Post combustion carbon capture using EDBM

Solutions to the increasing demand for flue gas carbon capture

Carbon dioxide emissions are the largest contributor to global climate change. Carbon capture can make a significant contribution to combating its reduction in the atmosphere.

Post-combustion carbon capture is a process that can reduce carbon dioxide (CO₂) emissions from stationary sources such as fossil fuel power plants, thermal power plants, or industrial plants producing cement, steel, and chemicals.

Flue gas carbon capture and storage is a method of capturing and storing CO2 in one place. It is the most widespread technology among current carbon capture methods.

Amine scrubbing for CO₂ capture

Carbon capture technology using amine solvent to clean CO2 from flue gas is the most advanced and proven commercially available technology. Amine-based carbon capture technology separates carbon dioxide from the flue gas fed into the absorption column before it leaves the stack. The amine solvent is chemically bound to the carbon dioxide. The CO₂ rich solvent is then fed to the desorption column where a reverse reaction releases pure CO₂ for subsequent capture, releasing the solvent for reuse.

MEGA offers advanced bipolar electrodialysis as an innovative amine solvent regeneration technology used for industrial flue gas scrubbing technologies.

Amine solvents

Currently commercially available amine solvents are monoethalolamine (MEA), diethalolamine (DEA), triethanolamine (TEA), diglycolamine (DGA), or piperazine (PZ). MEA and TEA are the most widely used industrially as they show high selectivity and rapid reaction. However, they are sensitive to impurities and require desulphurization and denitrification to perform effectively. Our technology removes these impurities and returns pure amine back with no loss.

Ensuring process efficiency with MEGA EDBM

MEGA offers an innovative amine solvent regeneration technology by bipolar electrodialysis (EDBM) for industrial flue gas scrubbing technologies.

The main advantage of integrating bipolar electrodialysis into the post-combustion carbon capture process is to integrate it with the amine regeneration process to significantly reduce the operating costs of the entire carbon capture technology.

Using electrodialysis to purify an absorbent solution is approximately 2-3 times cheaper compared to replacing it with a new one!

Regeneration of absorbent using bipolar electrodialysis by MEGA

To maximize the efficiency of amine-based carbon capture technologies, our researchers have improved the amine regeneration process using innovative bipolar electrodialysis.

When the regenerated amine solution is reused from the CO₂ scrubber, each subsequent absorption process captures not only CO₂ but also other substances present in small quantities such as acid gases (SO₂, NO_X, ...) or other inorganic salts (sulphides, cyanates, etc.) that contribute to the formation of heat-stable salts. These impurities lead to a decrease in the absorption efficiency and to higher consumption of the amine solution.

By MEGA's EDBM, the heat-stable salts are removed and the pure amine solution is returned back with no loss!

MEGA increases the efficiency of the amine recovery process and makes this technology more economical and environmentally friendly.
