DEFINITION

Classification: 96/290

Particulate media, shaped packing elements (e.g., Raschig rings, Berl saddles, etc.), or porous media for gas and liquid contact:

(under subclass 243) Apparatus having means to apply the contact liquid to a contact means comprised of (a) a plurality of small, discrete solids permitting flow of the gaseous fluid mixture or the separated gaseous constituent through interstices formed between the solids (e.g., particulate bed, etc.), (b) a mass of randomly oriented or positioned elements which may be molded, machined, or formed, that possess specific advantages of surface availability for contacting the contact liquid and the gaseous fluid mixture or the separated gaseous constituent (e.g., Raschig rings, Berl saddles, Intalox saddles, Pall rings, etc.), or (c) a mass having pores therein providing interstices and thereby surface extending paths therein for liquid contact with the gaseous fluid mixture or the separated gaseous constituent passing therethrough.
