Abstract
A method and system are described to remove solvent vapors emanating from a source in a work place. The air stream is passed through a fogging chamber in which a plurality of ultrasonic foggers are used to create a supersaturated condition in the form of vapor and droplets of a scrubbing liquid such as water. The supersaturated condition is accompanied with a large amount of turbulence and mixing flows throughout the chamber to reduce the ability of solvent vapors from bypassing contact with the scrubbing liquid. The scrubbing liquid droplets and vapor are then condensed out in a cooling condenser and collected to leave a scrubbed air stream from which a substantial amount of the solvent vapors is removed. The scrubbed cooled air stream may then be recirculated for reuse in the work place. Several embodiments are shown and described including a scrubbing system in which several fogging chambers and condensers are used in tandem for an enhanced removal of solvent vapor from the air stream.
