Description
Technical field
The present invention relates to a kind of liquefied gas carrier unloading regas systems.
Background technique
Often a good distance off, conveying are usually carried out by pipeline for the place of production of natural gas and area of consumption, and gaseous gas is in land
On conveyed in pipeline from reservoir.However, many reservoirs are located at remote region or the area with restricted accessibility
Domain, the utilization or technically extremely complex or economically without benefit including pipeline.So, a kind of very universal
Technology is that natural gas liquefies at or near production scene, and by LNG in the specially designed storage being usually located on seagoing vessel
Market is transported in tank.It include by gas compression and being cooled to cryogenic temperature, such as -160 DEG C by natural gas liquefaction.Therefore, LNG
Delivery vehicle can transport the LNG of enormous amount to destination, and in the destination, cargo is discharged into land jar special, later
It is conveyed with LNG haulage vehicle by highway or railway abutment or by re-evaporation and for example, by pipeline.Preferably way is
Liquid goods is unloaded to before continental line the re-evaporation LNG on seagoing vessel, LNG stream is through one or more evaporators being located on ship.
Seawater around cargo ship flows through the evaporation for LNG being heated and being flashed to before being unloaded to land based installation natural gas
Device.Applied to marine LNG receive with processing, land LNG receiving station resource allocation, marine mining natural gas processing and transport sea
Floating type regasification plant becomes more important, and prospect is very wide.
Existing main heating and gasifying device is that seawater is passed through heat exchanger, is exchanged heat with intermediate medium and LNG, such gasification
Being affected for the factors such as the vaporization ability climate of device, reduces with temperature, vaporization ability decline, and Tube Sheet of Heat Exchanger when work
Certain positions in road may freeze, especially heat exchanger latter half, reduce heat-transfer effect, therefore the Inlet water of usually device
Temperature should be controlled at 5 DEG C or more, and for ocean temperature be lower than 5 DEG C the case where, existing lng regas system can not make
With.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of liquefied gas carrier unloading regas systems, which can be in sea water temperature
It can also be used when spending lower.
