properties affecting Residence Time Distribution (RTD) in a series of Continuous Stirred Tank Reactors (CSTRs). The parameters under consideration include flow rate, choice of tracer material, mixing efficiency, and inlet concentration. The research is motivated by the critical role RTD plays in determining the efficiency and effectiveness of chemical reactions within reactor systems. By systematically varying these parameters, this study seeks to provide insights into how they impact the distribution of residence times, which, in turn, influences the overall performance of the reactor series. The predicted outcomes of this investigation will give a valuable insight of effect of influential factors on the resulting RTD profiles. By knowing how alterations in these parameters affect the distribution of residence times, this study helps to contribute important knowledge that can useful to improve reactor system designs and operational practices. Ultimately, this will lead to enhanced efficiency and effectiveness across a wide range of chemical processes, happening in various industries and different applications. This project employs tracer materials to monitor reactant movement within the series of Continuous Stirred Tank Reactors (CSTRs). Through careful selection, these tracers provide valuable insights into residence time distributions (RTD). Tracer concentrations will be accurately detected using a titration process, enabling the construction of detailed concentration profiles. This combined approach enhances the precision of our analysis, forming a solid foundation for drawing meaningful conclusions from the experimental data.
Residence Time Distribution is particularly significant in the context of Continuous Stirred Tank Reactors (CSTRs). CSTR reactor is a large mixing vessel that continuously blends reactants and convert them into the products. This reactor type is widely used in industries where precise control over reactions is imperative. When multiple CSTRs are connected in series, it creates a sequential flow of reactants, where the output of one reactor becomes the input of the next. Understanding how RTD interacts with a series of CSTRs is important in determining the overall efficiency and yield of chemical reactions in complex systems. By connecting CSTRs in series, we essentially create a controlled environment for reactions to progress in stages, enabling more complex chemical transformations. This arrangement finds widespread application in industries where precise control over reaction pathways and outcomes is essential for producing high-quality products. Understanding the interplay between RTD and CSTRs in series is pivotal in optimizing reactor design and operational conditions for specific chemical processes.[6][7] Industries such as chemical manufacturing, petrochemical refining, pharmaceuticals, environmental engineering, food and beverage production, and biotechnology utilize Residence Time Distribution (RTD) in Continuous Stirred Tank Reactors (CSTRs) in series. This configuration ensures precise control over reactions and product quality in processes like polymerization, catalytic cracking, drug synthesis, wastewater treatment, fermentation, and more. RTD analysis is particularly valuable in optimizing chemical reactions and ensuring consistent, high-quality outputs across a range of industrial sectors.[3]

1.INTRODUCTION In the field of chemical engineering, understanding the behavior of reactants within reactors is of importance for optimizing the industrial processes. One crucial parameter in this regard is the Residence Time Distribution (RTD), which serves as a tool in informing us about the duration each component of a mixture spends inside a reactor. This distribution is necessary in determining the efficiency and effectiveness of chemical reactions. Essentially, RTD
