Acid wet scrubbing ammonia method
Wet scrubbing ammonia method of sulfuric acid (H2SO4), nitric acid (HNO3(H), phosphoric acid3PO4) or ammonium sulfate ((NH4)2SO4) measurement
When need to deal with emissions of ammonia, wet scrubbing technology can be adopted.
In the pickling process, washing liquid will join acid react with ammonia to produce ammonium salt, ammonium salt can be safely released into the sewer or wastewater treatment plants, can also be sold as a liquid or solid fertilizer.
In a continuous gas liquid absorption system, the concentration of a solution of recycling will always controlled, to ensure the washing liquid in a proper acidity (usually a pH value of 3 and 6), and through timely fill acid to keep washing ability.The acid and the amount of water will be based on the pH and the concentration of detergents and under control.
Visa K - PATENTS®On-line refractometer to continuous monitoring the concentration of washing the bottom products.After configuration, the reading of the refractometer can display the preferred control unit, such as total solids (TDS) or density.
In situ refractometer can be used to:
- Control fresh acid added.This will ensure that to achieve the ideal of ammonia absorption conditions.
- By controlling the inlet valve and the acid valve, concentration of acid will be diluted to the target.
