Ammonia Scrubber
Ammonia Scrubber introduction：
However, ammonia is also formed in nature in smaller quantities. Most of the ammonia (90%) is utilized for fertilizer production but ammonia can be found in food, pharmaceutical products, and cleaning supplies. When ammonia gas is released to the air it has a very noxious and pungent odor that can be dangerous to inhale so often times odor control scrubbers are required to capture and treat the ammonia gas.
How to deal with ammonia gas
Sulfuric acid solutions are used to neutralize ammonia in gas streams, while caustic can be used to adjust the pH of waste streams prior to disposal. Ammonia pollution gas enters from the bottom of the vertical packed tower, and the air flows upward. The aqueous solution containing sulfuric acid (H2SO4) is recycled during the cycle. Chemicals are introduced at the top of the vertical column through a designed distribution system and down through the media bed. Random fill media are typically made of polypropylene material and are resistant to low pH solutions. The media bed is supported by a false bottom separating the media bed from the solution tank below. The air then moves upward, encounters an acidic solution, and reacts to neutralize the ammonia gas.
Achieving high removal efficiencies is critical, and with ammonia scrubbers, removal rates of 99% and above can be achieved with full control and automation. Odor control scrubbers and chemical scrubbers use acids, caustic and other reagents and are designed for harsh environments to handle toxic gases.
What is ammonia gas?
Ammonia (NH3) is a colorless, corrosive, irritating gas used in a variety of industries including pharmaceuticals, fertilizers, food, chemicals, and semiconductors. It has an explosive range of 16% to 25% by volume in air and is moderately toxic. It has an Immediately Life and Health (IDLH) Concentration of 300 ppmv and an OSHA Permissible Exposure Limit (PEL) of 50 ppmv. Ammonia has an odor threshold of 5 ppmv, which is a sufficient olfactory warning of potential danger. Although ammonia is not a Hazardous Air Pollutant (HAP), it is regulated as a precursor of PM2.5 and PM10 standard air pollutants. This is because it reacts with acid gas pollutants to form the corresponding ammonium salts in the atmosphere.
Product structure of ammonia adsorption scrubber
The ammonia scrubber has a simple structure, a vertical structure, and a small footprint. It is composed of bottom water tank, middle filling absorption section, spray section and top exhaust section. There are 4 inlet and outlet pipes, which are ammonia gas inlet, exhaust outlet, spray water inlet and liquid outlet.
