  • METHOD AND PLANT FOR PURIFYING UNSATURATED COMPOUNDS
    Publication number: 20100217030
    Abstract: The present invention relates to a process for purifying unsaturated compounds, said purification being performed in a plant which comprises at least two evaporators which are connected in such a way that a portion of the unsaturated compound is circulated, the vapours condensed in the first evaporator being isolated and the vapours condensed in the second evaporator being introduced into the first evaporator, which is characterized in that the mass flow with which the condensed vapours are isolated from the mixture to be purified in the first evaporator is less than the mass flow with which the condensed vapours from the second evaporator are introduced into the first evaporator.
