CO2 Compressors are a critical component of a Carbon Capture, Utilization and Sequestration system.  Following separation from flue gas or other sources, pipeline transportation requires boosting of CO2 from approximately atmospheric pressure to well above the supercritical phase, which consumes a substantial amount of power.  Careful attention to CO2 compressor design is critical to maximizing efficiency and minimizing capital cost while properly addressing condensate removal, fugitive emissions and carefully managing the margin between CO2 supercritical gas and liquid phases.  This presentation will describe compressors used to compress CO2 at different points in the CCUS process.
