Chemical Reaction Engineering

[GV_kalpana]

Chemical Reaction Engineering is a core subject in Diploma in Chemical Engineering that focuses on understanding and designing chemical reactors, which are the heart of many chemical processes. It combines chemical kinetics (the study of reaction rates) and reactor design to optimize the production of desired products. 


ExplanationChemical Reaction Engineering involves:

1. Reaction Kinetics: Study of how chemical reactions occur and the factors affecting their rates.
2. Reactor Design: Designing reactors for efficient and safe chemical processing (batch, plug flow, and continuous stirred-tank reactors).
3. Optimization: Balancing reaction time, temperature, pressure, and catalyst usage for maximum efficiency.

It is critical in industries like petrochemicals, pharmaceuticals, food processing, and environmental engineering.
