1. A supersonic CO2 separation system comprising:
a supersonic device comprising:
an entrance for a low pressure gas stream comprising CO2;a shroud;a centerbody;a converging/diverging annular duct between the shroud and the centerbody;a capture slot configured and positioned to remove particles of solid CO2 to form a solid CO2 stream; andan exit for a supersonic CO2-depleted gas stream; a diffuser configured and positioned to reduce a velocity of the supersonic CO2-depleted gas stream to a subsonic speed, and exhibiting a subsonic gas stream exit; an ejector apparatus comprising:
an ejector inlet connected to the subsonic gas stream exit;a high pressure fluid inlet duct for inducing a low pressure; andan ejector apparatus exit; a swirl generator within the converging/diverging annular duct; a capture duct comprising an inlet connected to the capture slot, a connection duct tangential to the inlet, and an outlet tangential to the connection duct; a cyclone particle separator comprising:
a separator inlet connected to the outlet of the capture duct;a separator exit for a product stream comprising solid CO2; anda slip gas exit; and a slip gas recirculation line extending from the slip gas exit and partially through the centerbody of the supersonic device along a centerline of the centerbody, sidewalls of the slip gas recirculation line connected to injection holes within the centerbody exiting into a diverging portion of the converging/diverging annular duct.
