Packed Tower Scrubbers, Type W70

The Emtrol Model W70 Packed Tower Scrubber is utilized to absorb gaseous compounds, acid mists and odors through the counter-current flow of gases and scrubbing liquid over a packed section.  This unit is meant to operate at a very low pressure drop, thereby reducing power consumption and energy costs.  The design and location of internal parts eliminates gas channeling and assures trouble-free operation as there are no moving parts.  The W70 is easily adapted to new or retrofit applications and no support structure is required.

 

Gases enter the Packed Tower through a wide inlet area providing an even distribution of gases throughout the tower.  Even distribution of the gases flowing counter-current with the scrubbing liquid increases contact time with the packing material, assuring the proper chemical reaction/absorption time needed to effectively remove contaminants from the gas stream.

Immediately following the packed section is a mist eliminator for removal of any free water droplets. The Packed Tower spray headers assure distribution of liquid over the packing material and periodic wash down of the mist eliminator, which are elements necessary for effective operation.

Emtrol Packed Towers are constructed of F.R.P. (fiber reinforced plastic) material with a corrosion resistant inner surface.

For ease of retrofitting, both vertical and horizontal outlet styles are available and inclusive to the design are lifting and hold down lugs, access doors, and internal supports for packing grids and mist eliminators.

The benefits of a Packed Tower Scrubber are:

choice of outlet style -- vertical or horizontal

units are complete with lifting & hold down lugs & access doors

internal supports for packing grids & mist eliminators are inclusive to the design

low pressure drop reduces energy costs

Many air pollution control firms sell similar units; however, Emtrol's expertise in scrubbing technology, corrosion resistant materials and system design is proven to provide the optimum performance in challenging applications.
