Abstract
Carbon dioxide is recovered from the exhaust gas in the form of liquid carbon dioxide or supercritical carbon dioxide using a rotary separator. Nitrogen recovered from the rotary separator may expand to provide cooling of carbon dioxide in a closed-loop CO2 power cycle that is used to cool off-gas upstream of the rotary separator. Recovery may power itself and may generate excess power from waste heat.
