Teaching equipment : Gas/liquid absorption demonstration

Gas/liquid absorption demonstration

DESCRIPTION   Specific operation, which allows the separation of the components of a gaseous mixture through a liquid solvent, by affinity (solubility). The unit enables the absorption of ammonia or carbon dioxide, mixed with air, through the use of an aqueous solvent. The unit is designed to familiarize students with the hydrodynamics of a column and with the process of absorption. The flow rates of the fluids are measured and controlled : the unit is monitored by manometers and thermometers. Technical documentation and instructions are provided.
