R\u00e9g\u00e9n\u00e9ration du tamis mol\u00e9culaire\/z\u00e9olite 5A PSA<\/h3>\n

Les tamis mol\u00e9culaires de type 5A PSA peuvent \u00eatre r\u00e9g\u00e9n\u00e9r\u00e9s soit par chauffage dans le cas des proc\u00e9d\u00e9s \u00e0 oscillation thermique, soit par abaissement de la pression dans le cas des proc\u00e9d\u00e9s \u00e0 oscillation de pression.<\/p>\n

Pour \u00e9liminer l'humidit\u00e9 d'un tamis mol\u00e9culaire 5A, une temp\u00e9rature de 250-300\u00b0C est n\u00e9cessaire. Un tamis mol\u00e9culaire correctement r\u00e9g\u00e9n\u00e9r\u00e9 peut donner des points de ros\u00e9e inf\u00e9rieurs \u00e0 -100\u00b0C, ou des niveaux de mercaptan ou de CO2 inf\u00e9rieurs \u00e0 2 ppmv.<\/p>\n

Les concentrations \u00e0 la sortie d'un proc\u00e9d\u00e9 \u00e0 oscillation de pression d\u00e9pendent du gaz pr\u00e9sent et des conditions du proc\u00e9d\u00e9.<\/p>\n

Application du tamis mol\u00e9culaire\/z\u00e9olite 5A PSA<\/h3>\n

Il est utilis\u00e9 pour la purification des hydrocarbures GPL, le d\u00e9paraffinage du p\u00e9trole, la production d'hydrog\u00e8ne PSA, la d\u00e9shydratation et la purification.<\/p>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"

Le tamis mol\u00e9culaire 5A est un silicate alcalin alcalin ; il s'agit de la forme calcique de la structure cristalline de type A. Le type 5A a une ouverture de pore effective de 5 angstr\u00f6ms (0,5 nm). Le type 5A a une ouverture de pore effective de 5 angstr\u00f6ms (0,5 nm). Il adsorbe les mol\u00e9cules dont le diam\u00e8tre cin\u00e9tique est inf\u00e9rieur \u00e0 5 angstr\u00f6ms et exclut celles qui sont plus grandes.<\/p>\n

5A Molecular Sieve is an alkali alumino silicate; it is the calcium form of the Type A crystal structure. Type 5A has an effective pore opening of \u00a05 angstroms (0.5 nm). It will adsorb molecules with a kinetic diameter of less than 5 Angstrom and exclude those larger.<\/p>\n

It is especially suitable for PSA adsorber applications where it may be used for the separation of normal- and iso- paraffins (C4 to C6 species), in PSA hydrogen purification and in oxygen concentrators.<\/p>\n","category_list":"","author_info":{"name":"","url":""},"comments_num":"0 commentaire","_links":{"self":[{"href":"https:\/\/www.laiko.net\/fr\/wp-json\/wp\/v2\/product\/3455","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.laiko.net\/fr\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.laiko.net\/fr\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.laiko.net\/fr\/wp-json\/wp\/v2\/media\/1009"}],"wp:attachment":[{"href":"https:\/\/www.laiko.net\/fr\/wp-json\/wp\/v2\/media?parent=3455"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.laiko.net\/fr\/wp-json\/wp\/v2\/product_cat?post=3455"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.laiko.net\/fr\/wp-json\/wp\/v2\/product_tag?post=3455"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
