Ammonia Scrubber

The scrubbing of ammonia from the air stream can be successfully done with the use of a wet scrubber. A correctly designed scrubbing tower can offer removal efficiencies of +99%.

Q-Pac packing is used to provide a plug resistant and low pressure drop option to this problem.

Design Example:
Ammonia is release into the air from process. The fugitive fume is capturing a transported to a scrubber column. Ammonia is a known irritant and requires removal from the workplace before it gets into the workers respiratory system.

Design considerations are as follows:-

Air flow:
Peak Inlet Concentration:
Scrubbing Efficiency:

16,300 Nm³/hr
95 ppm_v
>1 ppm_v

Recommendations:-

Tower diameter:
Superficial Gas Velocity:
Packing:
Packed Depth:
Scrubbing Liquor:
Recirculation Rate:
Liquid flux:
Q-PAC Pressure Drop:
