This report describes the research activities regarding the development of membrane technologies for oxygen separation to be integrated into production processes, with the aim of reducing energy consumption in the industrial sector where they are applied.<\/p>\n
Comparative studies of the integration of membrane modules in an industrial process were conducted to identify a range of operating conditions, in terms of temperature, pressure, and gas composition, to which the materials may be exposed during operation. These conditions are used as a reference for the subsequent characterization of samples and for the design of the membrane module.<\/p>\n
The experimental activity focused on optimizing the procedure for fabricating membrane samples. An appropriate choice of binder particle size allowed for the production of dense, defect-free samples, as confirmed by microstructural characterization and ambient temperature tests in helium. Microstructural observations of the section revealed the desired asymmetric structure, with a membrane layer thickness of 15-20 \u03bcm and support porosity around 32%. Additionally, successful deposition tests of large samples (85 x 45 mm) were conducted, and the thermal treatment process for debinding and sintering was optimized, yielding defect-free samples with an asymmetric structure. The first lamination tests for the assembly of the membrane component were also initiated, with encouraging results.<\/p>\n
To estimate the probability of material fracture, mechanical characterization was performed through four-point bending tests on a large number of specimens (over 30) taken from two different samples. The test results were analyzed using a statistical method to estimate the mechanical properties at room temperature. The initial results allowed for a preliminary assessment of a simple membrane component model to verify its resistance to stress under operating conditions. The study on a 100×100 mm component with channels for sweep gas supply showed that, at room temperature and with a pressure difference of 4 bar between the outside and inside of the component, the probability of failure is less than 10^-7. In a subsequent phase of the activity, the performance of the produced material will also be evaluated at operating temperature.<\/p>\n","link_estreno":false,"scarica_file":[{"download_option":"download","file_name":"Download Report","download":{"ID":105766,"id":105766,"title":"19012854-319114.pdf","filename":"19012854-319114.pdf","filesize":3849703,"url":"https:\/\/www.rse-web.it\/wp-content\/uploads\/2021\/03\/19012854-319114.pdf","link":"https:\/\/www.rse-web.it\/en\/rapporti\/19012854\/19012854-319114\/","alt":"","author":"464","description":"19012854-319114.pdf","caption":"","name":"19012854-319114","status":"inherit","uploaded_to":132842,"date":"2021-12-31 00:00:00","modified":"2021-03-17 12:49:57","menu_order":0,"mime_type":"application\/pdf","type":"application","subtype":"pdf","icon":"https:\/\/www.rse-web.it\/wp-includes\/images\/media\/document.png"}}],"button":{"text":"","link":""},"referente_group":false,"data_emissione":"2019-12-31","autori":"A.
