Chemical Reaction Engineering is a branch of engineering that focuses on the design and operation of chemical reactors. It combines principles from chemistry, physics, and mathematics to understand how chemical reactions occur and how to optimize them for industrial processes. This field is essential for producing chemicals, fuels, and pharmaceuticals efficiently and safely. Engineers in this discipline analyze factors such as temperature, pressure, and concentration to improve reaction rates and yields. They also study different types of reactors, including batch reactors, continuous reactors, and plug flow reactors, to determine the best setup for specific reactions and applications.
