  • Process and apparatus for the continuous determination of the sylvine saturation of hot solutions for monitoring and controlling the hot solubilizing of a crude potash salt
    Patent number: 5614104
    Abstract: Process for determining the sylvine saturation in which the salt concentration in the solid matter-free crude solution through temperature determination at a temperature T.sub.M >T, and subsequently after contacting with KCl at a temperature T.sub.NS >T and heating to T.sub.M, is measured again, and from this data a saturation temperature T.sub.S is obtained. The temperature difference T.sub.S -T serves as a measure for the sylvine saturation degree. In this manner, the sylvine saturation degree can automatically be measured in intervals of seconds and can serve as a control value for the addition of crude salt in a hot solution process.

  • Method for the purification and/or electrolysis of an aqueous potassium chloride solution
    Patent number: 5482696
    Abstract: The present invention concerns a method for the purification and/or electrolysis of an aqueous potassium chloride solution, in which the sulphate ions are removed from the aqueous potassium chloride solution by precipitation as potassium sulphate and/or as a potassium sulphate-containing salt mixture and/or as a potassium sulphate-containing compound.
