Title (EN) CHILL-PROOFING COMPOSITE FILTER AIR AND RELATED METHODS
(FR) MOYEN AUXILIAIRE DE FILTRATION COMPOSITE DE RÉSISTANCE AU FROID ET PROCÉDÉS ASSOCIÉS
Abstract:
(EN) A chill-proofing composite filter aid may include a filtration component and an adsorption component including precipitated silica at least partially coating the filtration component. The composite filter aid may have a pore volume of at least about 0.15 cm3/gram at an average pore size between 3 nanometers and 15 nanometers. A method for removing particles from a fluid may include providing a chill-proofing composite filter aid, pre-coating a filter element with the composite filter aid, and passing a fluid containing particles to be adsorbed through the coated filter element, A method of making a chill-proofing composite filter aid may include providing a filtration component, and at least partially coating the filtration component with an adsorption component including precipitated silica. The composite filter aid may have a pore volume of at least about 0.15 cm3/gram at an average pore size between 3 nanometers and 15 nanometers.
(FR) L'invention concerne un moyen auxiliaire de filtration composite de résistance au froid pouvant comprendre un élément de filtration et un élément d'adsorption comprenant de la silice précipitée revêtant au moins partiellement l'élément de filtration. Le moyen auxiliaire de filtration composite peut présenter un volume de pore d'au moins environ 0,15 cm3/gramme pour une taille de pore moyenne comprise entre 3 nanomètres et 15 nanomètres. Un procédé d'élimination de particules d'un fluide peut comprendre la fourniture d'un moyen auxiliaire de filtration composite de résistance au froid, le revêtement préalable d'un élément filtrant avec le moyen auxiliaire de filtration composite et le passage d'un fluide contenant des particules devant être adsorbées à travers l'élément filtrant revêtu. Un procédé de fabrication d'un moyen auxiliaire de filtration composite de résistance au froid peut comprendre la fourniture d'un élément de filtration, et le revêtement au moins partiel de l'élément filtrant avec un élément d'adsorption comprenant de la silice précipitée. Le moyen auxiliaire de filtration composite peut présenter un volume de pore d'au moins environ 0,15 cm3/gramme pour une taille de pore moyenne comprise entre 3 nanomètres et 15 nanomètres.
