The “phosphorus reduction and acid concentration improvement” technology in phosphate production
Thread Content
I would like to ask my fellow Sichuanese friends: does anyone know what the technique of \"reducing phosphorus content and increasing acid concentration\" in phosphate production refers to?
Could it be phosphoric acid falling-film concentration? I’m not sure if that’s correct
It can’t be lowering the phosphate content to increase the hydrogen ion concentration, right? Are there any other indicator requirements? If no specific requirement is given, just add some sulfuric acid and that’s fine
In fact, phosphorus reduction and concentration involves sacrificing the phosphorus yield during the reaction process in order to increase the phosphate concentration. There is a prerequisite for this: as the phosphate concentration rises, the energy consumption (for steam and electricity) during the concentration process decreases. The key lies in determining how to achieve a balance – which approach is more economical – and this requires evaluation.
In phosphate production, the phosphate concentration is expressed in terms of P2O5. I’m not sure how phosphorus reduction and concentration enhancement can be achieved
If the acid concentration has nothing to do with phosphoric acid, then the water in dilute phosphoric acid can be evaporated; however, this doesn’t correspond to reality, as it would increase production costs
