Abstract
The invention concerns a simulated moving bed (SMB) separation device and process comprising a column, beds Aof adsorbent separated by plates Pwith a single distribution and extraction network for fluids, in particular feed F, desorbant D, raffinate R and extract E, and a plurality of two-way valves for distribution of said fluids, said valves being limited in number and in particular with dimensions that are smaller than in the prior art. According to the invention, the column is divided into a plurality of sectors Swith 2 superimposed plates, each sector Scomprising an external principal bypass line Lconnected to each plate Pof Svia a large diameter plate valve Vand an external secondary bypass line Mcomprising a small diameter valve Vconnected to the adjacent sector S. Each line Lcomprises a flow limitation means, and is connected to each of the fluid networks F, D, R, E via a single large diameter valve for sequential supply or withdrawal of the corresponding fluid F, D, R or E to or from the sector Sk under consideration.
