Abstract: A process for the combined production of para-xylene and benzene comprises: separating a first feed, by adsorption in a simulated moving bed SMB, to produce an extract E rich in para-xylene and at least one raffinate R which is depleted in para-xylene; converting a secondary feed of toluene by selective disproportionation to produce benzene and xylenes; a) at the start of the cycle, producing a supplemental quantity of para-xylene in a crystallization unit supplied with the xylenes from the disproportionation; b) at the end of the cycle, when the adsorbant has aged: dividing the distilled extract E into a first fraction Ea and a complementary second fraction Eb; replacing the feed to the initial crystallization by the stream Ea; and recycling the xylenes from the disproportionation to the SMB. The invention enables para-xylene and benzene production to be maintained despite ageing of the SMB absorbent.

Abstract: In a simulated mobile bed separation process, perturbations are corrected in the compositions of an extract (EA) or raffinate (RB) due to the dead volume introduced by at least one recycling pump (P) or compressor for a liquid, supercritical or gaseous mixture in a closed circuit of columns. The process is characterized in that each time an extract extraction stream (EA) or that of the raffinate (RB) passes from a position immediately anterior to a position immediately posterior to each of the dead volumes in the circuit, the flow rate of the flow rate regulated recycling pump or compressor is increased for the time which the extract or raffinate remains in the position immediately posterior to the dead volume When the extract or raffinate extraction stream passes from the immediately posterior position to the dead volume to the following position, the flow rate of the recycling pump or compressor is reduced so that the flow rate regains the value which would have been applied if the dead volume had been ignored.The invention is applicable to the separation of aromatic hydrocarbons containing 8 carbon atoms.
