Abstract

Abstract A pollution control system including a smokestack placed at a substantially elevated location on adjacent mountainous terrain and a tunnel interconnecting the smokestack with a source of airborne pollutants. A water-operated scrubber is placed in a part of the tunnel to remove some of the pollutants from the gaseous effluent stream. A heater and a blower increase the upward velocity of the residual effluent stream to assist in impelling it out of the top of the smokestack for dispersal into the atmosphere.
