摘要： A process is disclosed for the production of potassium sulfate from potassium chloride by means of a sulfate-laden anion exchanger, according to which as reaction solution, the exchanger is intensively contacted with a saturated potassium chloride solution, after saturation with potassium sulfate, and thereupon again separated, whereupon from this solution the crystals formed therein are separated, while the depleted anion exchanger is regenerated by intensive contact with a magnesium sulfate solution.

摘要： A process for increasing the exchange yield in ion exchange processes is disclosed wherein at least one reaction fraction stored with the previous carrying out of the same exchange reaction, a solution of the exchanging ions supplied from outside and water are delivered to a washed ion exchanger bed which is filled with water and which is charged with the ions which are to be exchanged; and after the discharge from the bed of the water and of a solution obtained as product, the same number of reaction fractions with the same volume is collected and stored as the number as that previously supplied, in order to be delivered as previously with the next carrying out of the same exchange reaction in the identical manner and in the same sequence, and wherein displacement occurring in the direction of flow and relatively to one another of those liquid particles which are delivered simultaneously or in immediate succession to the bed is substantially prevented until the discharge from the container of the bed is reached, and the co-ion content of the reaction fraction or fractions is kept constant by keeping constant the volume of the reaction fraction or fractions, of the solution supplied from outside and of the liquids discharged from the system and of the co-ion content of the solution supplied from outside.

摘要： In an ion exchange process wherein an ion exchange bed is successively charged and discharged during an exchange cycle with an ion, here designated as "X" ion, with "Y" being used to designate the replacing ion and "Z" the oppositely charged ion associated with X and Y, by passing aqueous solutions of the ions through the bed, with the flow thereof during charging being in one direction and during discharging in the opposite direction; the improvement with respect to the discharge portion of the cycle starting with the bed charged with X ions and filled with water substantially free of X, Y and Z ions, comprising passing at least four groups of fractions through said bed, as follows:1) a first feed group of fractions, containing X, Y and Z ions, the concentration of Z ions remaining substantially constant, the concentration of X ions successively decreasing downwardly to or near to zero and the concentration of Y ions correspondingly increasing.2) a second feed group of fractions containing Y and Z ions at the concentration of Z ion substantially equal to the concentration of said ions in the previous group and free of X ions, being introduced as feed to the process.3) a third feed group of fractions containing Y and Z ions, the concentration of which successively decrease to or near to zero, and4) a fourth feed group of fractions consisting essentially of pure water free of X, Y and Z ions;And recovering from the bed at least 3 effluent groups of fractions, as follows:A) a first effluent group of fractions which may contain the displaced water content of the bed and contains a solution containing predominantly X ions and minor amounts of Y ions, both associated with Z ions, which group is at least in part removed from the process as product,B) a second effluent group of fractions, identical to the first feed group, andC) a third effluent group of fractions, identical to the third feed group,And collecting the second and third effluent groups and using the same in a subsequent discharge portion of a cycle.The charging portion of the cycle may be improved in the same way.
