Swenson Walker Crystallizer Pdf
Swenson-walker crystallizer: The Swenson-walker crystallizer is a cooling type, continuous, jacketed trough crystallizer. It is an example of the scrapped surface. The Swenson-Walker crystallizer is a model, specifically conceived by Swenson Co. Around 1920, having a semicylindric horizontal hollow trough in which a hollow screw.
Swenson Walker Crystallizer Model No: ETSC-74 The set-up is designed to demonstrate and stimulate the phenomena of crystallization. Swenson Walker crystallizer is a continuous type crystallizer. This operation involves both heat and mass transfer. Crystallization is the formation of solid particles within a homogeneous phase. Its wide use has a two-fold basis; a crystal formed from an impure solution is itself pure.
The setup consists of a top open jacketed round bottom trough. A ribbon mixer is provided in crystallizer trough, which rotates at low rpm for agitation of saturated solution. The saturated solution is prepared in a tank fitted with heater and a stirrer. This hot saturated solution is fed at one end of the crystallizer and flows slowly towards the other end while being cooled and is allowed to flow back in hot feed tank making the process continuous.
The mechanical design of the crystallizer has a significant influence on the nucleation rate due to contact nucleation. Swenson Crystallizers. SWENSON WALKER CRYSTALLIZER. AIM: To study crystallization process with Swenson Walker Crystallizer. APPARATUS: Swenson Walker Crystallizer.
The crystals sediments at the bottom of the trough, and can be washed out at the end of process. Arrangement for Cooling water circulation and flow measurement in jacket is made by using storage type water tank, a pump and a rota meter. Necessary instrumentation is done for temp measurement. Experiments • To study the performance of a Swanson Walker Crystallizer. • To determine the crystal yield and the efficiency of crystallizer. Features • Superb Painted structure. • Simple to operate & maintain.
