Popis: Palladium and palladium/alloy membranes have shown to be an effective technology option for the production of pure hydrogen. In particular, Pd/Au membranes have displayed superior chemical stability and separation performance. However, the lack of industrial operating experience gives rise to technological uncertainties such as the lifetime of the membranes which could potentially prevent the deployment of this new technology option. In light of the above recognition, the primary aim of the present research work is to combine long-term H2 membrane permeance and He leak characterization tests (cumulative testing over 2.2 years) conducted to estimate the lifetime of composite asymmetric Pd/Au membranes at different thicknesses with a comprehensive economic performance assessment framework in the presence of inherent trade-offs between permeance, thickness, and membrane lifetime. The experimental results are depicted in terms of the produced H2 purity and flux at different testing times and various membrane ...
