Abstract

A process for separating CO2 from a feed stream (1) containing at least CO2 and at least one lighter component chosen among oxygen, nitrogen, argon, methane, CO and hydrogen and at least one component heavier than CO2, comprises cooling the feed stream in a heat exchanger (E1) to a temperature less than -30°C, separation of the cooled feed stream producing a first liquid enriched in CO2 and a first gas depleted in CO2, expanding at least part (16) of the first liquid, producing a second liquid (23), vaporizing the second liquid in the heat exchanger (E1) producing a second gas (25), sending the compressed cooled second gas to the bottom of a scrubber column (K2) and removing a top gas (31) of the scrubber column depleted in the at least one heavier component.
