o CSTR ( Continuous Stirred Tank ) is a type of reactor used commonly in industrial processing. o It is Used Primarily For: Liquid phase reactions. Liquid phase reactions. Steady state operation. Steady state operation. Perfectly mixed operation. Perfectly mixed operation. What is CSTR?
Advantages: Good temp. control is easily maintained. Good temp. control is easily maintained. Cheap to construct. Cheap to construct.Disadvantages: Conversion of reactor to product per volume of reactor is small compared to other flow reactors. What is CSTR?
The General Material Balance: Theory of The Experiment
To Convert The Conductivity To Concentration: Theory of The Experiment
The reactor that used in this experiment was CSTR with T = 22C. and the following reaction was done: T = 22C. and the following reaction was done: The objectives of the experiment to know the reaction constant in CSTR. Experimental Procedure
The concentrations of A at Steady State: Results and Discussions CONCENTRATION OF A (mol/ml) @ Feed CONCENTRATION OF A (mol/ml) @ CSTR 5024.67
α = 5 (Batch Case). k = 1.2417X10-6 [ml^4/(s.mol^4)] (Batch Case). CA = CAo ( 1 – X ) => X = 0.5145 ν = 1 ml/s Results and Discussions
The value of k is varying in the two cases, may be because of the steady state in two cases not reached. The CSTR experiment not needed for finding the variables in this experiment (batch reactor is enough). The Recording of results must taken by using computer to get accurate results. Conclusions and Recommendations
