APPARATUSES AND PROCESSES FOR THE RECOVERY OF CARBON DIOXIDE STREAMS

Processes and apparatuses for recovering a high purity carbon dioxide stream. A first separation zone that may include a cryogenic fractionation column provides the high-purity CO2 stream. A vapor stream from the cryogenic fractionation column is passed to a second separation zone to separate the CO...

More Information
Summary:Processes and apparatuses for recovering a high purity carbon dioxide stream. A first separation zone that may include a cryogenic fractionation column provides the high-purity CO2 stream. A vapor stream from the cryogenic fractionation column is passed to a second separation zone to separate the CO2 from the other components. The second separation zone may include a pressure swing adsorption unit or a solvent separation unit. The second separation zone provides a hydrogen enriched gas stream that may be used in a gas turbine. The second stream from the second separation zone includes carbon dioxide and, after a pressure increase in a compressor, may be recycled to the first separation zone.
