Abstract

PURPOSE:To level the generated quantity of BOG by simultaneously executing bottom receiving in some of plural storage tanks and top receiving in others of them. CONSTITUTION:LNG pumped out of a LNG tanker enters a funnel-shaped pipe 2 through a LNG receiving line 4 and moreover a bottom feed line 6a on the side of a tank 1 as it takes in BOG in the tank 1, and then flows out into liquid on the bottom of the tank 1 at a discharge port 3. On the other hand, the above-mentioned LNG flows out into an upper space in a tank 1a through a top feed line 6 by its tip 8a on the side of the tank 1a. Valves 15a, 16a can be changed over so as to use the top feed line for the tank to accelerate the occurrence of BOG and the bottom feed line for the tank to check the occurrence of BOG.

通常時の４〜５倍の量が発生する。[Prior art and its problems] Low-temperature liquefied gas such as LNG transported by tanker is once received in a storage tank inside the base and stored there, and then vaporized and sent to the consumer side. For example, in the case of LNG at -162°C, it vaporizes due to heat input even while stored in this storage tank.
BOG is generated in the tank and the pressure inside the tank increases. Conventionally, this BOG has been treated by extracting a portion of it from the tank, raising the pressure with a BOG compressor, and then returning it to the tank after reliquefaction, or sending it to the consumption side to adjust the increase in pressure inside the tank. is taking. Normally, the amount of BOG generated in a tank is approximately constant, but when receiving LNG from a tanker, the amount of BOG generated per unit time is four to five times the normal amount.

いる。Therefore, conventionally, as shown in FIG. 3, a funnel pipe 02 is inserted into the tank 01 from the top to the bottom of the tank O1, and the LNG is connected via the funnel pipe 02 from the LNG receiving line 03 to the bottom foot line 04. LNG is received at the bottom of the tank 01, that is, into the liquid, and at the same time, the BOG at the top of the tank 01 is sucked through the upper opening 02' of the funnel pipe 02 by the ejector effect, taken into the liquid, and reliquefied, thereby increasing the throughput of BOG. Efforts are being made to reduce this.
