AbstractMagnesiumchloride hexahydrateis a clear crystal odorless colorlessand freely soluble inwater hexonal crystals with a specific gravity of 2 41 gram per cubic centimeter molecular weight of 95 23 and melting point of 7130C Applications of magnesiumchloride include Sorel cement binder for industrial flooring and to make lightweightbuilding slabs The aim of this dissertationproject is crystallization of magnesiumchloridefor industrial applications in laboratoryscale The raw material is brine which flow underof surface of ground after separation of carnallite and sodium chloride from it Theimpurities in brine were consideredas calcium chloride becausethe amount of calciumchloride is higher than other soluble impurities Three phase systemgraphs H2O CaCI2 MgCI2 within temperaturerange of 00C to 1100 were plotted The plotted graphswere Csuper positioned and a temperature related prism of three phase systems at differenttemperatures were obtained in order to find the operating points to obtain maximummagnesiumchloride crystal with purity higher than 93 Theoretical data were used tocarry out experimentsto obtain maximum magnesiumchloride crystal by batch coolingand continuous cooling crystallization techniques Crystallization degree in batch coolingcrystallization technique within temperaturerange of 1100C to 17 0C was 29 percentand in continuous cooling crystallization techniquewithin temperaturerangeof 68 0C to 17 0Cwas 34 percent In laboratory scale the massbalance results confirms that percentageofcrystal obtained of raw material from continuous cooling crystallization technique withintemperaturerange of 680C to 170 comparedto a batchprocesswas 10 percentmore and Cin comparisonwith other methodscarried out in this project is more efficient f I 1 lP u VIIIiI I Iif l lI ln A I
