| titleOfInvention | Process for the manufacture of phosphoric acid |
| abstract | PROCESS FOR PRODUCING PHOSPHORIC ACID BY THE ACIDULATION OF PHOSPHATE ROCK WHEREIN SUBSTANTIALLY ALL THE REQUIRED ACID IS REGENERATED WITHIN THE PROCESS. THE PREFERRED PROCESS COMPRISES THE STEPS OF TREATING BY-PRODUCT CALCIUM SULPHATE, IN THE FORM OF GYPSUM, WITH AMMONIUM CARBONATE TO PRODUCE AMMONIUM SULPHATE AND CALCIUM CARBONATE, THEREAFTER REACTING THE THUS PRODUCED AMMONIUM SULPHATE WITH FLUOSILICIC ACID TO PRODUCE AMMONIUM FLUOSILICATE CRYSTALS AND SULPHURIC ACID. THE FLUOSILICIC ACID IS REGENERATED BY REACTING THE RESULTING AMMONIUM FLUOSILICATE WITH AMMONIUM BISULPHATE, TO PRODUCE FLUORSILICIC ACID AND AMMONIUM SULPHATE. THE AMMONIUM SULPHATE IS HEATED TO DRIVE OFF AMMONIUM AND REGENERATE AMMONIUM BISULPHATE. |
