Ultramodern technology will capture carbon dioxide (CO₂) produced from the generators of the Milton R. Young Station, a critical coal-based power plant that provides reliable, affordable electricity to rural communities in the north.
Flue gas from the Milton R. Young Station is diverted to a scrubber, which cools the gas and removes impurities. The gas is sent to an absorber where the CO₂ capture takes place.
The gas flows into the bottom of a large absorber unit. As the gas rises through the unit, it comes into contact with an amine-based liquid solvent. The amine bonds with the CO₂ and removes it from the flue gas.
After the amine solvent has absorbed the CO₂, it is sent to a regeneration unit. There, heat is used to break down the CO₂ bonds with the solvent, releasing pure CO₂.
Finally, the CO₂ is sent to a compressor where it is prepared for deep geologic storage.
After the CO₂ is compressed, it is transported through a short pipe to an injection site near the Young Station. There, it is sent more than a mile underground to be stored safely and permanently in North Dakota’s ideal geologic formations. Learn more about this step on the CO₂ STORAGE PAGE.
