👉 Recirculations are a type of system that includes both an upstream and a downstream process. In this type of system, water is circulated between two or more processes, allowing for the exchange of heat and mass in a controlled manner. Recirculation can be used to optimize energy use by reducing the amount of energy required to transport and distribute water across different stages of a process. Recirculations are often utilized in industrial processes, such as steam turbines, where they help to reduce energy consumption while maintaining
