A parameter Gr =Nc/W is of high importance for C sugar operation. Sucrose solubility in water is
expressed by Herzfeld number H0 (kg sucrose/kg water). Sucrose solubility in water containing non
sugars (H1; kg sucrose/kg water) varies from the one in clean water. The ratio of H1 to H0 is called a
coefficient of saturation Kn:
