The GUNT Falling Film Absorption Unit is a high-performance training system designed to investigate gas-liquid mass transfer using the water-oxygen-nitrogen system. It simulates selective absorption and stripping processes using transparent columns for direct visual analysis, ideal for chemical engineering and environmental science education.
Product Features
- Demonstrates selective absorption of gas components from a gas mixture using a falling water film
- Ambient air is supplied via a compressor to the bottom of the absorption column
- Water flows downward as a thin film along the column's edge; air flows upward centrally
- Partial oxygen absorption occurs in the falling water film as air exits at the top
- Oxygen-rich water is collected at the base and pumped into a desorption column
- In desorption, nitrogen enters from below and rises as bubbles, stripping oxygen from water
- Oxygen passes into nitrogen due to partial pressure differences, regenerating the solvent
- Regenerated water is recirculated to the absorption column by pump
- Transparent columns provide optimal observation of absorption and desorption processes
- Air and solvent flow rates can be precisely adjusted with integrated valves and flow meters
- Oxygen concentration and temperature continuously monitored upstream and downstream
- Digital display of measured values with simultaneous LAN transmission to PC
- Includes GUNT software for data acquisition and detailed process analysis
Benefits
- Provides real-time observation and control of absorption and stripping phenomena
- Reinforces understanding of gas-liquid mass transfer, oxygen solubility, and regeneration cycles
- Enables hands-on experimentation with industrially relevant gas treatment processes
Why Choose the GUNT Falling Film Absorption Unit?
This system is ideal for demonstrating the interaction between air, water, and nitrogen in absorption and desorption processes. With full transparency and data logging via LAN, it ensures a comprehensive, educational experience for the study of gas-liquid transfer dynamics.
