Air Pollution Control Systems for Ammonia Scrubbing & Ammonium Sulphate Manufacture - Chemical & Pharmaceuticals

For processes generating significant quantities of ammonia in the vent gas, ERG has experience scrubbing this into dilute sulphuric acid solution to make >25% ammonium sulphate solution suitable for sale as fertiliser. Using the V-tex® scrubber which operates efficiently with viscous and high density scrubbing solutions, the liquid effluent stream can be controlled to a high concentration of (NH4)2SO4, minimising the water content and maximising the revenue stream from this liquid effluent. The solution can be further concentrated using an evaporator if required.
