System for flue-gas hydrate-based desalination using LNG cold energy
A system for flue-gas hydrate-based desalination using LNG cold energy belongs to the field of hydrate technology application. The CO2 in the flue-gas is captured based on the hydrate formation. Two stage formation chambers are set to improve the hydrate formation. The two steps to purify the hydrates respectively are the gas separation and the liquid separation. The two methods of hydrate dissociation to realize the recycling of the waste heat of flue-gas and the CO2 are the heat-exchanged and the exhausted. The present invention realizes the integrated CO2 capture and seawater desalination with a proper structure and a subtle system and solves the cold energy source for hydrate-based desalination by means of using LNG cold energy. The two stage formation chambers solve the capture of CO2 in the flue-gas and guarantee the hydrate formation amounts. The two types of dissociation chambers decrease the heat emission by using the waste heat of flue-gas and realize the recycling and storage of CO2. The system will not be affected by the changes of seasons and environments and has a strong carrying capacity for the flue-gas source change. It is a system with great application value realistic.
