Title: Sepn. and recovery of para-xylene
Inventor: GERARD HOTIER
IPC: C07C15/08
Filed: 1992-07-06
Abstract: The sepn. and recovery of para-xylene in a hydrocarbon charge consisting mainly of C8 aromatics and the units necessary for the procedure are claimed. The process comprises an adsorption stage from which a first and second fraction are obtd.: an isomerisation step is carried out on the first fraction and a crystallisation step on the second fraction.     More specifically, the stages are: (a) the charge (contg. meta- and para-xylene, ethylbenzene and possibly o-xylene) is contacted in at least one fluidised bed adsorption zone contg. zeolite in the presence of an adsorption solvent, the flow of which relative to charge is 1.2-2.5 in conditions such that the first fraction contains solvent-m-xylene, ethylbenzene and possible o-xylene and the second contains solvent and mainly p-xylene (75-98%) with improved productivity; (b) the first fraction is distilled to separate the solvent from the mixt. of meta-xylene, ethylbenzene and possibly ortho-xylene.     (c) The mixt. is isomerised in the presence of H2 and an isomerate is recovered which is recycled to step (a) after distn. (d) The second fraction is distilled, recovering the solvent and para-xylene with a purity of 95-98%. (e) The para-xylene is crystallised in an appropriate zone at +10 vo -25deg.C: a mother liquor is obtd. which is re-cycled to (a) and para-xylene crystals satd. with mother liquor. (f) The crystals are washed with a solvent and para-xylene recovered of a high purity.
