As Absorption is used to remove one or more gaseous components from a gas flow using a
solvent. In this Apparatus first of all, a CO2 and air gas mixture are produced. It is possible
to adjust the mixing ratio using valves. The flow rates of the gas components are displayed
on LCD Display.
A compressor delivers the gas mixture into the lower section of the absorption column. In
the column, part of the CO2 is separated in the counter-flow with the solvent. Water is used
as the solvent. The CO2 is absorbed by the downward flowing water. To separate the
absorbed CO2, the charged water is then fed from the lower section of the absorption column
into a desorption column. As the pressure is reduced and the temperature is increased, the
solubility of the CO2 falls. A heater heats the water. A water jet pump generates negative
pressure in the desorption column and causes the CO2 gas to be emitted from the water. A
pump then delivers the regenerated solvent back into the absorption column.
