| titleOfInvention | PROCESS FOR THE PREPARATION OF POTASSIUM SULFATE FOR USE IN PARTICULAR IN FERTILIZERS FROM BRINES CONTAINING SULFATE AND POTASSIUM IONS |
| abstract | THE PRESENT INVENTION CONCERNS A NEW PROCESS FOR THE TREATMENT OF BRINE CONTAINING PER LITER 16 TO 85G OF MAGNESIUM, 3 TO 15G OF POTASSIUM, 43 TO 10G OF SODIUM, 1 TO 0.5G OF CALCIUM, 15 TO 55G OF SULPHATE, 108 TO 237G OF CHLORIDE, 1.7 TO 1.6G OF BROMIDE AND 0.15 TO 0.54G OF CARBONATE, CHARACTERIZED IN THAT THE FOLLOWING OPERATIONS ARE SUCCESSIVELY CARRIED OUT: 1 MAXIMUM ELIMINATION OF SODIUM CHLORIDE BY EVAPORATION OF BRINE; 2COOLING OF THE PRECONCENTRATED BRINE OBTAINED UP TO A TEMPERATURE BETWEEN 15 AND -10C, SO AS TO CRYSTALLIZE THE EPSOMITE; 3PRECIPITATION OF UNSULPHATED CARNALLITE AND ISOLATION OF THIS CARNALLITE; 4AQUEOUS DECOMPOSITION OF THE CARNALLITE OBTAINED WITH A VIEW TO OBTAINING A PRECIPITE COMPOSED OF KCL, AND 5 SUBSEQUENT REACTION BY ANY KNOWN PROCESS, OF EPSOMITE AND KCL THUS OBTAINED IN A WAY TO PREPARE POTASSIUM SULPHATE. |
