低温液化ガスをタンク内に貯蔵しておくと、タンク内に
おいて入熱により蒸発ガスが発生する。When low-temperature liquefied gas is stored in a tank, evaporative gas is generated due to heat input inside the tank.
Ｎ、、、−７−−−−−−− この蒸発ガスは通常タンク外のコンプレッサーで 。N,,, -7------ This evaporative gas is usually collected by a compressor outside the tank.

となっている。It is sucked in, pressurized, and sent to the consumption side, but the amount of evaporated gas generated when receiving low-temperature liquefied gas into a tank is several times the normal amount. For this reason, conventional evaporative gas suction and pressurization equipment is designed in accordance with the amount of evaporative gas generated at the time of receiving, and is over-equipped in normal cases other than the time of receiving.

を減少させたものである。The present invention has been proposed in view of this point, and when low-temperature liquefied gas is received into a tank, a part of the evaporated gas generated in this tank is directly transferred to the low-temperature liquefied gas to be received. By bringing them into contact and mixing, reliquefaction is achieved using the cold heat, thereby reducing the amount of evaporated gas that must be treated outside the tank.

で蒸発ガスは再液化される。1 is a receiving tank for low-humidity liquefied gas, 2 is a receiving pipe, and 3 is an ejector installed in the evaporative gas layer 5 in the upper part of the tank 1. This ejector 3 is equipped with a gas suction amount adjustment lid 4. Adjustment lid 4 No. -----'1----
---- is controllable outside the tank. or,
The tip 2' of the receiving pipe 2 is connected to the ejector 3, and when the low-temperature liquefied gas is sent into the tank 1 from the receiving pipe 2, the ejector 3 removes the evaporated gas from the gas layer 5 into the ejector 3. and ejector 3.
The low-humidity liquefied gas and the evaporated gas are brought into direct contact and mixed in the mixing tube 6 installed subsequently, and the evaporated gas is re-liquefied by the cold heat of the low-humidity liquefied gas.

The end-stream fraction may be completely liquefied by the cold heat of this stored liquid, or when sufficient re-liquefaction can be achieved within the mixing tube 6, the jet nozzle 6' of the mixing tube 6 will open as shown in FIG. It may be above the liquid.

スの処理量は通常時より若干多くなるだけである。The method for treating evaporated gas according to the present invention is based on the above-mentioned features.
The evaporated gas generated when low-temperature liquefied gas is fed into the receiving tank J is sucked into the ejector 3 by the energy of the low-temperature liquefied gas being ejected into the ejector 3, and the low-temperature liquefied gas is sucked into the ejector 3 in the mixing tube 6. Since it directly contacts and mixes with the liquefied gas and re-liquefies it with the cold heat, the amount of evaporated gas that must be treated outside the receiving tank 1 at the time of receiving is only slightly larger than usual.
