  • Absorber
    Patent number: 10646819
    Abstract: An absorber is provided which uses a liquid solvent formed into a myriad of bubbles and micro-droplets. The solvent froth is a solvent for a selected component in an incoming gas stream. A plurality of spaced apart screen assemblies is placed in a reaction vessel. Using screens having cross-sections that are substantially rectangular wave in design together with proper operating parameters, the phenomenon of solvent plug pulsing is induced and maintained, maximizing efficiency of the absorber.
    Type: Grant

  • Method and means for simultaneously generating an aqueous froth and numerous micro-droplets for use in filtering a contaminated air stream
    Publication number: 20080017032
    Abstract: A method and apparatus are provided for improving the efficiency of an aqueous froth filter. An array of saturated mesh assemblies interacts with an incoming contaminated air stream. As the air stream flows through the saturated mesh assemblies, an aqueous froth is generated immediately downstream of each mesh assembly. As the bubbles of the froth move downstream towards the next saturated mesh assembly, the velocity of the air stream causes at least some of the bubbles to burst. The bursting bubbles rupture into hundreds or thousands of micro-droplets. The micro-droplets are used together with the aqueous froth to coalesce with or otherwise bind with contaminants in the air stream. An optional feature is that massive particles greater than three microns in diameter are removed by inertial impaction, whereby those heavy particles collide with the walls of serpentine shaped vanes of a mist eliminator. The method and apparatus are capable of filtering chemical and biological warfare agents out of an air stream.
