| titleOfInvention | Method of processing calcium phosphate to phosphoric acid and lime or cement |
| abstract | FIELD: industry of mineral fertilizers. SUBSTANCE: method involves mixing phosphoric acid phosphate suspension with sulfuric acid during blowing suspension with run-off flue gas followed by settling, filtration or centrifugation of condensed phosphoric acid sulfate suspension, heating with flue gas, mixing calcium sulfate with methane at molar ratio methane sulfate 1:4, not above, obtaining the lime and concentrated sulfur dioxide gas which is processed to sulfuric acid recovered to the process. EFFECT: simplified process, decreased energy and labor input, decreased exhausts in atmosphere. 4 cl, 3 dwg |
