2. What we will talk about ? o What Is CSTR? o The Experiment That Was Done: Theory. Theory. Experimental Procedure. Experimental Procedure. Results and Discussions. Results and Discussions. Conclusions and Recommendations. Conclusions and Recommendations. Introduction

3. 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?

5. 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?

6.  The General Material Balance: Theory of The Experiment

7.  For CSTR: Theory of The Experiment

8.  To Convert The Conductivity To Concentration: Theory of The Experiment

9.  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

11. Results and Discussions

12.  The concentrations of A at Steady State: Results and Discussions CONCENTRATION OF A (mol/ml) @ Feed CONCENTRATION OF A (mol/ml) @ CSTR 5024.67

13.  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

14.  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
