Mastering Mass Transfer With the AFF245 Gas Absorption Trainer

Mastering Mass Transfer With the AFF245 Gas Absorption Trainer
In the ever-evolving landscape of chemical engineering and environmental technology, understanding the principles of gas absorption is fundamental. This process, crucial for removing gaseous pollutants from industrial emissions, requires a deep theoretical knowledge complemented by practical, hands-on experience. To bridge this gap between theory and application, advanced Technical Teaching Equipment is essential. One such standout solution is the AFF245 Gas Absorption Trainer, a comprehensive workbench designed to deliver an immersive educational experience.
I.Product Introduction
The AFF245 is designed to demonstrate the critical process of absorption—the removal of one or more gaseous components from a gas stream using a solvent. In this specific trainer, students can observe a simulation of an industrial flue gas treatment process. The system generates a controlled mixture of carbon dioxide (CO2) and air, with the mixing ratio easily adjustable via valves and the flow rates clearly displayed. This mixture is then delivered by a compressor to the lower section of the absorption column. Here, the magic of mass transfer occurs as the gas rises against a downward flow of water (the solvent), allowing the CO2 to be selectively absorbed.
However, the learning doesn't stop at absorption. A key feature of this apparatus is the complete regeneration cycle. The CO2-rich water is fed from the bottom of the absorption column to a desorption column. Students can observe the inverse relationship between temperature/pressure and gas solubility. As the pressure decreases and a heater raises the temperature, the CO2 is expelled. A water jet pump creates the negative pressure required, and the regenerated water is returned to the absorption column. This closed-loop cycle effectively demonstrates a true industrial application.
II.Technical Specifications
To ensure proper installation and operation within a classroom or laboratory setting, the AFF245 meets specific technical requirements. The unit requires a Single-phase Three-wire AC220V 50Hz power supply (cable of 6mm² or larger). The operating environment should be stable, with an ambient temperature between -10℃ and +40℃ and relative humidity below 85% (25℃). The system has a compact footprint with overall dimensions of 1920mm X 790mm X 2300mm and a weight of less than 290kg, making it a substantial but manageable addition to any learning facility.
III.Accessories and Practical Application
The AFF245 is a complete system comprising a wide array of components that work in harmony. The main body of the equipment features two distinct columns: an Absorber Tower and a Separation Tower . Key control instruments include a Temperature Display Instrument and a Pressure PID Control Instrument . Fluid movement is managed by several pumps, including the Absorber Tower Pump and the Separation Tower Pump . Vital process parameters are monitored using two Gas Flow Meters and two U-Type Level Gauges for pressure loss measurement. The system also includes crucial auxiliary components such as a CO2 Dryer Filter , a Heater , a Plate Heat Exchanger , and an Electric Proportional Valve for precise process control.
To provide a complete turn-key experience, the product also comes with extensive Product Accessories. This includes a Digital Multimeter , necessary Water Pipes and Power Cable Female Connectors , Carbon Dioxide Detectors , and Pressure Reducing Valves . The inclusion of Gas Tanks ensures the system is ready for operation upon delivery.
This system is not just a piece of machinery; it is a comprehensive tool for Vocational Training Equipment and Industrial Training Equipment. The primary experiment is the Carbon Dioxide Absorption and Separation Experiment, which allows students to investigate the effect of variables like liquid flow rate, gas flow rate, and temperature on absorption efficiency.
