Abstract
Phosphoric acid is a major raw material for the production of ammonium phosphate (AP) that is used as an intermediate in fertilizer production. Impurities within commercial grade wet process phosphoric acid are important in producing a fertilizer granule with good handling properties. The impurities identified as being important are; iron (III), aluminium and fluorine-containing compounds. Results show that the viscosity of the AP slurry produced increases by increasing the amount of impurity in the acid. Bench scale tests have been successfully replicated on a plant scale leading to a better understanding of the composition of impurity levels within phosphoric acid required to produce a high quality, free flowing, hard, spherical and non-caking granular fertilizer.
