1. The gas absorption trainer tends to demonstrate the whole process of separating CO2 and air mixture by absorption.
2. The absorption is a process used to remove gaseous components from a gas Gas Absorption Trainer using solvent.
3. The bottom of the packed column in the trainer is filled with a gas phase made up of CO2 and air. ยป Their flow ratio can be adjusted using manual valves
4. When a sample of the gas mixture is transferred to a CO2 concentration sensor inside the electric console, readings of flows and percentage CO2 concentration are displayed on the display screen and in the software.
5. Pumped to the top of the column, where it falls through the packing material, is water (or a solution of sodium hydroxide) for the liquid phase.
6. The liquid and gas phases flow against one another. This lengthens the contact period and promotes CO2 diffusion into the liquid phase.
7. The packed absorption column is mounted vertically on a mild steel floorstanding framework and is constructed of transparent acrylic.
8. Raschig rings made of glass that measure 10 mm by 10 mm are used to fill the column.
9. These rings are an example of the random packing utilized in industrial applications for gas absorption.
10. A variable-speed submersible pump is used to pump liquid into the column from a feed tank where it is kept.
11. To give a precise measurement of the liquid flow entering the column, a sensor for an electronic flow meter is inserted in the liquid stream.
