Sugar cooling crystallization process was used for low sugar grade crystallization that carried out under certain conditions of higher supersaturation levels for further sugar crystallization after evaporating crystallization by decreasing sucrose solubility through temperature reduction. Recently there is a great interest with utilization of cooling and flash evaporation crystallization for white sugar production for energy cost saving in the sugar industry. This study is focusing on the utilization of an advanced sugar crystallization program to determine cooling crystallization parameters and conditions such as massecuite brix, crystal content and working temperature and pressure. A series of cooling crystallization experiments were conducted on a sugar crystallizer pilot at Al-khaleej sugar company “AKS" through 2017, 2018 seasons. Theoretical and practical simulation results are presented for sharing and discussions.
