Scroiler™ produces the cleaning mist differently from other scrubber systems, which results in running costs that are much lower than for a common wet scrubber. The gas flows through a second scrubber, a packed bed absorber, where the rest of the gases (and particulate matter) are collected. Scrubbing liquid is evenly introduced through a liquid distributor located above the packing and flows down through the plastic scrubber packing. Other solvents such as hydrocarbon oils are used for VOC that have low water solubilities, though only in industries where large volumes of these oils are available (e.g., petroleum refineries and petrochemical plants). Envitech's high-efficiency, low pressure drop packed bed scrubbers use random or structured packing, a mist eliminator, and a liquid distribution system to remove acid and toxic gases through a process of absorption and neutralization. The gas flows through a second scrubber, a packed bed absorber, where the rest of the gases (and particulate matter) are collected. Figure 5-5. Pollutant removal may be enhanced by manipulating the chemistry of the absorbing solution so that it reacts with the pollutant. These scrubbers typically combine spray and packed bed sections followed by a mist eliminator in a horizontal vessel for maximum separation of soluble gases, particulate matter, and mist particles. The VOC must be soluble in the absorbing liquid and even then, for any given absorbent liquid, only VOC that are soluble can be removed. Exhaust gas enters the scrubber where it contacts the scrubbing fluid. Packed-bed scrubbers provide excellent gas-liquid contact and efficient mass transfer; they can generally be smaller in size than spray scrubbers and so are an effective option when space is limited. The so-called packed bed, that is often used in air scrubbers, is a hollow tube or pipe filled with a specifically designed packing material.
