Introduction
The capture of carbon dioxide (CO2) from industrial flue gases has gained significant importance due to its detrimental effects on the environment. One effective method for CO2 separation is the use of solvent-impregnated membranes. In this process, a membrane impregnated with a specific solvent acts as a selective barrier, allowing the selective passage of CO2 molecules.
Advantages of Solvent-Impregnated Membranes
- High selectivity: Solvent-impregnated membranes can selectively separate CO2 molecules from gas mixtures.
- Low energy consumption: Compared to traditional methods such as chemical absorption, this process consumes less energy.
- Ability to operate at low temperature and pressure: This method can be operated at low temperatures and pressures.
- Modular design: Membrane units are designed modularly, allowing for easy capacity expansion
