Scrubbing liquid is distributed over a weir or shelf - … We specialize in the treatment of particulate and gaseous emissions from industrial sources. Industrial scrubbers are pollution control devices that use liquid to wash unwanted pollutants from a gas stream, or that inject a dry reagent or slurry into a dirty exhaust stream to "wash out" acid gases. Our systems include wet electrostatic precipitators, high efficiency Venturi scrubbers, and packed bed absorbers. Because of this, it’s critical for companies to know that one of the most effective tools against rising carbon emissions and the acidic chemicals being released into the atmosphere has been the use of wet scrubbers. Houston, Texas 77090 This transfer requires both the humidification of the gas by the host liquid and creation of target droplets into which the transference occurs. A type of Wet Scrubber, the Venturi Scrubber uses Venturi technology, which has been used for over 100 years. AIR POLLUTION CONTROL APPLICATIONS This feature also permits adjustment of pressure drop to upgrade collection efficiency to meet increased process or code requirements.
