Job Description

Cryogenic Carbon Capture

Cryogenic Carbon Capture™ (CCC) is a post-combustion technology that has the potential to reduce carbon emissions from fossil-fueled power plants by 95–99%, at half the cost and energy of current state-of-the-art carbon capture processes. In addition, CCC also removes other pollutants, such as SOX, NOX, and mercury.

Simplified process flow diagram of Cryogenic Carbon Capture.
  1. The flue gas is dried.
  2. The flue gas is cooled first in a recuperating heat exchanger, then further cooled in a proprietary desublimating heat exchanger.
  3. During the cooling, up to 99% of the CO2 forms a solid and is separated. Pollutants such as mercury, SO2, NO2, Hg, and HCl are also removed at this point.
  4. The CO2 is pressurized to above 70 bar.
  5. The cold products, supplemented by an external cooling loop, cool the incoming flue gas. The solid CO2 melts during this step.
  6. The warm, liquid CO2 is pressurized to the final delivery pressure: normally 150 bar.
