A chemical reactor is a vessel designed to facilitate chemical reactions. It provides the necessary environment for reactants to interact, often involving heat, pressure, and mixing. Reactors can vary in size and design, depending on the specific reaction and desired output. Common types include batch reactors, continuous reactors, and plug flow reactors. In industrial settings, chemical reactors are crucial for producing a wide range of products, from fuels to pharmaceuticals. They are often equipped with monitoring and control systems to ensure optimal conditions for the reaction. Safety measures are also essential to manage risks associated with chemical processes.
