摘要

PROBLEM TO BE SOLVED: To provide a pressure dropping system for a carrier container free to have gas in a tank truck and the carrier container after unloading absorbed in liquid by blowing it regardless of a liquid level of a storage tank and fluctuation of gas quantity and a gas blowing device to the storage tank.;SOLUTION: A system to drop pressure by blowing gas from the inside of a carrier container 1, etc., in liquid of a storage tank 10 through a nozzle 42 is devised to release gas blown in from the nozzle 42 to the inside of liquid from a large number of diffusion holes 53, 54 formed on a cap 48 by blowing it to the cap 48 of which a lower end formed on a lower end inside the storage tank 10 opens and making it pressure in accordance with the liquid level inside of the cap 48.;COPYRIGHT: (C)2001,JPO
