How much does a 300000 tons capacity triple super phosphate factory require water?

Answer 1

Triple super manufacture needs phosphoric acid of approximately 40% concentration of P2O5. If TSP contais say 46% P2O5, 25-27% of P2O5 is dervied from Phosphate rock and 73% through phosphoric acid. This means on 100% P2O5 basis, about 330 kg of P2O5 is required through phos.acid. In terms of 40% acid, it is 825 kg of 40% acid. Normally, merchant grade acid is of 52-54% P2O5 concentration. Therefore, you need to dilute phosphoric acid of 54% to 40%. this is 825-611=214 kg/ton of TSP. Generally tihs water of dilution is obtained through recycling scrubber water. When the fresh TSP from the den is granulated, you do not require much water. Considering other process requirements and losses, you may need about 500 kg of water per ton of TSP. Visweswara Rao.
