| titleOfInvention | PROCESS FOR THE SIMULTANEOUS PRODUCTION OF POTASSIUM SULFATE, AMMONIUM SULFATE, MAGNESIUM HYDROXIDE AND / OR MAGNESIUM OXIDE FROM A MIXED KAINITE AND AMMONIA SALT. |
| abstract | The present invention provides an integrated process for the recovery of potassium sulphate (SOP) ammonium sulfate and surface-modified magnesium hydroxide and / or magnesium oxide, which uses the mixed salt of kainite and ammonia as the only consumable raw materials . The process involves treating kainite salt mixed with water to obtain solid schoenite and a final schoenite liquor. The latter is desulphated using the CaC12 generated in the process itself and thereafter evaporated to obtain the carnalite crystals from which the KC1 is recovered while the liquor rich in MgC12 serves as a source of MgC1. The gypsum produced during desulphation is reacted with aqueous ammonia and CO2 to produce ammonium sulfate and calcium carbonate. The calcium carbonate thus obtained is then calcined to obtain CaO and CO2. The CaO is then quenched in decarbonated water and reacted with the MgC12-rich liquor generated above to produce the suspension of Mg (OH) 2 in aqueous CaC12. To this surface the modifying agent is added in hot conditions and, after cooling, the suspension can be more easily filtered and produces the surface modified Mg (OH) 2. The filtrate rich in CaC12 is then recycled to the previous desulphation process. The surface-modified, solid Mg (OH) 2 is then calcined to produce MgO or used as such in appropriate applications. Schoenite and KC1 are reacted to produce PCOS in the solid form while liquor is recycled to the stage of production of schoenite. |
