1. An apparatus for separating carbon dioxide from a fluid containing carbon dioxide, NO2 and at least one of oxygen, argon, and nitrogen comprising: i) a separation unit for separating at least part of the fluid into a carbon dioxide enriched stream, a carbon dioxide depleted stream comprising CO2 and at least one of oxygen, argon and nitrogen and a NO2 enriched stream;ii) a conduit for recycling said NO2 enriched stream upstream of the separation unit, and;iii) a unit for producing the fluid, wherein the conduit for recycling the NO2 enriched stream is connected to the unit producing the fluid. 2. The apparatus of claim 1, wherein the unit producing the fluid is a combustion zone of a boiler. 3. An apparatus for separating carbon dioxide from a fluid Containing carbon dioxide, NO2 and at least one of oxygen, argon, and nitrogen comprising: i) a separation unit for separating at least part of the fluid into a carbon dioxide enriched stream, a carbon dioxide depleted stream comprising CO2 and at least one of oxygen, argon and nitrogen and a NO2 enriched stream; andii) a conduit for recycling said NO2 enriched stream upstream of the separation unit, wherein the NO2 enriched stream is recycled to a unit for treating the fluid, wherein the unit for treating the fluid is a compressor upstream of the separation unit and comprising a conduit for sending the fluid to the compressor and wherein the conduit for recycling the NO2 enriched stream is connected upstream of the compressor. 4. An apparatus for separating carbon dioxide from a fluid containing carbon dioxide, NO2 and at least one of oxygen, argon, and nitrogen comprising: i) a separation unit for separating at least part of the fluid into a carbon dioxide enriched stream, a carbon dioxide depleted stream comprising CO2 and at least one of oxygen, argon and nitrogen and a NO2 enriched stream; andii) a conduit for recycling said NO2 enriched stream upstream of the separation unit, wherein the NO2 enriched stream is recycled to a unit for treating the fluid, wherein the unit for treating the fluid is a wash column.
