摘要： The invention provides an efficient gas hydrate production system using flue gas waste heat/solar absorption heat pump to compensate reservoir heat, includes a heat source absorption system, heat pump heating system and reservoir heat compensation system and realizes efficient exploitation of submarine natural gas hydrate in the way of heat compensation. The invention uses the low-grade heat energy of offshore platform to solve the problems of heat source and energy consumption in the process of natural gas hydrate exploitation by. It provides a commercial feasible scheme for large-scale exploitation of natural gas hydrate. The condenser module, evaporator module and injection well module of the invention can be flexibly increased or decreased, and can adapt to a variety of actual hydrate reservoir distribution; the injection well module adopts ball-nozzle, which can disperse and evenly inject the hot injected water into the reservoir.

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.
