The Project Tundra facility is designed to capture CO2 at a rate of about 90% from either unit at the Young Station. The CO2 would be then be stored more than a mile underground. If the project moves forward, North Dakota would be a world leader in the development of next-generation energy technologies.
Flue gas from either generator at the Milton R. Young Station is diverted to a scrubber, which cools the gas and removes impurities. The gas is then sent to an absorber where the CO2 capture takes place.
The gas flows into the bottom of a large absorber unit, which is filled with stainless steel structural packing. As the gas rises through the packing, 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 pumped to a regeneration unit. There, heat is used to break down the CO2 bonds with the solvent, and releasing pure CO2 in a gaseous state. Finally, the CO2 is sent to a compressor where it is prepared for deep geologic storage.
