A process for the extraction of an unwanted material from a gas comprising
the steps of introducing an extraction liquid into a fluid having an
unwanted liquid therein to form a physical aerosol comprising a plurality
of extraction liquid droplets and the fluid, allowing the plurality of
extraction liquid droplets to interact with the unwanted liquid in the
gas to cause the extraction liquid droplets to be "wetted out" and
captured on a porous medium, where the liquid is further contacted by the
gas and simultaneously formed into a plurality of coalesceable droplets,
coalescing the coalesceable droplets into larger droplets containing the
unwanted liquid, and separating the larger droplets containing the
unwanted liquid from the fluid.
