Description
Technical field
The utility model relates to BOG comprehensive treatment equipment field, the device of the BOG that specifically a kind of integrated treatment LNG receiving station produces.
Background technique
LNG(LNG Liquefied natural gas) be a kind of efficient, clean strategic energy, LNG trade also becomes the new focus of global energy markets.At present, domestic LNG industry development is swift and violent, and the coastal LNG receiving station that builds just is energetically conducive to China and realizes energy supply diversification, ensured energy security greatly.Meanwhile, LNG greatly develops the development that has also promoted national economy, has both been beneficial to the raising of living standards of the people, meets again country about energy-saving and cost-reducing industrial policy.
LNG receiving station is at the initial stage of building up, and because huge outer defeated pipeline network construction lags behind, makes the receiving station temporarily cannot be defeated outward, also just cannot process according to conventional method the BOG(boil-off gas of generation).If not newly-increased BOG processing equipment, is merely able to torch emptying, be not only unfavorable for environmental protection, but also caused a large amount of energy wastes, improve enterprise's production cost.
Summary of the invention
Technical assignment of the present utility model is for above deficiency, provide a kind of operating method flexibly, the device of the BOG that produces of energy-saving and cost-reducing a kind of integrated treatment LNG receiving station.
The utility model solves the technological scheme that its technical problem adopts: the device of the BOG that this integrated treatment LNG receiving station produces comprises LNG storage tank and low pressure BOG compressor, described LNG storage tank is communicated with low pressure BOG compressor by pipeline, low pressure BOG compressor is communicated with the suction port of BOG liquefaction plant by pipeline, and the liquid outlet of BOG liquefaction plant is communicated with LNG storage tank by pipeline.
Described BOG liquefaction plant is made up of high pressure BOG compressor and liquifier, and the suction port of high pressure BOG compressor is communicated with low pressure BOG compressor by pipeline, and the air outlet of high pressure BOG compressor is communicated with the suction port of liquifier by pipeline; The liquid outlet of liquifier is communicated with LNG storage tank.
On pipeline between described high pressure BOG compressor and liquifier, be communicated with side pipe line, side pipe line is finally connected to pipe network.
On described side pipe line, modulating valve is installed.
The device of the BOG that a kind of integrated treatment LNG of the present utility model receiving station produces compared to the prior art, have reasonable in design, simple in structure, be easy to operation, operating method flexibly, the feature such as energy-saving and cost-reducing.
