Beschreibung
Zusammenfassung:	Process for determining the sylvine saturation in which the salt concentration in the solid matter-free crude solution through temperature determination at a temperature TM>T, and subsequently after contacting with KCl at a temperature TNS>T and heating to TM, is measured again, and from this data a saturation temperature TS is obtained. The temperature difference TS-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.
