<p>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 aqueous droplets sized such that the droplets have an internal pressure significantly greater than atmospheric. The capacity of aqueous droplets to hold organic compounds and the rate of transfer of organic compounds from an air stream to the droplets increase rapidly as the droplet size decreases and the droplet internal pressure rises. After substantial transfer of volatile organic compounds from the air into the droplets is accomplished, the droplets are caused to grow and to coalesce and are separated from the air stream. The resulting liquid effluent is disposed of in a manner which prevents escape of contained contaminant compounds.</p> |
