Patent number: 9714390Abstract: A process for purifying a hydrocarbon feed, using a first adsorption unit with first and second adsorption columns respectively filled with first and second adsorbent solids by simultaneously: a) treating the liquid phase hydrocarbon feed in the first adsorption column by contact with the first adsorbent solid to adsorb at least a portion of impurities present and to produce hydrocarbon effluent which is depleted in impurities; b) treating a secondary liquid hydrocarbon feed constituted either by a fraction of the hydrocarbon feed or by a fraction of the hydrocarbon effluent and depleted in impurities to purify the secondary liquid hydrocarbon feed; c) heating the treated secondary liquid hydrocarbon feed from step b); d) regenerating the second adsorbent solid of the second adsorption column which comprises impurities with the secondary hydrocarbon feed heated in step c) to desorb the impurities to produce an effluent with impurities.Type: GrantFiled: March 11, 2013Date of Patent: July 25, 2017Assignee: AXENSInventors: Isabelle Villechange, Tom Frising

Patent number: 9227891Abstract: Process for the production of paraxylene from a C8 aromatic feedstock that comprises the following stages: A stage for separation by adsorption in a simulated moving bed SMB that produces an extract that contains at least 95% paraxylene and at least one raffinate R that contains ethylbenzene, A recycling of raffinate to the SMB separation stage after isomerization, in which R is separated in membrane separation means to obtain a first fraction F1 that is relatively high in ethylbenzene, which is purged, and an additional fraction F2 that is relatively low in ethylbenzene, which is recycled to the SMB after a single isomerization, preferably in the liquid phase.Type: GrantFiled: October 17, 2008Date of Patent: January 5, 2016Assignee: IFP BNERGIES NOUVELLESInventors: Philibert Leflaive, Arnaud Baudot, Helene Rodeschini, Tom Frising

Patent number: 8821732Abstract: A device (SMB) for separation by simulated moving bed adsorption comprises a plurality of elementary zones Zi in series operating in a closed loop, each of said zones comprising, between two successive fluid injection or extraction points, a unique bed Li of adsorbant solid with volume VAi and a non-selective free volume Vi, in which the majority of the zones are ordinary elementary zones each having an identical volume VA of the same adsorbant S, and a substantially identical non-selective free volume equal to V; the device also comprises at least one particular elementary zone Z0, termed the particular elementary zone, comprising a non-selective free volume V0 which is greater than V, and a unique bed L0 of adsorbant S0 with volume VA0 which is less than VA, S0 having a volume adsorption capacity C0 which is greater than that, C, of S, such that the overall adsorption capacity C0×VA0 of Z0 is closer to the overall adsorption capacity C×VA of each of the ordinary elementary zones than the overall adsorptionType: GrantFiled: December 1, 2008Date of Patent: September 2, 2014Assignee: IFP Energies NouvellesInventors: Philibert Leflaive, Tom Frising, Damien Leinekugel-Le-cocq, Gerard Hotier
