The invention relates to a method for separating a gas containing carbon dioxide by means of distillation. According to the method, the gas containing at least 50% of carbon dioxide is cooled in a first exchanger (43) so as to produce a cooled fluid, a liquid (23) derived from the cooled fluid is sent to a distillation column (25) to be separated therein, a head gas (6) is withdrawn from the distillation column and reheated in the first exchanger, a vat liquid (27), which is richer in carbon dioxide than the gas containing at least 50% of carbon dioxide, is withdrawn and at least a portion thereof is heated in the first exchanger, at least a first portion of the vat liquid is vaporized in the first exchanger in order to produce a vaporized portion, the vaporized portion (31) is sent back to the column and an NOx removal column is supplied with the liquefied cycle gas (155) produced by vaporizing and reliquefying the vat liquid from the column.
