This method is utilized the low and higher characteristics of pressure of the temperature of seawater in the deep-sea, make seawater and greenhouse gases, particularly generate carbon dioxide hydrate with carbon dioxide, because the density of carbon dioxide hydrate is greater than the density of seawater, the carbon dioxide hydrate that generates will deposit to the seabed and seal up with solid-state form, carbon dioxide hydrate is more stable, can not work the mischief to environment, thereby reach the purpose of GHG emissions mitigation carbon dioxide.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1, the present invention is used for the system of sealing storage of greenhouse gases at seabed and using method thereof, there is a greenhouse gases gas holder 1 in its system, greenhouse gases gas holder 1 is communicated with compressor 3 by a pipeline that valve 2 is housed, be communicated with one-way valve 5 by the pipeline that pressure gauge 4 is housed again, be communicated with impeller 6 by pipeline at last.Compressor 3 is a turbocompressor, perhaps hydraulic braking compression machine.
As shown in Figure 1, the using method that is used for the system of sealing storage of greenhouse gases at seabed, charge into greenhouse gases at greenhouse gases gas holder 1, the steps include: at first to open valve 2, allow greenhouse gases enter compressor 3, greenhouse gases reach desired pressure after being compressed by compressor 3, open one-way valve 5, promoting impeller 6 rotates, greenhouse gases are fully mixed with seawater 7, generate greenhouse gases hydrate 8 fast, the greenhouse gases hydrate sinks to the seabed direction, deposit to seabed 9 at last, thereby the solid-state seabed of realizing the greenhouse gases carbon dioxide is sealed up for safekeeping.
The above greenhouse gases is carbon dioxide, or hydrogen, or methane, or ethane, or propane, or hydrogen sulfide, or hydrogen fluorine carbide (HFC
s), or hydrogen sulfide.
Among Fig. 1 10 is for installing the appropriate location of one-way valve.
Gas hydrate of the present invention is the ice shape crystal of the class non-stoichiometry cage structure that generated under certain temperature and pressure by gas (as hydrogen, methane, ethane, propane, carbon dioxide, hydrogen sulfide etc.) or effumability liquid (as HCFC-141b, HFC-134a etc.) and water.Along with the reduction of temperature, the formation pressure of carbon dioxide hydrate is also reducing.The ocean temperature at 1000 meters is about 4～5 ℃ on the sea level, and the ocean temperature at 2000 meters, sea level is about 2～3 ℃, and the ocean temperature at 3000 meters, sea level is about 1～2 ℃.Hence one can see that along with sea water advanced increase, and the temperature of seawater reduces gradually, and the global ocean mean temperature is about 3.5 ℃.In addition, along with sea water advanced increase, the pressure of seawater is also increasing, and the pressure of 1000 meters seawater is about 10.3Mpa on the sea level.The deep-sea just in time provides the temperature and the pressure condition that are fit to for carbon dioxide and seawater generate carbon dioxide hydrate.
The density of seawater is along with the variation of the salinity of seawater, temperature and pressure and change, and the density of seawater is generally at 1.01～1.03g/cm
3Between, and the front two numerical value of density of sea water is 1.0.The density of carbon dioxide hydrate is always greater than 1.1g/cm
3(at 273.0k, the density of pressure carbon dioxide hydrate when 1.113Mpa is 1.1315g/cm as temperature
3Temperature is at 283k, and the density of pressure carbon dioxide hydrate when 4.95Mpa is 1.1458g/cm
3).Certain depths in the ocean, satisfy the formation condition of carbon dioxide hydrate fully, because the density of carbon dioxide hydrate is greater than the density of seawater, the carbon dioxide hydrate that generates will deposit to the seabed downwards, with solid-state (carbon dioxide hydrate) form the greenhouse gases carbon dioxide is sealed up for safekeeping in the seabed, carbon dioxide hydrate is more stable, can not work the mischief to environment, therefore utilizing hydrate to come sequestration of carbon dioxide should be optimal method, add the deep-sea to seal the space up for safekeeping huge, so to be that carbon dioxide is optimal seal ground up for safekeeping at the deep-sea.
In addition, carbon dioxide and water reaction generate I type gas hydrate, and 1 cubic metre of carbon dioxide hydrate can comprise 160～180 cubic metres carbon dioxide under the standard condition.Therefore, the gas storage capability of per unit volume carbon dioxide hydrate is much bigger more than the solubility of carbon dioxide in water, and the per unit volume gas hydrate can realize that the solid-state of extensive carbon dioxide seal up for safekeeping.
