Abstract

Control and recovery of phosphorous pentoxide emission as phosphoric acid in a zinc phosphide production plant was carried out. The control unit has been designed and fabricated on a semi-pilot scale The results obtained showed that the water and air flow rates are important factors which affect the percentage recovery of P2O5 from the flue gases. Also, mist elimination is an important step in the pollution control efficiency. The obtained results revealed that recirculation of phosphoric acid are very efficient in the absorption of P2O5. Detailed engineering design and cost estimation for a full scale system were carried out. The project was successfully implemented in Nasr Company for Intermediate Chemicals at Giza Governorate, Egypt.
