Abstract
Process for obtaining paraxylene, characterized in that it comprises the phases of separation by crystallization of paraxylene from a mixture consisting predominantly of aromatic hydrocarbons, said mixture containing paraxylene and at least another isomer of xylene, the subjection of the residue of said mixture of aromatic hydrocarbons to isomerization conditions to produce a second mixture of an isomerized enriched in paraxylene, a lighter fraction than C-8 and a heavier fraction than C-8, the introduction of said mixture into a first fractionation zone, the separation of the fraction heavier than the C-8 of the bottom of said first fractionation zone, the separation of said fraction lighter than the C-8 and of said isomerized as materials detached upwards from said first fractionation zone, the introduction of the said fraction lighter than C-8 and said isomerized in a second fractional zone The separation of the aforesaid fraction lighter than the C-8 as materials detached upwards from said second fractionation zone, and from said isomerisation of the bottom of the same zone, the mixture of said isomerized and fresh aromatic hydrocarbon fed to forming a mixture consisting predominantly of aromatic hydrocarbons, and the repetition of the successive operation.
