While RTD provides valuable information about flow patterns, it has some limitations:
1. Assumptions: RTD models often rely on simplifying assumptions that may not fully capture the complexities of real systems. 2. Non-Idealities: RTD analysis may not account for all non-idealities such as axial mixing, reactor geometry, and catalyst deactivation. 3. Tracer Selection: The choice of tracer and its interaction with the reactor environment can affect the accuracy of RTD measurements.
