Diesel Exhaust Scrubber

Product Description:

Working:

Packed bed scrubber enlarges the space between the fluid and the gas that is exhausted. This helps in purifying the exhaust gas with its internal special pieces. Special hollow thermoplastics are used in packing which helps in removing soluble gases like HCl, Cl, BR2, NH2, SO2, H2S, & Nox.

Scrubber efficiency usually depends on the interfacial area between the liquid, gas and the turbulence at the interface. Gas, liquid flows and the required concentration change are the most important design parameters that are considered while designing   the scrubber column.

Other Technical Details

vertical bedVertical Packed Bed Scrubbers provide one of the most efficient removals of acid gases, odors and vapor fumes by using a vertical counter flow design.  The contaminated gas flows up while recirculating liquid sprays downward into the packed bed.  The gases are absorbed by the scrubber solution solubility level and by chemical reaction.

Vertical Packed Bed Scrubbers are commonly used in application removals of odors such as Amines, Ammonia, Diamines, H2S, Mercaptans, Organic Sulfides and Skatole.

The vertical counter-flow design typically provides the best scrubbing efficiency of vapors and is the most common design found in most industries. Vertical Packed Tower Scrubber is normally not used when solid particulate is in the air stream. Air flow capacity for a single shop fabricated tower can be up to 75,000 CFM.

horizontalThis is a cross-flow design with scrubbing liquid flowing vertically downwards while the gas passes horizontally through the packing section. Horizontal Packed Bed Scrubber is used when limited headroom is an issue at a customer’s facility or when low profile is desired for roof-top applications. Multiple stages can be easily provided in one housing with separate sumps and pumps if required.

The cross-flow design is less susceptible to fouling for airstreams that may contain solid particulate. Air flow capacity for a single shop fabricated tower can be up to 75,000 CFM.
