Acid Wet Scrubbing of Ammonia


Ammonia is widely used in a variety of industries. Emissions of ammonia are of great concern as they contribute to several environmental problems including eutrophication and contamination of groundwater. Wet scrubbing is used successfully to control ammonia emissions, achieving efficiencies up to 99 %. However, wet scrubbers create effluents that need to be treated and disposed.

Vaisala K-PATENTS® Teflon Body Refractometer PR-23-M monitors continuously the concentration of the bottom product of the scrubber. The reading from the refractometer can be configured to show the preferred control unit, for example, Total Dissolved Solids (TDS) or density.
