Abstract
An evaporated gas supply method in which the liquid seal of an evaporated gas can be effectively avoided, is provided. According to the present invention, there is provided an evaporated gas supply method in which an evaporated gas having a primary pressure filled in a cylinder is reduced in pressure to a secondary pressure through adiabatic expansion, and the evaporated gas having the secondary pressure is supplied to a predetermined consuming installation, and which comprises a step of cooling down an evaporated gas in a cylinder, whereby the enthalpy of the evaporated gas (2) filled in the said cylinder is increased over an enthalpy of the secondary pressure on the saturated vapor line in a pressure-enthalpy diagram of the same evaporated gas, and a step of adiabatically expanding the evaporated gas filled in the cylinder so that its pressure is reduced, and supplying the evaporated gas having the reduced pressure to said consuming installation.
