Abstract
Volatile organic compounds including hydrocarbons, halogenated compounds and other hazardous and toxic chemicals are removed from air streams by contacting the air with a suspension of tiny water droplets sized such that the droplets have an internal pressure significantly greater than atmospheric. The solubility of organic compounds in water droplets and their rate of transfer from an air stream to the droplets increases rapidly as the droplet internal pressure rises. After substantial transfer of volatile organic compounds from the air into the droplets is accomplished, the droplets are separated from the air stream and the resulting liquid effluent is disposed of in a manner which prevents escape of contained contaminant compounds.
