone depleting substances. The major outcome of the proposed research is it will lay the technical foundation for the development of an energy efficient process to convert rather than destroy these ODS.Read moreRead less

The project aims to generate viscoelastic soft materials with programmable anisotropy using aqueous suspensions of colloidal rods that have tunable surface coatings. The project expects to generate new knowledge in the rheology and structural characteristics of this unique class of materials. A key innovation is the use of charge-directed polymer self-assembly to control colloidal interactions, suspension rheology and phase behaviour. The intended outcome is spatial control over the orientation of nanostructures, potentially mimicking the structural hierarchy found in nature. This should provide significant benefits to the creation of viscoelastic materials with complex rheology as well as structural, mechanical and optical heterogeneity.Read moreRead less

Fires of pesticides: New source of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/F) in the environment. This project will quantify the emission of carcinogenic pollutants, produced as a consequence of intended and unintended combustion of pesticides and pesticide-contaminated biomass.

This project will quantify the emission of carcinogenic pollutants, produced as a consequence of intended and unintended combustion of pesticides and pesticide-contaminated biomass. The project will identify specific pesticides and agricultural practices (such as burning of sugar cane prior to harvest or burning biomass contaminated with pesticides for energy recovery) which may become regulated in Australia. The research will benefit Australia socially, by reducing the emissions of polychlorinated dibenzo-p-dioxins and dibenzofurans and thus protecting the environment and the population, and economically by identifying pesticides that do not produce pollutants in combustion processes and thus do not contaminate biomass intended for energy recovery.Read moreRead less
University of Queensland/Arizona State University partnership to design industrially suitable zeolite membranes for desalination. For desalination, the highest costs are organic-based membrane replacement (lasting ~1 year) and energy requirement. Functionalised zeolitic membranes are low-cost, high performing, chemically tolerant and thermally stable. New zeolite membranes in principle could perform the separation outlasting their organic counterparts, while at the same time offering major energ ....University of Queensland/Arizona State University partnership to design industrially suitable zeolite membranes for desalination. For desalination, the highest costs are organic-based membrane replacement (lasting ~1 year) and energy requirement. Functionalised zeolitic membranes are low-cost, high performing, chemically tolerant and thermally stable. New zeolite membranes in principle could perform the separation outlasting their organic counterparts, while at the same time offering major energy reductions from higher fluxes. Current zeolite membrane research for desalination however is lacking. The proposed team offers experience in bringing highly significant lab scale technologies to industrial scales. The outcomes will address mutual priorities between Australia and USA for reliable low cost supply of fresh water.Read moreRead less
