Continuous reactors are systems used in chemical processes where reactants are continuously fed into the reactor and products are continuously removed. This setup allows for a steady-state operation, which can enhance efficiency and productivity compared to batch reactors, where all materials are processed at once. These reactors are commonly used in industries such as pharmaceuticals, petrochemicals, and food processing. They can handle large volumes of materials and are designed to maintain optimal conditions for reactions, such as temperature and pressure, ensuring consistent product quality over time.
