Abstract: A leakage inspection method and leakage inspection device for container to be inspected are provided. When a container to be inspected having a deformable flexible part is to be inspected for leakage, the container to be inspected is filled with an inspection gas containing helium, the container to be inspected, which has been filled with the inspection gas, is disposed in an inspection chamber partitioned from the outside, and an upward flow of a carrier gas is formed from the lower part to the upper part of the container to be inspected. A leakage of the inspection gas filled in the container to be inspected is then detected on the basis of the result of measuring the concentration of helium in the carrier gas collected at a position higher than a position where the carrier gas is fed into the inspection chamber.

Abstract: For estimation of the gas emission amount from a storage tank for storing a liquid containing the volatile compounds therein, preconditions involving a tank shape of the fixed roof type storage tank and a working pressure of a relief valve are set in a first step, and initial conditions for storage volumes, temperatures, and pressures of the liquid and a gas inside the storage tank are set in a second step. In a third step, an inflow or outflow heat quantity to or from the liquid and the gas inside the storage tank is determined so that a mass transfer amount between the liquid and the gas is obtained through CFD analysis. In a fourth step, whether or not the relief valve is actuated and the gas emission amount through the relief valve are obtained based on the mass transfer amount.
