  • New fertilizer industry gas cleaning technology achieves lower required emission levels

    All fertilizer plants produce dust and gases, such as ammonia (NH3) and acid fumes, which must be removed at very high efficiencies before venting to atmosphere. Familiar examples are granulation and prilling of nitrogenous products such as Urea which is the most widely used fertilizer in the world(1). Phosphatic fertilizer production produces dust and Fluorine compounds. Typical air treatment ...
