Abstract
A simulated moving bed chromatographic separation system for separating from a feedstock the constituents thereof, comprising packed beds filled with separating fillers, is provided, by which the separation performance of the packed beds can be evaluated without removing the packed beds from the circular fluid passage. This system is further provided with the circular fluid passage having at least four packed beds connected in series and endlessly to each other, a desorbing liquid introducing port, an extract draw-out port for drawing out the extract containing a larger amount of a constituent strongly adsorbed on the fillers, of constituents contained in a feedstock from the circular fluid passage, a feedstock introducing port for introducing the feedstock into the fluid circulating passage, and a raffinate draw-out port for drawing out the raffinate containing a larger amount of a constituent weakly adsorbed on the fillers, of the constituents. The desorbing liquid introducing port, extract draw-out port, feedstock introducing port and raffinate draw-out port are arranged so that these ports may be intermittently shifted on the fluid circulating passage without changing this order. This system is also provided with packed bed performance evaluating means.
