Abstract

In a method for purifying a flow rich in carbon dioxide and containing at least one impurity lighter than carbon dioxide, the flow is cooled in a heat exchanger (7) and partially condensed, the partially condensed flow is sent to a first phase separator (9) operating under a first pressure, a gas from the first phase separator is compressed and sent to a second phase separator (31) operating under a second pressure higher than the first pressure, a first liquid (11) is sent from the first phase separator to a housing (15) operating under a pressure lower than the first pressure, and a second liquid (33) is sent to the housing.
