The project seeks to develop gas separation membranes displaying superfluxes - throughputs 10 to 100 times higher than current systems, with lower operating costs. There is compelling evidence that very high flow rates are achievable and they have been shown for single gas transport. Theory predicts that highly selective separations are possible, but this has not yet been experimentally shown - a key outcome from this project. The applications are widespread and include separation of carbon dioxide from power station flue gas for sequestration, purification of natural gas and provision of pure component gases such as oxygen and nitrogen amongst others.Read moreRead less

System geometry greatly influences flow hydrodynamics and hence the transport of colloidal particles and ionic species from the bulk to the surfaces that result in formation of unwanted deposit matter on the surface. The formation of unwanted deposits has significant environmental and economic penalties. This project uses a new approach that is combining the CFD modelling and experimentation including flow visualization by PIV to systematically investigate the effect of channel geometry and flow on deposit formation. The outcomes of the project will result in a better understanding and formulating of the effect of geometry on deposition of colloidal particles and ionic species on the surfaces. The results contribute not only towards the mitigation processes for unwanted deposition; it also advances the knowledge in coating applications.Read moreRead less
