Post combustion technologies for CO2 capture: A technoeconomic overview of selected options

Publisher Summary This chapter discusses post combustion capture that is removal of dilute concentrations of CO 2 from low pressure combustion byproducts downstream of a combustion system represents one of the key categories of capture technologies that have been investigated by the CCP. It provides an overview of the potential application of various post combustion capture technologies applied to a series of real world scenarios firing oil or gaseous fuels, including combined cycle gas turbine (CCGT) based power generation in Norway, open cycle gas turbine operation in Alaska and refinery based process heat and power generation in the United Kingdom. A range of these technologies are reviewed, amongst others, optimized absorption systems, the application of gas/liquid membrane contactors and developmental adsorbent systems. By considering the very real engineering challenges and constraints presented by these scenarios, appropriate technologies have been identified and assessed, providing a suite of engineering designs to capture and condition CO 2 , in preparation for transportation and storage. These designs have provided the basis for deriving project economics, which have highlighted the real project costs involved with capturing CO 2 .
