METHOD OF DEWATERING OF MAGNESIUM CHLORIDE SOLUTIONS Russian patent published in 1999 - IPC

Abstract RU 2140872 C1

FIELD: methods of dewatering of magnesium chloride solutions. SUBSTANCE: dewatering is carried out by spraying of solutions in boiling layer through pneumatic jets at gas velocity in layer of 1.5-3.5 m/s. Then, dewatered product is treated with neutral or acidified initial solution of magnesium chloride taken in amount ensuring content of magnesium chloride in desired product of not less than 50%. Subjected to treatment with initial solution of magnesium chloride may be dewatered product, cyclone dust, coarse or fine fraction of desired product. In this case, solution used for, treatment may by acidified with sulfuric or hydrochloric acid. EFFECT: improved service properties of magnesium chloride. 3 cl
