METHOD FOR RECEIVING LOW TEMPERATURE LIQUEFIED GAS SUCH AS LPG OR THE LIKE FROM TANKER INTO STORAGE TANK

摘要

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.
