Controlling hydrate slurry flow to enable deepwater oil and gas production. This project aims to investigate the plugging of hydrate slurries in pipelines to determine under what conditions they will flow satisfactorily without forming a blockage. Hydrate blockages are expensive and hazardous occurrences in oil and gas operations, so current prevention systems aim to avoid hydrate formation altogether through over-design. These over-designed hydrate prevention systems are extremely expensive to ....Controlling hydrate slurry flow to enable deepwater oil and gas production. This project aims to investigate the plugging of hydrate slurries in pipelines to determine under what conditions they will flow satisfactorily without forming a blockage. Hydrate blockages are expensive and hazardous occurrences in oil and gas operations, so current prevention systems aim to avoid hydrate formation altogether through over-design. These over-designed hydrate prevention systems are extremely expensive to build and costly to run during the operations phase. The project intends to examine the behaviour of hydrate slurry flow as a function of the oil's properties, amount of water and degree of turbulence. Outcomes are intended to be a sophisticated approach to avoiding hydrate blockages that is safe but more efficient and less costly.Read moreRead less
Improvements and Optimisation of Water Electrolysis for Hydroxy Gas Production for Metal Cutting Applications. The current technique for metal cutting mainly uses oxygen-acetylene flames, which means for the large number of Australian remote communities oxygen and acetylene bottles have to be transported from major cities. This incurs significant transport costs and associated environmental emissions and presents major safety concerns. Hydroxy flames using electrolysis of water can alleviate the ....Improvements and Optimisation of Water Electrolysis for Hydroxy Gas Production for Metal Cutting Applications. The current technique for metal cutting mainly uses oxygen-acetylene flames, which means for the large number of Australian remote communities oxygen and acetylene bottles have to be transported from major cities. This incurs significant transport costs and associated environmental emissions and presents major safety concerns. Hydroxy flames using electrolysis of water can alleviate these problems and, by utilising renewable electricity, the new technology to be developed in this research will transform tens of thousands of Australian metal workshops to be more environmentally friendly, safer and more cost-effective, thus contributing to the development of an environmentally sustainable Australia.

Are acidic mine lakes usable as regional water resources? After the de-commissioning of open-cut mines, the voids frequently fill with water. In Australia, hundreds of mine lakes will develop over the next ten years and beyond. When the base mineralogy is pyritic the water can become highly acidic with high concentrations of dissolved metals. These mine lakes frequently exist in regions where water resources are in short supply. This project will investigate possible strategies to remediate such ....Are acidic mine lakes usable as regional water resources? After the de-commissioning of open-cut mines, the voids frequently fill with water. In Australia, hundreds of mine lakes will develop over the next ten years and beyond. When the base mineralogy is pyritic the water can become highly acidic with high concentrations of dissolved metals. These mine lakes frequently exist in regions where water resources are in short supply. This project will investigate possible strategies to remediate such lakes and assess the possibility of using mining lakes as valued water resources in these regions. The primary outcome of the research will be improved management of the lakes for optimal long term water quality.Read moreRead less
