Abstract

A system and a method separating COfrom a gas mixture using hydrates are provided. An exemplary method includes injecting a feed gas into a gas hydrate column through a feed gas line and producing hydrogen from a hydrogen outlet line. The method includes determining that water on trays in the gas hydrate column is saturated with COgas hydrates, closing valves on the feed gas line and the hydrogen outlet line, opening a valve leading to a carbon dioxide outlet line, lowering pressure in the gas hydrate column, and producing carbon dioxide from the carbon dioxide outlet line.
