CO2 Compressors are a critical component of a Carbon Capture, Utilization and Sequestration system.  Following separation from flue gas, pipeline transportation requires boosting of saturated CO2 from around atmospheric pressure to well above the supercritical phase, which consumes a substantial amount of power.  Careful attention to CO2 pipeline 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 cover the basics of CO2 compressor design to address those issues.
