Process for producing para-xylene using a step in a simulated moving bed and a step of fractionation via a three-fraction column
The present invention relates to a process for producing high-purity para-xylene, comprising a single step of separation by adsorption in an SMB, with a subsequent step of separation by distillation in a first three-fraction distillation column producing at least two raffinates and optionally of two...

| Abstract | The present invention relates to a process for producing high-purity para-xylene, comprising a single step of separation by adsorption in an SMB, with a subsequent step of separation by distillation in a first three-fraction distillation column producing at least two raffinates and optionally of two isomerization steps, making it possible to improve the overall para-xylene yield of the aromatic loop and to minimize the economic impact. |
