Gas Absorption

Product Description

Gas Absorption Technical Description of Gas Absorption Absorption is used to remove one or more gaseous components from a gas flow using a solvent. First of all, a CO2 and air gas mixture is produced. It is possible to adjust the mixing ratio using valves. The flow rates of the gas components are displayed. 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 counterflow 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 the vacuum 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. The water temperature can be controlled. Flow rate, temperature and pressure are continuously measured Specification of Gas Absorption Separation of CO2/air mixture by absorption in counterflow with waterProduction of gas mixture using CO2 from compressed gas cylinder and ambient airAdjustment of mixing ratio using valvesCompressor for delivering the gas mixture into the absorption columnContinuous solvent regeneration in circuit with desorption column under vacuum1 pump for desorption column and 1 pump for returning solvent to absorption columnWater temperature control with heater and refrigeration system Technical Data of Gas Absorption Absorption column Height: 2x 750mm, internal diameter: 80mm Desorption column Height: 750mm, internal diameter: 80mm 2 pumps (absorption/desorption) Max.
