Air pollution control equipment manufacturers are continually developing sophisticated systems designed to dramatically reduce plant emissions. One such system, the ionizing wet scrubber (IWS), has demonstrated outstanding air pollution control characteristics while meeting the challenge of energy efficiency. The IWS system removes fine solid and liquid particulate down to 0.05 micron at high collection efficiencies and low energy comsumption. It also simultaneously removes noxious, corrosive and odor-bearing gases from flue gas streams as well as coarse particulate matter above 1 micron in diameter. Due to its simplified design and low pressure drop, operating energy costs of the IWS are only a fraction of those for alternative air pollution control equipment. Pressure drop through a single-stage IWS is only 0.5 to 1.5 in. Water (125 to 374 pa) column and is controlled primarily by pressure drop through the wet scrubber section. Total system energy usage is approximately 2.0-2.5 bhp/1,000 actual ft/sup 3//min (0.7-0.9 kw/m/sup 3//min) for a single-stage IWS and 4.0-5.0 bhp/1,000 actual ft/sup 3//min for a two-stage installation. These energy requirements represent a significant savings as opposed to other air pollution control systems such as Venturi scrubbers.
