摘要: 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.

摘要: A method for enhancing geological storage by injecting nanoparticles to stabilize CO2 microbubbles, which belongs to the technical field of multiphase flow. The method first improves the physical properties of the fluid by pre-mixing CO2 and nanoparticles, and then the fluid is transported to the underground through high-pressure pipelines, and then CO2 microbubbles containing nanoparticles are generated through a dense perforated plate arranged by an injection well to improve the dissolution rate and sweep efficiency of the gas in the saline aquifer, so as to enhance the later mixing of the fluid. The combined injection can improve CO2 storage capacity and storage safety, and further reduce the risk of gas leakage in the reservoir.
