Abstract
L'invention concerne un procédé de purification à basse température du CO2, le CO2 étant séparé d'un courant d'alimentation gazeux comprenant au moins 30 % en moles de CO2 et au moins un autre gaz ayant un point d'ébullition inférieur à celui du CO2. Le procédé comprend les étapes consistant à : (i) refroidir et condenser partiellement le courant d'alimentation; (ii) acheminer le courant d'alimentation refroidi et partiellement condensé issu de l'étape (i) vers un séparateur vapeur-liquide afin d'obtenir un courant de vapeur dont la teneur en CO2 est réduite par rapport à celle du courant d'alimentation et un courant de liquide dont la teneur en CO2 est accrue par rapport à celle du courant d'alimentation; (iii) dilater au moins une partie du courant de liquide issu de l'étape (ii); (iv) séparer le courant issu de l'étape (iii) pour produire un courant de vapeur dont la teneur en CO2 est réduite par rapport à celle du courant de liquide issu de l'étape (ii), et un courant de liquide dont la teneur en CO2 est accrue par rapport à celle du courant de liquide issu de l'étape (ii); et (v) chauffer le courant de liquide issu de l'étape (iv), le refroidissement à l'étape (i) étant obtenu au moins en partie par l'échange thermique au cours du chauffage à l'étape (v) du courant de liquide issu de l'étape (iv).
