Integrating MEA Regeneration with CO2 Compression and Peaking to Reduce CO2 Capture Costs.

DE2005842857

Publication Date	2005
Page Count	100
Abstract	Capturing CO(sub 2) from coal-fired power plants is a necessary component of any large-scale effort to reduce anthropogenic CO(sub 2) emissions. Conventional absorption/stripping with monoethanolamine (MEA) or similar solvents is the most likely current process for capturing CO(sub 2) from the flue gas at these facilities. However, one of the largest problems with MEA absorption/stripping is that conventional process configurations have energy requirements that result in large reductions in the net power plant output. Several alternative process configurations for reducing these parasitic energy requirements were investigated in this research with the assistance of the Platte River Power Authority, based on recovering energy from the CO(sub 2) compression train and using that energy in the MEA regeneration step. In addition, the feasibility of selective operation of the amine system at a higher CO(sub 2) removal efficiency during non-peak electricity demand periods was also evaluated.
