Characteristics
Good capacity and low pressure drop
- Higher capacity and lower pressure drop than ceramic saddles.
-
Multiple sizes provide ability to optimize capacity and
efficiency
based on application requirements.
Higher liquid hold-up and residence time
- Relatively high liquid hold-up allows good absorption efficiency with slow chemical reaction.
Versatile standard packing
- Lower sensitivity to liquid and vapor distribution quality allows use with conventional liquid distributors.
