Impeller speed is another critical parameter in catalytic processes. The speed must be optimized to balance mixing efficiency and energy consumption. Key considerations include:
- Reynolds Number: The flow regime (laminar, transitional, or turbulent) is determined by the Reynolds number, which depends on impeller speed and reactor dimensions. - Power Consumption: Higher impeller speeds increase power consumption, so energy efficiency must be considered. - Catalyst Integrity: Excessive shear forces at high speeds can damage catalyst particles, leading to reduced activity and selectivity.
