  • Method for producing purified ethylene through thermo-coupled distillation and ethylene-producing apparatus using the said method
    Patent number: 4460396
    Abstract: The present invention relates to a method and an apparatus for producing ethylene. This apparatus comprises essentially a phase separator connected to an ethylene fractionating unit. The fractionating unit comprises a first or lower-pressure fractionating column and a second or higher-pressure fractionating column, the second column being fed with an intermediate liquid fraction from the first column and having its head connected to the heating circuit of the reboiling system associated with the first column to at least partially condense the head fraction of the second column. Thus, the invention allows high-purity ethylene to be produced with minimum energy consumption.
