<p>The present invention relates to an improved method for removing contaminants from a gaseous or liquid stream substantially comprising carbon dioxide. More specifically, the method comprises the step of subjecting the gaseous or liquide stream to an absorption step in which the absorbent is liquid carbon dioxide or a rectification step wherein the waste of carbon dioxide is minimized by utilizing a compressing means for generating a pressure difference between two streams in a reboiler.</p> |
