Classification of stirring paddles for hydrogenation reactors

Hydrogenation reactor agitators are essential components in chemical and pharmaceutical processes, designed to achieve efficient mixing in liquid-liquid and liquid-powder reactions. These agitators are classified based on their blade structure, which includes flat blade, angular blade, curved blade, and helical blade designs.

- **Paddle and turbine agitators** typically feature flat or angular blades.

- **Propeller, screw, and ribbon agitators** are equipped with helical blades.

The blade structure can be further categorized as either **integral** or **split**. Split blades are particularly useful for large agitators, as they allow direct attachment to the agitator shaft without the need to remove couplings or other components, simplifying installation and maintenance.
