Vol 1 Chapter 4: Post-Combustion CO2 Seperation Technology Summary
Dag Eimer
Abstract: The post-combustion technology team (the Team) found a number of interesting ways in which the cost of carbon dioxide removal could be reduced from the base case. A number of technologies have been investigated. It is the feeling of the Team that there are many good research opportunities with respect to reducing the total cost of carbon dioxide removal. Extensive studies were completed in these areas, all based on absorption:
- Base case.
- Nexant low-cost design.
- Nexant integrated low-cost design.
- Kvaerner-Mitsubishi (MHI): a new contactor combined with a new absorbent.
The Team has also evaluated:
- Better adsorbents, and the potential of adsorption processes.
- The basis for dismissal of membranes and cryogenics for this application.
- New chemical approaches, producing a few research proposals.
- Alternative equipment technologies.
Finally, the Team has defined what is referred to as best integrated technology (BIT) based on the studied absorption technologies. BIT is not ready to be built, as some features need to be checked. The BIT concept must not be seen as the ultimate post-combustion solution as there are identified research opportunities available, and more are foreseen for the future.
