Multi-scale Process Modelling for Intelligent Control. Processing and manufacturing systems are inherently multi-scale in their behaviour. From the molecular scale to the enterprise-wide scale. This and other attributes of the individual models create difficulties in the design and control of such systems.

Unsteady-State Operation of Slurry and Fixed-Bed Fischer-Tropsch Reactors for Improved Process Performance. The development of efficient gas-to-liquid processes via the Fischer-Tropsch reaction is the most economically viable route for the production of non-petroleum based chemicals and environmentally-friendly fuels from abundant natural gas.

The development of efficient gas-to-liquid processes via the Fischer-Tropsch reaction is the most economically viable route for the production of non-petroleum based chemicals and environmentally-friendly fuels from abundant natural gas. This investigation proposes the exploitation of both reactor and catalyst dynamics behaviour to obtain higher hydrocarbon synthesis rate and selectivity not attainable under conventional steady-state operation. With current market conditions of about US$30/bbl for crude oil, even modest process improvements of 30-60% will make the process competitive. Whilst individual national energy policy goals are promoted, the research will further strengthen closer economic and technology ties between France and Australia.Read moreRead less
Development of an integrated methodology to assess dewatering system performance in solid-liquid separation. 3D visualisations of microstructures are possible with techniques such as confocal laser microscopy and high resolution X-ray microtomography. Data obtained in-situ enable direct computation of solids assembly properties and their permeability to fluids. A specific application involving aggregate formation and sediment networks could be evaluated through micro-scale analysis combined with ....Development of an integrated methodology to assess dewatering system performance in solid-liquid separation. 3D visualisations of microstructures are possible with techniques such as confocal laser microscopy and high resolution X-ray microtomography. Data obtained in-situ enable direct computation of solids assembly properties and their permeability to fluids. A specific application involving aggregate formation and sediment networks could be evaluated through micro-scale analysis combined with robust fluid flow simulations. The method can potentially be utilized to predict trends such as filtration behaviour of materials under different states of compression. This offers significant benefits in formulating the design of flocculated systems pertinent to a number of industrial sectors wishing to design optimum solid-liquid separation processes.Read moreRead less
Drying sewage sludge using hot oil. The project seeks to investigate and develop an entirely new area of fundamental and applied research involving the process, mechanisms and kinetics of direct dehydration of sewage sludge by fry-drying in hot oil. Frying can be carried out as a drying process, though it not widely recognized or applied in this way, and has consequently not been exploited outside of the traditional food industries. It potentially provides a wide range of significant benefits ....Drying sewage sludge using hot oil. The project seeks to investigate and develop an entirely new area of fundamental and applied research involving the process, mechanisms and kinetics of direct dehydration of sewage sludge by fry-drying in hot oil. Frying can be carried out as a drying process, though it not widely recognized or applied in this way, and has consequently not been exploited outside of the traditional food industries. It potentially provides a wide range of significant benefits for sludge drying, including high efficiency and low costs, and produces a non-offensive product with a high energy value suitable for (renewable) power generation.Read moreRead less
Production of a compact disk summarising the evolution and impact of Boger fluids.

Modelling of Adsorption Dynamics in Microporous Adsorbents Using Fractional Order Diffusion Equations. This project investigates the use of fractional order diffusion equations in modelling adsorption dynamics in microporous carbons. The long tail behaviour of adsorption processes cannot be readily explained by the classical second order Fickian model, and makes adsorption a candidate for the use of fractional order diffusion equations that have the potential to model such features. In the pre ....Modelling of Adsorption Dynamics in Microporous Adsorbents Using Fractional Order Diffusion Equations. This project investigates the use of fractional order diffusion equations in modelling adsorption dynamics in microporous carbons. The long tail behaviour of adsorption processes cannot be readily explained by the classical second order Fickian model, and makes adsorption a candidate for the use of fractional order diffusion equations that have the potential to model such features. In the present project we shall develop suitable numerical techniques for solving the fractional order diffusion model, and apply these to the interpretation of experimental kinetic data. The outcome will be an improved model of adsorption dynamics considering the fractal nature of the solid.Read moreRead less

This project will develop new strategies for economically viable recovery of bioactives from complex solutions, slurries and sludges of biomaterials eg. waste streams from milk and soy bean processing, and fermentation broths. These bioactives, often proteins, have growing applications as high value drugs, nutriceuticals and food additives but are difficult to separate and to maintain in an active form. Crystallisation will be used as a primary separation technique. Molecular studies of protein interactions will be used to predict good crystallisation conditions and linked to process crystallisation studies. Both standard and novel particle design strategies will be used to control crystal size and morphology, as well as package the boactive in a deliverable form without loss of activity.Read moreRead less
