摘要： Provided is a gas separation device configured to separate a non-hydrocarbon gas from a feed gas containing the non-hydrocarbon gas through use of a gas separation membrane, in which a decrease in operating rate can be suppressed, and economic efficiency is satisfactory. A first membrane module (1) and a second membrane module (2) are arranged in parallel to each other with respect to supply lines for a feed gas. Gas lines for regeneration (14, 15) ((24, 25)), which are branched from a permeate gas line (13) ((23)) of the membrane module (1) ((2)), and which are joined to a feed gas line (21) ((11)) configured to supply the feed gas to the membrane module (2) ((1)), are provided. Under a state in which the feed gas is supplied to the membrane module (1), a permeate gas through the membrane module (1) is supplied, as a gas for regeneration, to the membrane module (2) through the gas lines for regeneration (14, 15). In this case, the membrane module (2) is brought into a non-operation state, and the membrane module (2) is regenerated.

摘要： A gas mixing device capable of safely mixing flammable gas containing, for example, methane or the like and combustion supporting gas such as oxygen-containing gas, and a synthesis gas producing device using this gas mixing device. Flammable gas containing methane or the like and combustion supporting gas such as oxygen-containing gas are supplied into a mixing vessel via a first gas supplying section and a second gas supplying section respectively, and these gases are mixed within a combustion range in the vessel to be discharged via a discharge section. In the mixing vessel, packings for forming a large number of narrow gas flow passages in the vessel are packed so that velocity of the mixed gas flowing in the vessel becomes higher than burning velocity of the flammable gas and the combustion supporting gas.
