This paper describes the design and process of fabricating planar membranes for oxygen separation. The fabricated membranes are assembled in a module with a 4-end mode configuration, where the oxygen-rich feed-gas is fed from one side of the component, while the permeated oxygen is removed through the feeding of an oxygen-poor gas from the other side.<\/p>\n","protected":false},"author":93,"featured_media":0,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false,"footnotes":""},"tags":[1305,1300,1395],"targets":[1304,1317],"pubblicazioni_tipologie":[772],"class_list":["post-194417","pubblicazioni","type-pubblicazioni","status-publish","hentry","tag-energy-efficiency-en","tag-industrial-sector","tag-membranes","targets-industrial-world","targets-research","pubblicazioni_tipologie-article-en"],"acf":{"order_posts":"","dont_show_search":false,"related_posts":false,"dont_show_hompage":false,"show_on_slider":false,"single_post_data":{"titolo_spot":"","post_content":"
Membrane separation-based oxy-combustion is a promising technology for efficient combustion of coal-containing fuels due to the opportunity to simultaneously capture CO2<\/sub>from the resulting flue gases. The conditions of oxygen combustion require a special design of ceramic membranes because of the high pressure and high temperatures applied. Therefore, a planar membrane module was designed with a 4-end mode configuration using asymmetrical membranes La0.6<\/sub>Sr0.4<\/sub>Co0.2<\/sub>Fe0.8<\/sub>O3-<\/sub>\u03b4<\/sub>. FEM and CFD simulations were performed to develop the internal channel structure of the membranes, which can withstand a pressure of 5 bar applied on the feed side, while achieving 27% O2<\/sub>concentration in the sweep gas, such as CO2<\/sub>, and an 86% oxygen recovery from the feed gas.<\/p>\n Membrane components have a symmetrical design which makes them easily scalable. The membranes were fabricated by optimising a chain process from powders to the final component; the latter is made up of a dense membrane layer 20 \u03bcm thick, a substrate with 38% porosity, an internal channel structure and a thin active porous layer (3-5 \u03bcm). Special emphasis was placed on the scalability of the fabrication process so as to ensure that it can also be realised on an industrial scale. The chain process is also applicable to other materials for any application of interest. Finally, the reproducibility of the process was successfully demonstrated by fabricating membrane components 100 mm long and 70 mm wide.<\/p>\n","scarica_file":false,"link_estreno":[{"link_text":"Download Article","link":"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S138358661833404X"}],"button":{"text":"","link":""},"referente_group":false,"data_emissione":"2019-03-19","autori":"F.
