Abstract
A fiber bed element and process for utilizing such element for removing and collecting small particles of liquids or soluble solids from a gas stream, the element formed of one or more layers of pin-punched fiber supported by an appropriate supporting structure, the fiber layers being subjected to pressure to achieve a selected density and the punched holes functioning to create drainage paths through which liquids may drain. The fiber layer density and fiber size is maintained uniform throughout the element so that the pressure drop of the saturated filter bed element will be between 1.1 and 3.0 times the pressure drop of the dry filter bed as originally constructed and before use.
