Description
Technical field
Technical field is stored and utilized the present invention relates to liquefied natural gas, and in particular to a kind of LNG gas stations BOG minisize thermoelectric combined production devices.
Background technology
BOG （Boil
Off Gas, flashed vapour）Refer to LNG（liquefied
Natural gas, liquefied natural gas）Liquid pressurizes the cryogenic gas after being gasified below critical-temperature, because LNG is cryogen, although LNG filling gas station equipments have good insulation, during storage and operation, because natural heat transfer and system cooling need, all inevitably result from a number of gas, that is BOG, with the increase of BOG quantity, raises the temperature and pressure in LNG storage tank tank, when reaching to a certain degree, it has to release BOG to reduce pressure inside the tank.
BOG is in itself a kind of very clean fuel, it is discharged into air and is not only a kind of meaningless waste, and fuel gas is discharged into air, with potential danger, counted according to certain LNG gas station, the BOG quantity of annual discharge is close to the station year for the 5% of LNG total amounts, economic loss exceedes 40 × 104 yuan, additionally, main component is methane in BOG, and methane is a kind of very strong gas of greenhouse effects, the greenhouse effects coefficient (GWP) of methane is 21 times of carbon dioxide.
Therefore, what we must pay attention to BOG diffuses problem, and this not only conforms with the principles and policies of energy-saving and emission-reduction, is also the important measures of the economy and security that improve device.
At present, mainly have using the method for LNG gas stations BOG：
（1）Directly output technique, i.e. BOG gases are by after pressure needed for compressor direct weighting to gas ductwork, being input into urban pipe network.
（2）Storage of higher pressures, i.e. gas station itself have CNG gas storage facilities, BOG can be recovered into high-pressure gas well（Or bottle group）It is interior, as CNG supplementary devices.
（3）After BOG draws in re-liquefied technique, i.e. storage tank, compressor boost is first passed through, then cooled down by expanding machine and heat transmission equipment, BOG liquefied again for LNG returns to storage tank.
Method（1）With（2）BOG can be directly utilized, wherein the（1）BOG directly have input urban pipe network by the technology of kind, change gas station property, generally requires increase fire cistern etc. and just meets relevant specification of country requirement, the（2）Planting technology LNG gas stations needs to be arranged to L-CNG gas stations, is not suitable for the station without CNG automobile aerating demand.
Method（3）Using the re-liquefied BOG of compression set, the current technical matters installation cost is high, and power consumption, it is adaptable to which small-sized LNG gas stations economy is not high is relatively applied to Large LNG gasification station.
