ABOUT THE COURSE:
The course intends to present the UG/PG students of Chemical Engineering to the basic principles of Chemical Reaction Engineering from a critical thinking-based approach by bringing in as many possible examples drawn from nature, day to day life, and industry. A learner, first gets a chance to appreciate the roles of thermodynamics, fluid dynamics, heat transfer, mass transfer in controlling the rate of reaction by using basic understanding and logical reasoning during the opening of most of the topics. With development of qualitative appreciation of the topic a learner is persuaded to quantify it by developing mathematical expressions to describe the reaction in step-by-step approach. Usually, a topic ends with solving numerical examples and encouraging them to develop mathematical modelling framework for reaction engineering problems they can relate with.
The course begins with the understanding of thermodynamics and how it influences a chemical reaction. Examples of industrially important reactions is going to be discussed for direct relevance of chemical reaction engineering as a core subject, where kinetics and reactor design form the central idea. Liquid phase homogeneous reaction in ideal isothermal reactor is considered as reference for simplifying the introduction of concepts like mixed flow, plug flow, sizing of reactors, network of reactors, series-parallel reactions. The understanding on heterogeneous reactions is developed by starting from analysis with a single particle or drop or bubble. The different steps involved in a heterogeneous reaction are analyzed to find out the controlling factor which influences designs of reactors like Packed bed reactor or Fluidized bed reactor. The ideas of non-ideality of reactors, catalytic reaction, bio chemical reactions are also covered with adequate examples. Emerging concepts such as sustainability and green chemical processes are also going to be highlighted.
