Abstract
A process for separating carbon dioxide from a fluid containing carbon dioxide, NO2, and at least one of oxygen, argon, and nitrogen comprises the steps of 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 and recycling said NO2 enriched stream upstream of the separation step.

A process for separating carbon dioxide from a fluid containing carbon dioxide, NO2 and at least one of oxygen, argon, and nitrogen comprising the steps of:
- i) 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;
- and
- ii) recycling said NO2 enriched stream upstream of the separation step
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;
- and
- ii) a conduit for recycling said NO2 enriched stream upstream of the separation unit.
