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 () and a second membrane module () are arranged in parallel to each other with respect to supply lines for a feed gas. Gas lines for regeneration () (()), which are branched from a permeate gas line () (()) of the membrane module () (()), and which are joined to a feed gas line () (()) configured to supply the feed gas to the membrane module () (()), are provided. Under a state in which the feed gas is supplied to the membrane module (), a permeate gas through the membrane module () is supplied, as a gas for regeneration, to the membrane module () through the gas lines for regeneration (). In this case, the membrane module () is brought into a non-operation state, and the membrane module () is regenerated.
