    摘要: Disclosed is a method for producing at least one gas having a low CO
    2 concentration and one or more primary fluids having a high CO
    2 concentration from a fluid which is to be treated and contains CO
    2 and at least one compound that is more volatile than CO
    2 .
    Said method comprises the following steps: a) the fluid to be treated is subjected to a first cooling process using heat exchange without the fluid undergoing a change of state; b) at least some of the fluid to be treated and cooled in step a) is cooled a second time such that a solid is obtained which contains mainly CO
    2 and at least the gas having a low CO
    2 concentration; and c) a step in which at least some of said solid is liquefied such that the one or more primary fluids having a high CO
    2 concentration are obtained. The disclosed method is characterized in that at least part of the first cooling process in step a) is carried out by heating at least some of the one or more primary fluids having a high CO
    2 concentration.
