A CO2 absorber is a device or material designed to capture and remove carbon dioxide (CO2) from a gas mixture. This process is crucial in various applications, including industrial emissions control, life support systems, and scientific research.

There are several types of CO2 absorbers, broadly categorized by their working principle. Chemical absorbers typically use solutions or solid materials that react with CO2 to form a stable compound. For example, amine scrubbers, commonly used in industrial settings, employ amine-based solutions that chemically bind with CO2. Solid sorbents, such as zeolites or activated carbons, can also adsorb CO2 onto their surfaces through physical or chemical interactions.

Physical absorption involves dissolving CO2 into a solvent without a chemical reaction. This method is often used when CO2 concentrations are high. Another approach is membrane separation, where a semi-permeable membrane allows CO2 to pass through while retaining other gases. Biological CO2 absorption utilizes living organisms, like algae or plants, to consume CO2 through photosynthesis.

The choice of CO2 absorber depends on factors such as the concentration of CO2, the presence of other gases, the required efficiency, operating temperature and pressure, and cost considerations. The captured CO2 can then be released for reuse, sequestered underground, or further processed, depending on the specific application and the absorbent material used.
