Continuous reactors are systems used in chemical processes where reactants are continuously fed into the reactor while products are simultaneously removed. This setup allows for a steady-state operation, making it efficient for large-scale production. Continuous reactors are commonly used in industries such as pharmaceuticals, petrochemicals, and food processing. These reactors can take various forms, including stirred tank reactors and plug flow reactors. They offer advantages like improved control over reaction conditions and better heat management. Continuous reactors are essential for processes that require consistent quality and high throughput, making them a vital component in modern chemical engineering.
