Abstract
The influence of impurities in phosphoric acid on the granulometery of the produced DAP was experimentally investigated in a petrochemical plant. It was found that DAP granulometery can be substantially improved as the total concentration of aluminum and iron oxides in the phosphoric acid is increased up to 2.2±0.1 wt%. A correlation was proposed for predicting the DAP granulometery in terms of total concentrations percent of (Al2O3+Fe2O3) in the phosphoric acid.
