| Abstract: | Sulfur based NPK is a kind of high nutrition compound fertilizer with low nitrogen content developed by our country.It can be widely applied and its production cost is low.Through revamping the ammonium phosphate plant,it can be produced,but the nitrogen content in the product is rather low.In the article,the reason of the lower nitrogen content is analyzed,the measure has been used in 200 kt/a S-NPK plant,nitrogen content in the product has been increased from 12% to 14%,the specification requirement of 15-15-15 has been basically reached. |
