What SeeGee is getting at is that gas turbine exhaust is mostly nitrogen and only 3-4% CO2. You need to get rid of that nitrogen to cut volume/compression requirements.
Semi-related, was designing an amine scrubber for a CCS system with tight space limitations and did start asking questions like, “what if I only get 90% of the CO2, is that enough?”
Outside of nitrogen, you need to get rid of contaminants like water, otherwise corrosion can start getting nasty.
