Comparison with Absorption and Membrane Technology

The economics of the CPB concept is compared to absorption and membrane technology in this section. In order to present a comparison as fair as possible, costs are calculated based on the same cost parameters as that used in the evaluation of the cryogenic concept. 

The required input for the evaluation of CO2 capture costs via absorption technology is obtained from the Integrated Environmental Control Model developed by Rubin [23]. A 600 MW power plant with monoethanolamine (MEA) absorption was simulated, resulting in a flue gas of 666 kg/s containing 14 vol% CO2 (on a dry basis), which is similar to the flue gas composition that used in the evaluation of the cryogenic concept. The costs for all
