Multisection type climbing mechanism.
Background technology
Liquefied natural gas (Liquefied Natural Gas, abbreviation LNG), main component is methane, and it is the earth to be recognized
On most clean fossil energy.Colourless, tasteless, nontoxic and non-corrosiveness, its volume is about the 1/ of same amount gaseous natural gas volume
625, the quality of liquefied natural gas is only 45% or so of consubstantiality ponding.Its manufacturing process is that the natural gas for first producing gas field is net
Change is handled, and after being liquefied through a succession of ultralow temperature, is transported using LNG carrier.It is non-to air pollution after liquefied natural gas burning
It is often small, and liberated heat is big, so liquefied natural gas is a kind of more advanced energy.
In present world energy sources production, natural gas has accounted for 1/3, and is possible in the near future progressively by now
Very popular oil and coal is extruded into back burner.Before the year two thousand twenty, ratio of the natural gas in world's energy demand will reach
To 45%-50%.At present, natural gas annual requirement in the world's is more than 2.5 × 10m, into international trade for (6250-6500) ×
L0m, and wherein account for 33% with what LNG modes were sold.Predicted according to the 20th world's natural gas conference and related data, the year two thousand thirty
Before, the potential demand of world's natural gas will be added to 4 × 10m, and liquefied natural gas is always that one kind segments market product.It disappears
Consumption is just increased with annual 10% speed, and Global LNG demand will be increased to 2015 from 2.18 hundred million in 2010 tons
3.1 hundred million tons, 4.1 hundred million tons are can reach to the year two thousand twenty.The first half of the year in 2011, liquefied natural gas demand increases by 8.5% on a year-on-year basis, and whole year increases
It is long by 12%, mainly come from Japan, Britain and India's newly increased requirement, and Korean traditional buyer's demand growth stimulation.
Expect 2015, China's natural gas Supply Structure is the billion cubic meter of state's aerogenesis 1700, the billion cubic meter of net importation 900, natural gas
Consumption figure is up to 2600 billion cubic meters, and the proportion accounted in primary energy consumption then will rise to 7% to 8% from current 4%.
The consumption figure of Natural Gas In China in 2011 is 1313 billion cubic meters, at that time natural gas account for the consumption proportion of the disposable energy may be by
It is promoted to 10% to 15%.The prevailing traffic mode for liquefied natural gas is the water surface and land accumulating at present, mainly using LNG
Storage tank carries out storage transport to it, and LNG storage tank is mostly bulky, climbs cumbersome, on the market in reservoir surface
Climbing device is mainly the cat ladder of fixed structure, and its is simple in construction, and function is single, and exterior space is taken very under non-working condition
Greatly, and mode of operation is also very single.
