Abstract
A method and system for purifying a carbon dioxide feed stream in which the carbon dioxide feed stream is cooled and partially condensed to remove water upstream of an adsorber to produce a dry carbon dioxide stream. The dry carbon dioxide stream is further cooled and partially condensed in a carbon dioxide purification unit to form a carbon dioxide product stream. Excess refrigeration duty from the carbon dioxide purification unit is used to cool the carbon dioxide feed stream.
