Device and process for rinsing a simulated moving bed comprising at least two fluid distribution lines

摘要

Separator with simulated moving bed with a number of interconnected chromatographic columns or column sections (2, 4, 6), a fluid distribution plate (3) between each column section, and at least two and at most four separate circulation lines (10, 20, 30, 40) connected to the plate. Connections are as follows: Opti Circulation Circulation Circulation Circulation on Line (10) line (20) line (30) line (40) 1 Each line is connected to a different one of the two feed lines (100, 300) (for the charge and the desorbant) and two extraction lines (200, 400) (for the selected fluid and the remaining product(s)) 2 the charge remaining 2 lines (100, 200) feed line fluid containing the desorbant and (300) extraction the selected fluid line (400) respectively 3 desorbant selected 2 lines (300, 400) feed line fluid containing the charge and (100) extraction the remaining fluid line (200) respectively 4 2 lines (300, 400) 2 lines (100, 200) containing the charge and containing the desorbant and the remaining fluid the selected fluid respectively respectively The fluid circulation line carrying the chosen product includes a washing line (250) for a second inlet fluid (desorbant, fluid containing the selected fluid or remaining fluid with empoverished in selected fluid), or an exit fluid (mixture of desorbant and selected fluid). Separation process using a device as described above, where the circulation lines are washed through between or throughout each permutation of the connections.
