摘要： In a method for separating a feed gas, containing nitrogen and carbon monoxide as main components, in a distillation column (15): the feed gas is cooled in a heat exchanger (3); at least a portion of the feed gas, or at least a portion of a gas derived from the feed gas, is sent to a reboiler (5) of the distillation column so as to condense the gas while producing a liquid, and optionally a gas; at least a portion of the liquid is sent to the column; a nitrogen gas-rich flow is extracted from the column; a carbon monoxide-rich flow is extracted from the column, heated in the heat exchanger, and compressed so as to provide a carbon monoxide-rich material at production pressure; the feed gas is sent, after cooling, into a first phase separator (51); the liquid is released from the first phase separator (51); the released liquid is sent into a second phase separator; and at least a portion of the liquid from the second phase separator is vaporized so as to obtain the gas to be sent to the tank reboiler.
