Method for producing a gas

Abstract

One object of the present invention is to provide a gas-liquid separating device which can efficiently recover a target gas from a mixture containing at least a gas and a liquid in a gas-liquid coexistence state, and the present invention provides a gas-liquid separating device which separates and recovers a gas and a liquid from a mixture containing the gas and the liquid in a gas-liquid coexistence state, wherein the gas-liquid separating device includes an airtight space in which the mixture containing the gas and the liquid in a gas-liquid coexistence state is supplied and the mixture is stored as a mixture separated into gas and liquid, a supply path for supplying the mixture containing the gas and the liquid in a gas-liquid coexistence state into the airtight space, a gas recovery path for discharging the gas in the airtight space to the outside of the airtight space, a first decompressor which is provided in the gas recovery path and recovers the gas from the airtight space, a liquid recovery path for discharging the liquid in the airtight space to the outside of the airtight space, and a second decompressor which is provided in the liquid recovery path and configured to recover the liquid from the airtight space.
