Multi criteria analysis to identify a suitable CO2 capture technology for a coal power plant

The carbon capture and storage (CCS) is viewed as the likely option for slashing CO2 emission from power plants. The capture process of CCS is very important and there is a wide range of technology options. The chemical absorption capture technology is very well developed and ready for commercial implementation in large scale power generation. There are some technology providers such as Fluor, Mitsubishi Heavy Industries, Cansolv, Alstom, Siemens etc who are commercially offering chemical absorption processes. The choice of a specific capture technology for a plant depends on many competing evaluation criteria and complicated. All commercial capture technologies have advantages and disadvantages based on their application contexts and operating conditions. In this research, a multi criteria analysis using analytical hierarchy process is performed to identify the most suitable capture process for retrofitting a power plant in Central Queensland, Australia. Information available in public domain is used for this analysis. The result shows that Fluor’s capture technology is very suitable for this application.
