METHOD AND DEVICE FOR CONTINUOUS DETERMINATION OF THE SYLVITE SATURATION OF HOT SOLUTIONS FOR MONITORING AND CONTROL OF THE HOT DISSOLVING OF A CRUDE POTASSIUM SALT

摘要

The degree of sylvite saturation (D.O.S.) of the hot solution present when crude potash salts are dissolved is very accurately determined by means of the use of oscillation or acoustic velocity sensors and the dissolving and crystallisation process is controlled automatically.
