Wet Scrubbers / Vertical Flow Packed Bed

Packed Bed Scrubbers are used to remove inorganic gases, odors, fumes and gas streams that contain high pH levels. They are effective for odor removal such as Hydrogen Sulfide, Ammonia, Acetic Acid, Ketones, Amines and Chlorine just to name a few. Packed Bed Scrubbers utilize high mass transfer and liquid recycle rates in order to guarantee adequate chemical is available to absorb odors.

Ecologix' packed bed scrubbers are versatile, reliable systems that serve the widest variety of processes. They are used and specified worldwide. Ecologix packed scrubbers are highly recommended for the efficient removal of inorganic gases, odors and fumes, and are particularly appropriate where gas streams have extreme pH. They are well-suited for use as primary or secondary systems in conjunction with thermal oxidizers, and are also used in a series where there are multiple-contaminant. Optimum system performance is achieved with systems that combine intimate gas/liquid mixing and low pressure drop.

There are four broad categories of information which influence the design of these systems.

CFM
Air flow through the scrubber, based on cubic and mist eliminator requirement in microns. ft/min. This is determined by the process to be provided by customer and Ecologix analysis. System capacities of heavy service V/F systems range to 100,000 cfm and above.

Configuration
Internal vs. external recirculation system, fan location in relation to tower, duct sizes, inlet and outlet plus location of pump systems, tower access service ports, service platform requirement.

Materials of Construction
Determined by application; because most contaminants involve corrosive gases and fumes, material must be able to withstand continuous contact with high and low pH gases and scrubbing solutions.

Operational Efficiency
Removal efficiency of scrubber: inlet vs. outlet requirement, based on mass emission in lbs/hr. in vs. lbs/hr. out.

Producing a Practical System Design
Using the information gathered under the efficiency requirement section above, and other factors specific to the site, Ecologix engineers determine the optimum tower diameter, packing depth, recirculation flow rate, and mist eliminator requirement in microns.
