Open publisher page 0 citations

Abstract

With reference to the production features of the 130 kt/a diammonium phosphate(DAP)and the 100 kt/a monoammonium phosphate(MAP)of the Compound Fertilizer Factory of Shanxi Huashan Chemical Group Corp.,main corrosive media as phosphoric acid,fluorosilicic acid and sulfuric acid and factors which influence their corrosivity are outlined,the corrosion resistant property of the 316L stainless steel material is described,and the application of 316L from the perspective of production process of phosphoric acid and ammonium phosphate is particularly studied.
