Wetted Wall Absorption Pilot Plant Teaching Equipment

WWA Wetted Wall Absorption Pilot Plant Teaching Equipment


Wetted wall columns have been designed to study the absorption of air oxygen into deoxygenated water prepared with nitrogen.
Training program
This unit enables to deepen the following issues:
• Calculation of mass transfer coefficient in liquid film
