Crystallization is the formation of solid particles within a homogeneous phase of saturated liquid. Its wide use has a two-fold basis, a crystal formed from an impure solution is itself pure and crystallization affords a practical method of separating w. This operation involves both heat and mass transfer. Cooling type agitated batch crystallizer set up consists of an open jacketed stirred vessel provided with water heating & cooling arrangement. The feed is prepared in the crystallizer itself with hot water and stirrer. The hot saturated solution in the crystallizer is then cooled by circulation of cooling water and crystals are formed. EXPERIMENTATION:
To study the performance of a Batch Crystallizer.
To determine the crystal yield and the efficiency of crystallizer.
