The present invention provides for methods for selectively removing CO2 from a multi-component gaseous stream to provide a CO2 depleted gaseous stream. In practicing the subject methods, an initial multi-component gaseous stream is contacted with an aqueous fluid under high-pressure CO2 hydrate-formation reaction conditions to produce a mixture of a CO2 hydrate slurry and a CO2 depleted gaseous stream. Aspects of the subject methods is that the mixture of the CO2 hydrate slurry and the CO2 depleted gaseous stream is transferred directly to a second step hydrate formation reactor in a one-stage, two-step process for further removal of CO2. Also provided are systems that find use in practicing the subject methods. The subject methods and systems find use in a variety of applications where it is desired to selectively remove CO2 from a multi-component gaseous stream.
