Title:
減らされた数のバルブおよびラインを有する擬似移動床分離のための方法および装置
Document Type and Number:
Japanese Patent JP5401326
Kind Code:
B2
Abstract:
The invention concerns a simulated moving bed adsorption separation device comprising a limited number of 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 plate valve Vi. Each line Lk comprises a flow limitation means and is connected to each of the fluid networks via a single 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. The invention also concerns a separation process using said device, in particular to separate para-xylene or meta-xylene from an aromatic C8 cut.
