Re: Atmospheric Separations
If you can chill the air after compression such that its temperature is 250K (-23°C), then any CO2 in the compressed air will liquefy at a pressure of 12bar.
In fact, it should liquefy on the intercooler tubes of a multi-stage air compressor if pressure is taken much higher than that. To avoid building up ice on the intercooler tubes, you would want to dry the air as much as possible before compressing it. That can be done by passing it through a chiller before compression.

Re: Atmospheric Separations
Huh. So any compressed air storage system operating at high pressures will have to remove CO2 as a matter of course? Hmm... colocating storage with production and a synfuel facility as well to make use of the CO2?
Use what is abundant and build to last
