A method includes contacting a feed stream comprising carbon dioxide, water vapor, and one or more impurities with a first adsorbent layer followed sequentially by a second adsorbent layer to produce a product carbon dioxide stream, a rich first adsorbent layer enriched in water vapor, and a rich second adsorbent layer enriched in the one or more impurities. The first adsorbent layer may include a first adsorbent selective for water, and the second adsorbent layer may include a second adsorbent selective for the one or more impurities.
