EXTRACTION PHOSPHORIC ACID TRANSPORTATION METHOD Russian patent published in 2002 - IPC

Abstract RU 2194668 C1

FIELD: inorganic compounds technology. SUBSTANCE: extraction phosphoric acid is prepared simultaneously with phosphoric acid-based fertilizers. Overall process consists in production of phosphoric acid, transportation thereof, and production of fertilizers. Stabilization of phosphoric acid comprises adding to phosphoric acid precipitation-preventing agent, in particular gaseous ammonia in amounts required to achieve NH3/H3PO4 molar ratio (0.3-0.5): 1, which completely eliminates formation of incrusting precipitates. EFFECT: reduced total amount of precipitates. 1 tbl
