Teaching equipment : Gas/liquid absorption

 

Our categories

Gas/liquid absorption

DESCRIPTION

 

Specific operation, which allows the separation of components of a gaseous mixture through a liquid solvent, by affinity (solubility).

The gas/liquid absorption is made in back run in continuous or batch mode. Samples tapping is provided in order to make measurements of temperature and pressure. The flow rate of the fluids is measured and controlled.

The unit includes a user manual.
