As described above, in the present embodiment, it is formed by micro channel heat exchanger due to warmer E3, and add
The case where warm device is formed by shell and tube heat exchanger compares, and can realize the miniaturization of warmer E3.
Additionally it is possible to realize the miniaturization of of gasifier 10 itself.In particular, being imported into LNG evaporator E2 has
The LNG of the pressure of 6MPaG (being 6MPa with gauge pressure) or more.Even if in the case where making the LNG gasification of such high pressure, due to heating
Device E3 is formed by micro channel heat exchanger, is added it is therefore not necessary to which previous intermediate medium formula gasifier as shown in Figure 5 is taken like that
The thickness of the heat-transfer pipe of thick warmer E3, tube sheet and shell improves the measure of pressure-resistant performance.
Therefore, although with the structure for the LNG gasification for making high pressure, it can also prevent warmer E3 from becoming enlargement.Moreover, companion
It is minimized with warmer E3 can be made, moreover it is possible to realize the lightweight of warmer E3.
Further, since warmer E3 is formed by micro channel heat exchanger, therefore, unlike intermediate medium formula gas shown in fig. 5
The warmer E3 for changing device has shell, tube sheet like that, and heat-transfer pipe does not withstand the knot of the high pressure from the direction of outer side compression
Structure, therefore, even if be imported into the gas of high pressure in warmer E3, warmer E3 will not enlargement.In addition,
In the structure of Fig. 5, not only equipment is large-scale and big weight, moreover, being difficult to reach required NG outlet temperatures in seawater hypothermic phase.
In addition, in the present embodiment, due to using steam as Secondary Heat Source medium, and as the second heat
Source medium and compared using the case where seawater or air, the heating properties in the gas of warmer E3 can be improved.In addition, i.e.
Make in cold district, can also obtain the gas using the temperature required by side.
In addition, in the present embodiment, also cutting down the effect of running expense.About this point, illustrate in detail below.
If the running expense needed in the case of the structure of present embodiment is the full heat of steam that A, the first heat source medium also use steam
Running expense needed in the case of the formula gasifier of source is B, annual running expense.
In full gasification heat (100%) in gasifier, in the thermic load point of intermediate medium evaporator E1 and warmer E3
With general respectively about 80% and about 20%.In the present embodiment, (extra large with cheap natural energy resources by the 80% of thermic load
Water) supply, the remaining 20% steam supply with high price.On the other hand, in pressure decatizing gas heat source type gasifier, by thermic load
100% supplied with the steam (90% or so of fuel thermal efficiency) of high price.
The energy efficiency of required pump power (electric power) is 4KWh/t-LNG or so, therefore, if setting electric power unit price as 10
$/KWh is then 40$/KWh, that is to say, that LNG-1 tons of gasification needs 40 yen.On the other hand, the energy of steam (fuel cost)
Amount efficiency due on the basis of rate of fuel consumption amount from consumption about 1.5% (set the thermal efficiency as 90% the case where), become
15Kg/t-LNG is then 600$/t-LNG, also at this point, setting the fuel gas unit price comprising gasification cost as 40000$/t
It is to say, gasifies LNG-1 tons and need 600 yen.
In gasifier 10 involved by present embodiment, due to being intermediate medium evaporator E1：80%, warmer E3：
20% Load Distribution, therefore, running expense A are 40 × 0.8+600 × 0.5=152$/t-LNG.On the other hand, pressure decatizing
Running expense B in gas heat source type gasifier due to be 100% steam heat source, be 600$/t-LNG.Therefore, it operates
Expense is clearly A ＜ ＜ B.
Moreover, in terms of the whole year, in the gasifier 10 involved by present embodiment, during summer is due to ocean temperature rising
Between the thermic load of medium evaporator E1 become larger, the thermic load of warmer E3 becomes smaller, as a result, running expense A is reduced.Relative to
This, in pressure decatizing gas heat source type gasifier, even if the thermic load in intermediate medium evaporator E1 becomes larger, running expense B will not
It reduces.
In addition, in the case where carrying out operating upper inevitable sub-load operating, the gasifier 10 of present embodiment
In, since the thermic load with intermediate medium evaporator E1 becomes larger, therefore the characteristic that the thermic load of warmer E3 becomes smaller operates
Expense A reduces by more than part load ratio.
In contrast, in pressure decatizing gas heat source type warmer, part load ratio is remained as, running expense B does not exceed this
Part load ratio and reduce.Since ocean temperature variation and sub-load operating are inevitable, in the practical behaviour in the whole year
In work, based on the multiplication effect, the difference of the running expense in the whole year further expands and becomes A ＜ ＜ ＜ B.
