Abstract: CO2 separation by forming hydrate is a new technology. There are two pathways for CO2 separation: post-combustion separation, pre-combustion separation. The basic principles of CO2 hydrate separation is presented and the progress of technical processes and energy conservation of CO2 hydrate separation is discussed. The benefits and drawbacks and the research in the future of CO2 hydrate separation are also stated.
