This investigation addresses the key issue of the effect of oxide formation on coke dissolution during ironmaking. A fundamental understanding of the nature of the oxide layer and its penetration by liquid metal is critical to the optimization of both traditional and new ironmaking technologies. The project will obtain kinetic data that will be used in process models to improve productivity, reduce coke consumption and reduce greenhouse gas emissions. This knowledge is particularly important for maintaining the competitiveness of Australian iron producers due to the high refractory oxide content of local coking coals.Read moreRead less

Summary
A risk-based approach to natural gas hydrates in oil and gas production. Like a cholesterol for oil and gas pipelines, gas hydrates are ice-like deposits that completely block the flow during production and are expensive to prevent as well as dangerous to remove. This proposal provides a risk-based approach to hydrate management that will increase the viability of natural gas production from fields in deep water.

Free Surface Instability and Gas Entrainment during Blast Furnace Drainage. Iron and Steelmaking operations have underpinned Australia's industry base for many years. To remain competitive in a global market BHP has undertaken considerable research and development to constantly improve process performance. An area of on-going concern is the unexpected release of gas during Blast Furnace drainage resulting in hazardous conditions for the operators and overall loss of production.

To remain competitive in a global market BHP has undertaken considerable research and development to constantly improve process performance. An area of on-going concern is the unexpected release of gas during Blast Furnace drainage resulting in hazardous conditions for the operators and overall loss of production. This project aims to identify the causes of gas release and to devise operational strategies and design modifications to prevent this occurrence. Once implemented the outcomes of the research will be a more stable operation leading to increased production and less environmental emissions.Read moreRead less
Dynamic behaviour of foams. Foam flow occurs in many industrial processes such as the fractionation of proteins and coal flotation. The proposed research will investigate transient behaviour at start-up of such processes and how the method of foam production affects process efficiency. The dispersion of liquid tracers in foam and a newly discovered phenomenon of ?upwards rippling? will be studied as it is likely that these could illuminate the physical processes that lay behind foam flow. Remova ....Dynamic behaviour of foams. Foam flow occurs in many industrial processes such as the fractionation of proteins and coal flotation.

The dispersion of liquid tracers in foam and a newly discovered phenomenon of ?upwards rippling? will be studied as it is likely that these could illuminate the physical processes that lay behind foam flow. Removal of unwanted material from a pipeline is often a major industrial problem and the ability of foams to perform this role will be assessed.Read moreRead less
Inter-metallic Inclusion Reduction in Continuous Metallic Coating. The ZINCALUMER coating process is a core business of BlueScope Steel. Operational and quality issues are being experienced due to inter-metallic particles in the liquid metal bath. The particles cause defects in the metal coating and agglomerate, resulting in periodic shutdowns to remove the dross. Both of these factors impact significantly on the profitability of the operation. In this project a new strategy is being investigate ....Inter-metallic Inclusion Reduction in Continuous Metallic Coating. The ZINCALUMER coating process is a core business of BlueScope Steel. Operational and quality issues are being experienced due to inter-metallic particles in the liquid metal bath. The particles cause defects in the metal coating and agglomerate, resulting in periodic shutdowns to remove the dross. Both of these factors impact significantly on the profitability of the operation. In this project a new strategy is being investigated, whereby the fluid mechanics and heat transfer mechanisms within the bath will allow inter-metallic particles to be continuously removed in the metal coating before they reach the critical size that adversely affects product quality. This will also reduce dross accumulation, thereby reducing shutdown time.Read moreRead less
