Détails du produit

Les anneaux Raschig en métal sont les premiers emballages aléatoires développés. Ils ont une forme simple, avec une hauteur égale à leur diamètre. Ils ont une excellente résistance aux acides, étant capables de résister à la corrosion de tous les acides sauf l'acide fluorhydrique (HF), et ils sont également résistants aux températures élevées et au vieillissement. Ils sont faits de tôles, avec une hauteur égale à leur diamètre. Les tailles couramment utilisées vont de 25 mm à 75 mm (avec des plus petits aussi petits que 6 mm et des plus grands jusqu'à 150 mm). L'épaisseur des anneaux métalliques est de 0,8 mm à 1,6 mm. Sous réserve que la résistance soit autorisée, l'épaisseur de la paroi des anneaux doit être aussi mince que possible. Bien que les anneaux Raschig aient des performances de transfert de masse moins qu'idéales, ils sont toujours adoptés par certaines usines en raison de leur structure simple, de leur fabrication facile et de leur faible coût.
