Evaporation process is conducted by vaporizing a portion of the solvent to produce a concentrated solution or thick liquor. Evaporation is different from distillation in that there is no attempt to separate the vapours into individual components. This work represents the sensitivity of one stirred spiral evaporator on the common changes which is obtained on feed temperature. Usual values of feed temperatures obtained from one salt Stirred Spiral Evaporator are divided into three groups of Run1, 26.8 C-28 C, Run 2, 25.2 C-26.4 C, and Run 3, 24.2 C-25 C.
