| 20080217232 | PROCESS AND DEVICE FOR SIMULATED MOVING BED SEPARATION WITH A REDUCED NUMBER OF LARGE DIAMETER VALVES AND A REDUCED LINE VOLUME - The invention concerns a simulated moving bed adsorption separation device comprising a limited number of large diameter valves. According to the invention, the device comprises a column with a plurality of sectors Sk with 2 superimposed plates Pi with a single distribution network, each sector Sk comprising an external principal bypass line Lk connected to each plate Pi of Sk via a large diameter plate valve Vi and an external secondary bypass line Mk comprising a small diameter valve VMk connected to the adjacent sector Sk−1. Each line Lk comprises a flow rate limitation means and is connected to each fluid network via a single large diameter valve. Further, the connectors of lines Lk onto the column are offset by at most 20° inside Sk to limit the volume of lines Lk, and are offset by a mean angle in the range 70° to 110° between two neighbouring sectors Sk and Sk+1 so as not to weaken the column mechanically. The plates preferably comprise panels DMEi,j with parallel segments the direction of which varies from plate to plate or per group of 2 plates. | 09-11-2008 |

| 20100101999 | NOVEL DISTRIBUTION AND COLLECTION SYSTEM IN A MULTISTAGE COLUMN FOR EQUALIZING THE RESIDENCE TIME ON EACH STAGE - The present invention consists of a device for distributing and collecting fluids at the outlet from an upstream granular bed in a multistage column having a plurality of granular beds, said device comprising a deflector, which can equalize the trajectories of the fluid stream lines from the outlet from the mixing chamber to the downstream bed of granular solid. | 04-29-2010 |
| 20100263264 | METHOD OF INCOPORATING ALCOHOL INTO FUELS HAVING A HIGH AROMATIC COMPOUND CONTENT - The method allows to incorporate an alcohol or a mixture of alcohols into fuels by minimizing the energy expenditure linked with the prior production of the alcohol or of the mixture of alcohols. One or more bases of the fuel, to which an oxygen-containing compound or a mixture of oxygen-containing compounds have possibly been added, are used to extract the alcohol or the alcohol mixture contained in aqueous solutions produced by biomass fermentation processes. After adjusting the temperature of the aqueous solution stream and of the stream containing one or more bases of the fuel through exchangers, these streams are fed into an extractor. The extract leaving the extractor is then dried and/or an oxygen-containing compound or a mixture of oxygen-containing compounds is added thereto. The raffinate leaving the extractor is sent to a water treating plant or recycled, The stream of dried fuel to which an oxygen-containing compound or a mixture of oxygen-containing compounds has possibly been added is sent to be stored. The water leaving the drying stage is sent to a water treating plant or recycled. | 10-21-2010 |
| 20110056880 | SYSTEM FOR STIFFENING THE PLATES OF A LARGE-DIAMETER MULTI-STAGE COLUMN - Device for stiffening the plates of a multi-stage column with a diameter of more than 2 meters, whereby each plate supports a particle bed and the flow of at least one fluid passes through it from top to bottom, whereby said device consists of a number of beams that are located under the plate in question, each beam having a lower surface that is shaped like a triangle. | 03-10-2011 |
| 20110108145 | SYSTEM FOR DISTRIBUTING AND COLLECTING FLUIDS IN A MULTI-STAGE COLUMN - The invention concerns a device for distributing fluids which are to supply a multi-stage column having a succession of plates, each plate supporting a bed of granular solid ( | 05-12-2011 |
