| Abstract: | The influencing factors for total nutrient of slurry process monoammonium phosphate (MAP) are analyzed, that mainly include impurity levelin the phosphofite, solid content in dilute phosphoric acid, and (?)(SO42-)free. The measures for adjusting the total nutrient are described, includingclarifying the dilute phosphoric acid and reducing its solid content to increase the total nutrient of the product ; adding chalk powder, sulphuric acid, phos-phate gypsum, and using compounding slurry and slag to reduce th... |
