Compression and pumping technology options

The aim of this chapter is to analyse various CO₂ compression processes for post-combustion CO₂ capture applications for a high-power, 900 MW (Łukowicz H, Mroncz M (2012) Basic technological concepts of a “Capture Ready” power plant. Energy fuels. ACS Publications, pp 6475–6481), pulverized coal-fred power plant. Different thermodynamically feasible CO₂ compression systems will be identifed and their energy consumption will be quantifed. The detailed thermodynamic analysis presented below examines methods of minimizing the producer’s power penalty using integrated, low-power compression conceptions. The goal of the present research is to reduce the penalty through an analysis of different compression conceptions and to investigate the possibility of capturing compression heat and converting it to useful energy for use elsewhere in the plant.
